Neurofibromatosis (NF) 1 and 2 have distinct appearance effects, yet little research has examined patients' appearance concerns. We assessed appearance concerns and self-consciousness, self-esteem, and loneliness among women with NF. Women with NF1 (n = 79) and NF2 (n = 48) completed the Derriford Appearance Scale to assess appearance concerns and sexual/bodily and social self-consciousness, Rosenberg Self-Esteem Scale, and UCLA Loneliness Scale. Women's appearance concerns were coded to determine whether they were NF-related and whether psychosocial factors contributed to the concerns. A total of 85% of women reported appearance concerns, many of which were NF-related and attributed to psychosocial factors. Women with NF1 reported significantly more sexual/bodily self-consciousness but similar levels of social self-consciousness compared with women with NF2. Significantly higher sexual/bodily self-consciousness was found among married/cohabiting women regardless of NF group. Compared with general population norms and breast cancer survivors (BCS), women with NF1 reported significantly greater sexual/bodily and social self-consciousness. Women with NF2 reported less sexual/bodily self-consciousness compared with population norms, yet tended to report greater sexual/bodily self-consciousness than BCS. Women with NF2 reported significantly greater social self-consciousness compared with population norms and BCS. For both NF1 and NF2, higher levels of sexual/bodily and social self-consciousness were related to lower self-esteem and higher levels of social self-consciousness to more loneliness. Appearance concerns are prevalent, and social self-consciousness is high, among women with NF1 and NF2. Women with NF1 compared with NF2 experience more sexual/bodily self-consciousness. Providers should assess the impact of NF on women's self-perceptions and address sexual, body image, and social concerns. Copyright © 2013 John Wiley & Sons, Ltd.

Self-consciousness concept and assessment in self-report measures

This study examines how self-consciousness is defined and assessed using self-report questionnaires (Self-Consciousness Scale (SCS), Self-Reflection and Insight Scale, Self-Absorption Scale, Rumination-Reflection Questionnaire, and Philadelphia Mindfulness Scale). Authors of self-report measures suggest that self-consciousness can be distinguished by its private/public aspects, its adaptive/maladaptive applied characteristics, and present/past experiences. We examined these claims in a study using 602 young adults to whom the aforementioned scales were administered. Data were analyzed as follows: (1) correlation analysis to find simple associations between the measures; (2) factorial analysis using Oblimin rotation of total scores provided from the scales; and (3) factorial analysis considering the 102 items of the scales all together. It aimed to clarify relational patterns found in the correlations between SCSs, and to identify possible latent constructs behind these scales. Results support the adaptive/maladaptive aspects of self-consciousness, as well as distinguish to some extent public aspects from private ones. However, some scales that claimed to be theoretically derived from the concept of Private Self-Consciousness correlated with some of its public self-aspects. Overall, our findings suggest that while self-reflection measures tend to tap into past experiences and judged concepts that were already processed by the participants’ inner speech and thoughts, the Awareness measure derived from Mindfulness Scale seems to be related to a construct associated with present experiences in which one is aware of without any further judgment or logical/rational symbolization. This sub-scale seems to emphasize the role that present experiences have in self-consciousness, and it is argued that such a concept refers to what has been studied by phenomenology and psychology over more than 100 years: the concept of pre-reflective self-conscious.

The correlates between public and private self-consciousness and internalizing difficulties were examined during early adolescence. Friendship quality was assessed as a possible moderator of the relation between self-consciousness and maladjustment. One hundred and thirty-seven young adolescents (N = 87 girls; M age = 13.98 years) reported on their self-consciousness, internalizing problems, and the quality of their best friendship. Results indicated stronger associations between private self-consciousness and internalizing correlates than between public self-consciousness and internalizing problems, suggesting that private self-consciousness may be a stronger risk factor during adolescence. Contrary to expectations, evidence revealed that positive friendship quality may exacerbate some difficulties associated with self-consciousness. Results pertaining to friendship quality add to the growing literature on the ways in which friendships can contribute to adjustment difficulties. PMID:19998530

2008-04-01

In this study we investigated the effects of state and trait aspects of self-focused attention on genital and subjective sexual arousal of sexually functional, healthy women during presentation of audiovisual erotic stimuli. Psychophysiological sexual response was measured as vaginal pulse amplitude using a vaginal photoplethysmograph. Experiential aspects of sexual arousal were measured both during stimulus presentation and retrospectively after stimulus offset. Trait level of sexual self-focus was measured with the Sexual Self-Consciousness Scale. State self-focus was induced by switching on a TV camera that pointed at the participant's face and upper torso. A manipulation check revealed that both groups experienced equally elevated levels of self-focused attention of their physical appearance. Induction of state self-focus per se did not affect genital responses, but an interaction effect of self-focus and participants' level of trait sexual self-focus was revealed. Compared with women with low scores on this trait, women with high scores exhibited smaller genital responses when state self-focus was induced. Both groups did not differ when no self-focus was induced. Increase of state self-focus did not affect subjective sexual arousal, but participants with a high level of trait sexual self-focus reported stronger subjective arousal, compared with those with low trait level. The results were discussed with reference to previous work in this field. Some implications for treatment of sexual arousal disorder were discussed.

Consciousness and stereoscopic environmental imaging

Mason, Steve

The question of human consciousness has intrigued philosophers and scientists for centuries: its nature, how we perceive our environment, how we think, our very awareness of thought and self. It has been suggested that stereoscopic vision is "a paradigm of how the mind works" 1 In depth perception, laws of perspective are known, reasoned, committed to memory from an early age; stereopsis, on the other hand, is a 3D experience governed by strict laws but actively joined within the brain―one sees it without explanation. How do we, in fact, process two different images into one 3D module within the mind and does an awareness of this process give us insight into the workings of our own consciousness? To translate this idea to imaging I employed ChromaDepth™ 3D glasses that rely on light being refracted in a different direction for each eye―colors of differing wavelengths appearing at varying distances from the viewer resulting in a 3D space. This involves neither calculation nor manufacture of two images or views. Environmental spatial imaging was developed―a 3D image was generated that literally surrounds the viewer. The image was printed and adhered to a semi-circular mount; the viewer then entered the interior to experience colored shapes suspended in a 3D space with an apparent loss of surface, or picture plane, upon which the image is rendered. By focusing our awareness through perception-based imaging we are able to gain a deeper understanding of how the brain works, how we see.

Identifying personality factors that account for individual differences in surgical training and performance has practical implications for surgical education. Movement-specific reinvestment is a potentially relevant personality factor that has a moderating effect on laparoscopic performance under time pressure. Movement-specific reinvestment has 2 dimensions, which represent an individual's propensity to consciously control movements (conscious motor processing) or to consciously monitor their 'style' of movement (movement self-consciousness). This study aimed at investigating the moderating effects of the 2 dimensions of movement-specific reinvestment in the learning and updating (cross-handed technique) of laparoscopic skills. Medical students completed the Movement-Specific Reinvestment Scale, a psychometric assessment tool that evaluates the conscious motor processing and movement self-consciousness dimensions of movement-specific reinvestment. They were then trained to a criterion level of proficiency on a fundamental laparoscopic skills task and were tested on a novel cross-handed technique. Completion times were recorded for early-learning, late-learning, and cross-handed trials. Propensity for movement self-consciousness but not conscious motor processing was a significant predictor of task completion times both early (p = 0.036) and late (p = 0.002) in learning, but completion times during the cross-handed trials were predicted by the propensity for conscious motor processing (p = 0.04) rather than movement self-consciousness (p = 0.21). Higher propensity for movement self-consciousness is associated with slower performance times on novel and well-practiced laparoscopic tasks. For complex surgical techniques, however, conscious motor processing plays a more influential role in performance than movement self-consciousness. The findings imply that these 2 dimensions of movement-specific reinvestment have a differential influence in the learning and updating

Dopamine levels in the brain influence human consciousness. Inspired by the role of Catechol-O-methyltransferase (COMT) in inactivating dopamine in the brain, we investigated to what extent COMT could modulate individual's self-consciousness dispositions and self-consistency by genotyping the COMT Val158Met (rs4680) polymorphism and measuring self-consciousness and self-consistency and congruence in a college student population. The results indicated that COMT Val158Met polymorphism significantly modulated the private self-consciousness. The individuals with Val/Val genotype, corresponding to lower dopamine levels in the brain, were more likely to be aware of their feelings and beliefs. The results also indicated that this polymorphism modulated one's self-flexibility. The individuals with Val/Val genotype showed higher levels of stereotype in self-concept compared with those with Met/Met genotype. These findings suggest that COMT is a predictor of the individual differences in self-consciousness and self-flexibility. Copyright © 2016 Elsevier Inc. All rights reserved.

HPV knowledge and impact of genital warts on self esteem and sexual life in Colombian patients

PubMed Central

2013-01-01

Background Information on HPV knowledge in patients with genital warts is scarse as is the information on factors related to the impact on self-esteem and sex life among them. Methods We conducted a cross-sectional study in adult patients with a clinical diagnosis of genital warts (GW) attending a major private out-patient clinic in Bogotá, Colombia. Patients underwent biopsy for pathological diagnosis, HPV-DNA testing and completed a questionnaire assessing HPV knowledge, and the consequences of GW on self-esteem and sexual life. Differences in proportions were assessed with a chi2 test. Results 106 men and 155 women had pathologic confirmation of GW. 51% of subjects had heard of HPV before consultation coming mainly from the media (82%). Less than half of the participants knew that HPV could be transmitted through non-penetrant sexual intercourse and only two thirds acknowledged HPV vaccine as a preventive measure against HPV infection. Impact on self-esteem was higher among women than men (90.3% vs 60.4%, [p < 0.01]). In men, factors related to a higher impact on sexual life were HPV awareness and age; in women they were higher education and anatomic location; external GW had a higher impact on sexual life in women (83% vs. 66%; [p = 0.05]). Conclusions We found a low awareness of HPV and low knowledge on the vaccine as a preventive measure for associated diseases even in patients suffering from genital warts, highlighting the need for communication and education on HPV. Greater impact on self-esteem in women might reflect higher health consciousness among Latin American women. PMID:23530591

Object of desire self-consciousness theory.

PubMed

Bogaert, Anthony F; Brotto, Lori A

2014-01-01

In this article, the authors discuss the construct of object of desire self-consciousness, the perception that one is romantically and sexually desirable in another's eyes. The authors discuss the nature of the construct, variations in its expression, and how it may function as part of a self-schemata or script related to romance and sexuality. The authors suggest that object of desire self-consciousness may be an adaptive, evolved psychological mechanism allowing sexual and romantic tactics suitable to one's mate value. The authors also suggest that it can act as a signal that one has high mate value in the sexual marketplace. The authors then review literature (e.g., on fantasies, on sexual activity preferences, on sexual dysfunctions, on language) suggesting that object of desire self-consciousness plays a particularly important role in heterosexual women's sexual/romantic functioning and desires.

To assess the perceptions of healthy men of their genital anatomy and sexual sensitivity, along with the re-test reliability of these ratings, in a new self-reported questionnaire, the Self-Assessment of Genital Anatomy and Sexual Function, Male (SAGASF-M). Eighty-one healthy, sexually active, men aged 22-57 years (median 33), with no history of genital surgery, completed the SAGASF-M. This questionnaire comprises written text and images enabling men to rate details of their genital appearance, overall genital erotic and pain sensitivity, orgasm intensity, and effort required for achieving orgasm through stimulation of specified areas around the glans and shaft of the penis, scrotum and anus, along with the contribution of other sexually sensitive areas of the body. Anatomical locations were compared for the functional ratings by mixed-model analysis of variance (anova). A second sample of 38 healthy men (median age 26 years, range 22-64) from the same source completed the SAGASF-M twice with an interval of 2 weeks. There was little variability in anatomy ratings. Ratings of overall penile sensitivity to sexual stimulation gave higher values of 'sexual pleasure' for penile stimulation by the partner than by self (P = 0.002) and marginally higher ratings of 'orgasm intensity' by partner stimulation (P = 0.077), but there were no corresponding differences on ratings of 'effort needed to reach orgasm' or of 'discomfort/pain'. Overall discrimination between genital areas was highly significant (mixed-model anova, P = 0.001) for ratings of 'sexual pleasure', 'orgasm intensity' and 'orgasm effort', but was not significant for 'discomfort/pain'. Ranked by degree of 'sexual pleasure', the area 'underside of the glans' was highest, followed by 'underside of the penile shaft', 'upper side of the glans', 'left and right sides of the glans', 'one or both sides of the penis', 'upper side of the penile shaft', 'foreskin' (11 subjects), 'skin between the scrotum and anus', 'back

Neural correlates of processing "self-conscious" vs. "basic" emotions.

Self-conscious emotions are prevalent in our daily lives and play an important role in both normal and pathological behavior. Despite their immense significance, the neural substrates that are involved in the processing of such emotions are surprisingly under-studied. In light of this, we conducted an fMRI study in which participants thought of various personal events which elicited feelings of negative and positive self-conscious (i.e., guilt, pride) or basic (i.e., anger, joy) emotions. We performed a conjunction analysis to investigate the neural correlates associated with processing events that are related to self-conscious vs. basic emotions, irrespective of valence. The results show that processing self-conscious emotions resulted in activation within frontal areas associated with self-processing and self-control, namely, the mPFC extending to the dACC, and within the lateral-dorsal prefrontal cortex. Processing basic emotions resulted in activation throughout relatively phylogenetically-ancient regions of the cortex, namely in visual and tactile processing areas and in the insular cortex. Furthermore, self-conscious emotions differentially activated the mPFC such that the negative self-conscious emotion (guilt) was associated with a more dorsal activation, and the positive self-conscious emotion (pride) was associated with a more ventral activation. We discuss how these results shed light on the nature of mental representations and neural systems involved in self-reflective and affective processing. Copyright © 2015 Elsevier Ltd.

Age and the experience of strong self-conscious emotion.

It remains unclear whether there are age-related changes in the experience of strong self-conscious emotion, such as shame, guilt, pride and embarrassment. Because shame and guilt figure prominently in the aetiology of depressive symptoms and other mental health problems, a better understanding of how age affects the strong experience of these two negative self-conscious emotions is of particular importance. Thirty younger, 30 middle-aged and 30 older adults were compared on standardised cognitive assessments, in addition to an interview-based measure that assessed whether there are age differences in the likelihood of strongly experiencing four different types of self-conscious emotion within the past five years (shame, guilt, embarrassment and pride). The three groups did not differ in their likelihood of reporting an event that strongly elicited the positive self-conscious emotion of pride. However, older adults were more likely to report sources of pride that were other (as opposed to self) focused. Older adults were also less likely to report experiencing events that elicited all three negative self-conscious emotions, in particular, shame. Strong negative self-conscious emotion, and in particular shame, appears to be experienced less by older than younger adults.

Evolutionary aspects of self- and world consciousness in vertebrates

Although most aspects of world and self-consciousness are inherently subjective, neuroscience studies in humans and non-human animals provide correlational and causative indices of specific links between brain activity and representation of the self and the world. In this article we review neuroanatomic, neurophysiological and neuropsychological data supporting the hypothesis that different levels of self and world representation in vertebrates rely upon (i) a “basal” subcortical system that includes brainstem, hypothalamus and central thalamic nuclei and that may underpin the primary (or anoetic) consciousness likely present in all vertebrates; and (ii) a forebrain system that include the medial and lateral structures of the cerebral hemispheres and may sustain the most sophisticated forms of consciousness [e.g., noetic (knowledge based) and autonoetic, reflective knowledge]. We posit a mutual, bidirectional functional influence between these two major brain circuits. We conclude that basic aspects of consciousness like primary self and core self (based on anoetic and noetic consciousness) are present in many species of vertebrates and that, even self-consciousness (autonoetic consciousness) does not seem to be a prerogative of humans and of some non-human primates but may, to a certain extent, be present in some other mammals and birds PMID:25859205

The default mode network (DMN) has been consistently activated across a wide variety of self-related tasks, leading to a proposal of the DMN's role in self-related processing. Indeed, there is limited fMRI evidence that the functional connectivity within the DMN may underlie a phenomenon referred to as self-awareness. At the same time, none of the known studies have explicitly investigated neuronal functional interactions among brain areas that comprise the DMN as a function of self-consciousness loss. To fill this gap, EEG operational synchrony analysis [1, 2] was performed in patients with severe brain injuries in vegetative and minimally conscious states to study the strength of DMN operational synchrony as a function of self-consciousness expression. We demonstrated that the strength of DMN EEG operational synchrony was smallest or even absent in patients in vegetative state, intermediate in patients in minimally conscious state and highest in healthy fully self-conscious subjects. At the same time the process of ecoupling of operations performed by neuronal assemblies that comprise the DMN was highest in patients in vegetative state, intermediate in patients in minimally conscious state and minimal in healthy fully self-conscious subjects. The DMN's frontal EEG operational module had the strongest decrease in operational synchrony strength as a function of selfconsciousness loss, when compared with the DMN's posterior modules. Based on these results it is suggested that the strength of DMN functional connectivity could mediate the strength of self-consciousness expression. The observed alterations similarly occurred across EEG alpha, beta1 and beta2 frequency oscillations. Presented results suggest that the EEG operational synchrony within DMN may provide an objective and accurate measure for the assessment of signs of self-(un)consciousness in these challenging patient populations. This method therefore, may complement the current diagnostic procedures for

Public self-consciousness moderates the link between displacement behaviour and experience of stress in women.

PubMed

When stressed, people typically show elevated rates of displacement behaviour--activities such as scratching and face touching that seem irrelevant to the ongoing situation. Growing evidence indicates that displacement behaviour may play a role in regulating stress levels, and thus may represent an important component of the coping response. Recently, we found evidence that this stress-regulating effect of displacement behaviour is found in men but not in women. This sex difference may result from women's higher levels of public self-consciousness, which could inhibit expression of displacement behaviour due to the fear of projecting an inappropriate image. Here, we explored the link between public self-consciousness, displacement behaviour and stress among 62 healthy women (mean age = 26.59 years; SD = 3.61). We first assessed participants' public self-consciousness, and then quantified displacement behaviour, heart rate and cognitive performance during a Trier Social Stress Test (TSST) and used self-report questionnaires to assess the experience of stress afterwards. Public self-consciousness was negatively correlated with rate of displacement behaviour, and positively correlated with both the subjective experience of stress post-TSST and the number of mistakes in the cognitive task. Moderation analyses revealed that for women high in public self-consciousness, high levels of displacement behaviour were associated with higher reported levels of stress and poorer cognitive performance. For women low in public self-consciousness, stress levels and cognitive performance were unrelated to displacement behaviour. Our findings indicate that public self-consciousness is associated with both the expression of displacement behaviour and how such behaviour mediates responses to social stress.

Breathing and sense of self: visuo-respiratory conflicts alter body self-consciousness.

PubMed

Adler, Dan; Herbelin, Bruno; Similowski, Thomas; Blanke, Olaf

2014-11-01

Bodily self-consciousness depends on the processing of interoceptive and exteroceptive signals. It can be disrupted by inducing signal conflicts. Breathing, at the crossroad between interoception and exteroception, should contribute to bodily self-consciousness. We induced visuo-respiratory conflicts in 17 subjects presented with a virtual body or a parallelepidedal object flashing synchronously or asynchronously with their breathing. A questionnaire detected illusory changes in bodily self-consciousness and breathing agency (the feeling of sensing one's breathing command). Changes in self-location were tested by measuring reaction time during mental ball drop (MBD). Synchronous illumination changed the perceived location of breathing (body: p=0.008 vs. asynchronous; object: p=0.013). It resulted in a significant change in breathing agency, but no changes in self-identification. This was corroborated by prolonged MBD reaction time (body: +0.045s, 95%CI [0.013; 0.08], p=0.007). We conclude that breathing modulates bodily self-consciousness. We also conclude that one can induce the irruption of unattended breathing into consciousness without modifying respiratory mechanics or gas exchange. Copyright © 2014 Elsevier B.V.

Diminished Self-Conscious Emotional Responding in Frontotemporal Lobar Degeneration Patients

2009-01-01

Frontotemporal lobar degeneration (FTLD) is a neurodegenerative disease that dramatically alters social and emotional behavior. Recent work has suggested that self-conscious emotions (e.g., embarrassment) may be particularly vulnerable to disruption in this disease. Self-conscious emotions require the ability to monitor the self in relation to others. These abilities are thought to be subserved by brain regions (e.g., medial prefrontal, anterior cingulate, and insula) that are particularly vulnerable to damage in FTLD. This study examined emotional responding (expressive behavior, peripheral physiology, and subjective experience) in 24 FTLD patients and 16 cognitively normal control participants using a karaoke task known to elicit self-conscious emotion reliably and a nonemotional control task (isometric handgrip). Results indicated that FTLD patients showed diminished self-conscious emotional behavior (embarrassment and amusement) and diminished physiological responding while watching themselves singing. No differences were found between patients and controls in the nonemotional control task. These findings offer evidence of marked disruption of self-conscious emotional responding in FTLD. Diminished self-conscious emotional responding likely contributes significantly to social inappropriateness and other behavioral abnormalities in FTLD. PMID:19102597

Recent evidence suggests that multisensory integration of bodily signals involving exteroceptive and interoceptive information modulates bodily aspects of self-consciousness such as self-identification and self-location. In the so-called Full Body Illusion subjects watch a virtual body being stroked while they perceive tactile stimulation on their own body inducing illusory self-identification with the virtual body and a change in self-location towards the virtual body. In a related illusion, it has recently been shown that similar changes in self-identification and self-location can be observed when an interoceptive signal is used in association with visual stimulation of the virtual body (i.e., participants observe a virtual body illuminated in synchrony with their heartbeat). Although brain imaging and neuropsychological evidence suggest that the insular cortex is a core region for interoceptive processing (such as cardiac perception and awareness) as well as for self-consciousness, it is currently not known whether the insula mediates cardio-visual modulation of self-consciousness. Here we tested the involvement of insular cortex in heartbeat awareness and cardio-visual manipulation of bodily self-consciousness in a patient before and after resection of a selective right neoplastic insular lesion. Cardio-visual stimulation induced an abnormally enhanced state of bodily self-consciousness; in addition, cardio-visual manipulation was associated with an experienced loss of the spatial unity of the self (illusory bi-location and duplication of his body), not observed in healthy subjects. Heartbeat awareness was found to decrease after insular resection. Based on these data we propose that the insula mediates interoceptive awareness as well as cardio-visual effects on bodily self-consciousness and that insular processing of interoceptive signals is an important mechanism for the experienced unity of the self.

2003-08-01

This study examined the relation of personality traits--shame-proneness, guilt-proneness, and pride--on offending behavior. Using survey data from a sample of 224 college students, the construct and criterion-related validity of scales of the Shame Proneness Scale, the Test of Self-conscious Affect, and the Personality Feelings Questionnaire-2 were assessed. Regression analyses showed that self-conscious emotions are important in the etiology of criminal offending. Specifically, rated pride was positively correlated with self-reported criminal activity, whereas ratings of guilt were negatively associated with offending. The relation of shame with criminality varied depending on the type of measure used to indicate proneness to shame.

Results indicated that FTLD patients showed diminished self-conscious emotional behavior (embarrassment and amusement) and diminished physiological responding while watching themselves singing. No differences were found between patients and controls in the nonemotional control task. These findings offer evidence of marked disruption of self-conscious emotional responding in FTLD. Diminished self-conscious emotional responding likely contributes significantly to social inappropriateness and other behavioral abnormalities in FTLD. 2008 APA, all rights reserved

The relationships among Black consciousness, self-esteem, and academic self-efficacy in African American men.

PubMed

Okech, Allan Prince; Harrington, Rick

2002-03-01

The purpose of this study was to investigate the relationships among Black consciousness, self-esteem, and academic self-efficacy in African American men. The participants were 120 African American male college students at a predominantly African American university. The authors administered 3 instruments--the Developmental Inventory of Black Consciousness (DIB-C; J. Milliones, 1980), the M. Rosenberg (1965) Self-Esteem Scale, and R. E. Wood and E. A. Locke's (1987) Academic Self-Efficacy Scale--to test the hypotheses. They used an independent-measures t test and a Pearson r correlation to analyze the data. The results of the study supported the hypotheses under investigation. Significant positive relationships were found between Black consciousness and self-esteem and Black consciousness and academic self-efficacy. The results of the study showed that Black consciousness appears to be an important construct to use in understanding self-esteem and academic self-efficacy in African American men.

Gynephilic Men's Self-Reported and Genital Sexual Responses to Relationship Context Cues.

PubMed

Timmers, Amanda D; Chivers, Meredith L

2018-04-01

The current study examined men's sexual responses to relationship context. Chivers and Timmers (2012) previously reported that heterosexual men's genital and self-reported sexual arousal varied by gender but not relationship context, suggesting that gender cues are more salient determinants of sexual response than relationship context cues for men. Those analyses were, however, significantly underpowered to detect relationship context effects (n = 9). The current study utilized the same paradigm as Chivers and Timmers' study, exposing a larger sample of heterosexual men (n = 26) to audio narratives describing sexual interactions that varied by partner gender (man, woman) and relationship context (stranger, friend, long-term relationship), and observing effects on genital and self-reported sexual response. Results indicated that men's genital response to relationship context cues mirrored those previously reported for heterosexual women (Chivers & Timmers, 2012); heterosexual men demonstrated less genital response to the friend than to the stranger or long-term relationship conditions. No significant effect of relationship context was found for men's self-reported sexual arousal. These data suggest that, in addition to gender cues, relationship cues may also be an important determinant of men's genital sexual responses.

Recent research has investigated self-consciousness associated with the multisensory processing of bodily signals (e.g., somatosensory, visual, vestibular signals), a notion referred to as bodily self-consciousness, and these studies have shown that the manipulation of bodily inputs induces changes in bodily self-consciousness such as self-identification. Another line of research has highlighted the importance of signals from the inside of the body (e.g., visceral signals) and proposed that neural representations of internal bodily signals underlie self-consciousness, which to date has been based on philosophical inquiry, clinical case studies, and behavioral studies. Here, we investigated the relationship of bodily self-consciousness with the neural processing of internal bodily signals. By combining electrical neuroimaging, analysis of peripheral physiological signals, and virtual reality technology in humans, we show that transient modulations of neural responses to heartbeats in the posterior cingulate cortex covary with changes in bodily self-consciousness induced by the full-body illusion. Additional analyses excluded that measured basic cardiorespiratory parameters or interoceptive sensitivity traits could account for this finding. These neurophysiological data link experimentally the cortical mapping of the internal body to self-consciousness. What are the brain mechanisms of self-consciousness? Prominent views propose that the neural processing associated with signals from the internal organs (such as the heart and the lung) plays a critical role in self-consciousness. Although this hypothesis dates back to influential views in philosophy and psychology (e.g., William James), definitive experimental evidence supporting this idea is lacking despite its recent impact in neuroscience. In the present study, we show that posterior cingulate activities responding to heartbeat signals covary with changes in participants' conscious self-identification with a body

The regulatory function of self-conscious emotion: insights from patients with orbitofrontal damage.

2003-10-01

Although once considered disruptive, self-conscious emotions are now theorized to be fundamentally involved in the regulation of social behavior. The present study examined the social regulation function of self-conscious emotions by comparing healthy participants with a neuropsychological population--patients with orbitofrontal lesions--characterized by selective regulatory deficits. Orbitofrontal patients and healthy controls participated in a series of tasks designed to assess their social regulation and self-conscious emotions. Another task assessed the ability to infer others' emotional states, an appraisal process involved in self-conscious emotion. Consistent with the theory that self-conscious emotions are important for regulating social behavior, the findings show that deficient behavioral regulation is associated with inappropriate self-conscious emotions that reinforce maladaptive behavior. Additionally, deficient behavioral regulation is associated with impairments in interpreting the self-conscious emotions of others.

Images of the Self and Self-Esteem: Do Positive Self-Images Improve Self-Esteem in Social Anxiety?

PubMed Central

Hulme, Natalie; Hirsch, Colette; Stopa, Lusia

2012-01-01

Negative self-images play an important role in maintaining social anxiety disorder. We propose that these images represent the working self in a Self-Memory System that regulates retrieval of self-relevant information in particular situations. Self-esteem, one aspect of the working self, comprises explicit (conscious) and implicit (automatic) components. Implicit self-esteem reflects an automatic evaluative bias towards the self that is normally positive, but is reduced in socially anxious individuals. Forty-four high and 44 low socially anxious participants generated either a positive or a negative self-image and then completed measures of implicit and explicit self-esteem. Participants who held a negative self-image in mind reported lower implicit and explicit positive self-esteem, and higher explicit negative self-esteem than participants holding a positive image in mind, irrespective of social anxiety group. We then tested whether positive self-images protected high and low socially anxious individuals equally well against the threat to explicit self-esteem posed by social exclusion in a virtual ball toss game (Cyberball). We failed to find a predicted interaction between social anxiety and image condition. Instead, all participants holding positive self-images reported higher levels of explicit self-esteem after Cyberball than those holding negative self-images. Deliberate retrieval of positive self-images appears to facilitate access to a healthy positive implicit bias, as well as improving explicit self-esteem, whereas deliberate retrieval of negative self-images does the opposite. This is consistent with the idea that negative self-images may have a causal, as well as a maintaining, role in social anxiety disorder. PMID:22439697

A fast automatic recognition and location algorithm for fetal genital organs in ultrasound images.

PubMed

Tang, Sheng; Chen, Si-ping

2009-09-01

Severe sex ratio imbalance at birth is now becoming an important issue in several Asian countries. Its leading immediate cause is prenatal sex-selective abortion following illegal sex identification by ultrasound scanning. In this paper, a fast automatic recognition and location algorithm for fetal genital organs is proposed as an effective method to help prevent ultrasound technicians from unethically and illegally identifying the sex of the fetus. This automatic recognition algorithm can be divided into two stages. In the 'rough' stage, a few pixels in the image, which are likely to represent the genital organs, are automatically chosen as points of interest (POIs) according to certain salient characteristics of fetal genital organs. In the 'fine' stage, a specifically supervised learning framework, which fuses an effective feature data preprocessing mechanism into the multiple classifier architecture, is applied to every POI. The basic classifiers in the framework are selected from three widely used classifiers: radial basis function network, backpropagation network, and support vector machine. The classification results of all the POIs are then synthesized to determine whether the fetal genital organ is present in the image, and to locate the genital organ within the positive image. Experiments were designed and carried out based on an image dataset comprising 658 positive images (images with fetal genital organs) and 500 negative images (images without fetal genital organs). The experimental results showed true positive (TP) and true negative (TN) results from 80.5% (265 from 329) and 83.0% (415 from 500) of samples, respectively. The average computation time was 453 ms per image.

The Structure of Conscious Bodily Self-Perception during Full-Body Illusions

Dobricki, Martin; de la Rosa, Stephan

2013-01-01

Previous research suggests that bodily self-identification, bodily self-localization, agency, and the sense of being present in space are critical aspects of conscious full-body self-perception. However, none of the existing studies have investigated the relationship of these aspects to each other, i.e., whether they can be identified to be distinguishable components of the structure of conscious full-body self-perception. Therefore, the objective of the present investigation is to elucidate the structure of conscious full-body self-perception. We performed two studies in which we stroked the back of healthy individuals for three minutes while they watched the back of a distant virtual body being synchronously stroked with a virtual stick. After visuo-tactile stimulation, participants assessed changes in their bodily self-perception with a custom made self-report questionnaire. In the first study, we investigated the structure of conscious full-body self-perception by analyzing the responses to the questionnaire by means of multidimensional scaling combined with cluster analysis. In the second study, we then extended the questionnaire and validated the stability of the structure of conscious full-body self-perception found in the first study within a larger sample of individuals by performing a principle components analysis of the questionnaire responses. The results of the two studies converge in suggesting that the structure of conscious full-body self-perception consists of the following three distinct components: bodily self-identification, space-related self-perception (spatial presence), and agency.

Consciousness and body image: lessons from phantom limbs, Capgras syndrome and pain asymbolia.

PubMed Central

Ramachandran, V S

1998-01-01

Words such as 'consciousness' and 'self' actually encompass a number of distinct phenomena that are loosely lumped together. The study of neurological syndromes allows us to explore the neural mechanisms that might underlie different aspects of self, such as body image and emotional responses to sensory stimuli, and perhaps even laughter and humour. Mapping the 'functional logic' of the many different attributes of human nature on to specific neural circuits in the brain offers the best hope of understanding how the activity of neurons gives rise to conscious experience. We consider three neurological syndromes (phantom limbs, Capgras delusion and pain asymbolia) to illustrate this idea. PMID:9854257

The vestibular system: a spatial reference for bodily self-consciousness

PubMed Central

Pfeiffer, Christian; Serino, Andrea; Blanke, Olaf

Self-consciousness is the remarkable human experience of being a subject: the “I”. Self-consciousness is typically bound to a body, and particularly to the spatial dimensions of the body, as well as to its location and displacement in the gravitational field. Because the vestibular system encodes head position and movement in three-dimensional space, vestibular cortical processing likely contributes to spatial aspects of bodily self-consciousness. We review here recent data showing vestibular effects on first-person perspective (the feeling from where “I” experience the world) and self-location (the feeling where “I” am located in space). We compare these findings to data showing vestibular effects on mental spatial transformation, self-motion perception, and body representation showing vestibular contributions to various spatial representations of the body with respect to the external world. Finally, we discuss the role for four posterior brain regions that process vestibular and other multisensory signals to encode spatial aspects of bodily self-consciousness: temporoparietal junction, parietoinsular vestibular cortex, ventral intraparietal region, and medial superior temporal region. We propose that vestibular processing in these cortical regions is critical in linking multisensory signals from the body (personal and peripersonal space) with external (extrapersonal) space. Therefore, the vestibular system plays a critical role for neural representations of spatial aspects of bodily self-consciousness. PMID:24860446

Dental anxiety and personality: investigating the relationship between dental anxiety and self-consciousness.

PubMed

Economou, George C

2003-09-01

This study investigated whether personality plays a role in a condition called dental anxiety. Specifically, the study examined the relationship between dental anxiety (the negative response to the stress elicited from a dental interaction) and self-consciousness (the tendency to evaluate aspects of oneself that are subject to private and public display). The purpose of this study was to identify the characteristics possessed by dentally anxious individuals who face potential health risks because of their avoidance. Sixty York University undergraduate students were recruited by convenience sampling to participate. These subjects completed Corah's Dental Anxiety Scale and the Self-Consciousness Scale. The Self-Consciousness Scale consists of three subscales, including private self-consciousness, public self-consciousness, and social anxiety. Results indicated an 0.54 significant correlation between dental anxiety and self-consciousness. The public self-consciousness and social anxiety subscales correlated the most with dental anxiety. Furthermore, the data did not indicate a significant moderating relationship for gender between the two aforementioned variables. These results contribute to the establishment of personality characteristics as one of the dimensions determining dental anxiety.

To investigate Beijing college students' self-consciousness and its relationship with mental health. Convenient samples of 928 college students from five universities in Beijing were inquired and assessed with the self-consciousness scale and the Kessler 10 psychological distress scale. Confirmatory factor analysis and structural equation modeling were used to analyze the data. College students' scores of self-consciousness did not differ in sex, age, grade and major type. 83.5% of the participants had relatively low scores (10-24) of psychological distress, but those of the students of liberal arts were higher (P < 0.05). The measurement data of self-consciousness supported Mittal and Balasubramanian' s five-factor structure. Self-reflectiveness was positively correlated with depression (P < 0.05). Internal state awareness was negatively associated with both anxiety and depression (P < 0.05). Style consciousness was positively correlated with both of them (P < 0.001). Beijing college students' self-consciousness is relatively high and has a relatively complex structure. While self-reflectiveness and style consciousness have negative effects, internal state awareness is good for mental health.

Supporting the self-regulatory resource: does conscious self-regulation incidentally prime nonconscious support processes?

PubMed

Dorris, Derek C

2009-11-01

Ego-depletion (depletion of self-regulatory strength) can impair conscious efforts at self-regulation. Research into nonconscious self-regulation has demonstrated that preconscious automaticity and implementation intentions can automatically carry out regulatory tasks during times of ego-depletion. However, preconscious automaticity can only emerge during well-practiced tasks while implementation intentions can only support tasks that have been explicitly planned. Thus, when it comes to supporting the conscious self-regulation of nonroutine and unplanned behaviour during times of ego-depletion these processes should be ineffective. However, it is argued here that because the conscious self-regulation of nonroutine and unplanned behaviour can incidentally prime the underlying mental representations those primed representations can be postconsciously re-activated to support that behaviour during times of ego-depletion. Postconscious self-regulation might, therefore, support a type of self-regulatory behaviour that has, thus far, not been associated with any form of support.

The temporal structure of resting-state brain activity in the medial prefrontal cortex predicts self-consciousness.

2016-02-01

Recent studies have demonstrated an overlap between the neural substrate of resting-state activity and self-related processing in the cortical midline structures (CMS). However, the neural and psychological mechanisms mediating this so-called "rest-self overlap" remain unclear. To investigate the neural mechanisms, we estimated the temporal structure of spontaneous/resting-state activity, e.g. its long-range temporal correlations or self-affinity across time as indexed by the power-law exponent (PLE). The PLE was obtained in resting-state activity in the medial prefrontal cortex (MPFC) and the posterior cingulate cortex (PCC) in 47 healthy subjects by functional magnetic resonance imaging (fMRI). We performed correlation analyses of the PLE and Revised Self-Consciousness Scale (SCSR) scores, which enabled us to access different dimensions of self-consciousness and specified rest-self overlap in a psychological regard. The PLE in the MPFC's resting-state activity correlated with private self-consciousness scores from the SCSR. Conversely, we found no correlation between the PLE and the other subscales of the SCSR (public, social) or between other resting-state measures, including functional connectivity, and the SCSR subscales. This is the first evidence for the association between the scale-free dynamics of resting-state activity in the CMS and the private dimension of self-consciousness. This finding implies the relationship of especially the private dimension of self with the temporal structure of resting-state activity. Copyright © 2016 Elsevier Ltd. All rights reserved.

Narcissism: its function in modulating self-conscious emotions.

PubMed

Uji, Masayo; Nagata, Toshiaki; Kitamura, Toshinori

2012-01-01

This study focused on the functional aspects of narcissism in regulating self-conscious emotions (guilt, shame, hubristic pride, and achievement-oriented pride) as well as two other attribution styles (externalization and detachment). The authors investigated Japanese university students (N = 452) with regard to their self-conscious emotions using the Test of Self-Conscious Affect-3 (TOSCA-3) and their narcissistic personality using the short version of Narcissistic Personality Inventory (NPI-S). Structural equation modeling was used for the analysis. The authors found that narcissism led individuals to feel achievement-oriented pride, hubristic pride, externalization, and detachment, but inhibited feelings of shame. It did not have a significant effect on guilt. Shame-proneness prompted hubristic pride and externalization. Guilt-proneness inclined an individual toward achievement-oriented pride, but deterred externalization. In this article, the authors present and interpret these results in detail and then discuss how they can be utilized in psychotherapy.

Making sense of self-conscious emotion: linking theory of mind and emotion in children with autism.

Heerey, Erin A; Keltner, Dacher; Capps, Lisa M

2003-12-01

Self-conscious emotions such as embarrassment and shame are associated with 2 aspects of theory of mind (ToM): (a) the ability to understand that behavior has social consequences in the eyes of others and (b) an understanding of social norms violations. The present study aimed to link ToM with the recognition of self-conscious emotion. Children with and without autism identified facial expressions conscious of self-conscious and non-self-conscious emotions from photographs. ToM was also measured. Children with autism performed more poorly than comparison children at identifying self-conscious emotions, though they did not differ in the recognition of non-self-conscious emotions. When ToM ability was statistically controlled, group differences in the recognition of self-conscious emotion disappeared. Discussion focused on the links between ToM and self-conscious emotion.

Effects of self-consciousness and social anxiety on self-disclosure among unacquainted individuals: an application of the social relations model.

PubMed

Reno, R R; Kenny, D A

1992-03-01

Recent research has demonstrated a positive relationship between private self-consciousness and the tendency to self-disclose. These studies have relied exclusively upon self-reports of disclosure. In the present study, Kenny's Social Relations Model (Kenny & La Voie, 1984) was employed to examine the relationship between a subject's self-reports and others' reports of a subject's level of self-disclosure and the relationship of these reports to private self-consciousness, as well as the other traits measured by the self-consciousness scale: public self-consciousness and social anxiety. Unacquainted college women (N = 102) participated in one-on-one interactions in a round-robin design. Subject's self-reports of disclosure and their levels of private self-consciousness correlated positively. The partners' reports of an individual's disclosure, however, were not related to the individual's level of private self-consciousness. The discrepancy between these correlations emphasizes the necessity to ground research in personal relationships on interacting pairs and not only on the self-reports of one member. Future research that would explore this difference is discussed. The examination of the self- and partner reports and subjects' levels of public self-consciousness and social anxiety demonstrated that these two traits significantly influence the acquaintance process. Public self-consciousness related positively to subjects' beliefs that they had created consistent impressions upon their partners. Social anxiety correlated negatively with partners' reports of a subject's dyadic involvement and openness.

This study aimed to explore the extent to which self-conscious emotions are expressed, to explore any associations with adverse health outcomes, and to compare self-conscious emotions in individuals with chronic obstructive pulmonary disease (COPD) to healthy controls. A two-stage mixed-methods study design was employed. Interviews with 15 individuals with COPD informed the choice of questionnaires to assess self-conscious emotions which were completed by individuals with COPD and healthy controls. Five overarching themes were abstracted: grief, spectrum of blame, concern about the view of others, concealment, and worry about the future. The questionnaires were completed by 70 patients (mean( SD) age 70.8(9.4) years, forced expiratory volume in one second predicted 40.5(18.8), 44% male) and 61 healthy controls (mean( SD) age 62.2(12.9) years, 34% male]. Self-conscious emotions were associated with reduced mastery, heightened emotions, and elevated anxiety and depression (all p < 0.001). Individuals with COPD reported lower self-compassion, higher shame, and less pride than healthy controls (all p ≤ 0.01). There is a need to increase awareness of self-conscious emotions in individuals with COPD. Therapies to target such emotions may improve mastery, emotions, and psychological symptoms.

This study examined the moderating effect of self-esteem on the relationship between public self-consciousness and social anxiety, and on the relationship between public self-consciousness and exhibitionism in Japan and South Korea. The participants were 213 university students in Japan and 234 university students in Korea. The results of hierarchical multiple regression analyses showed that self-esteem was a moderator of the relationship between public self-consciousness and social anxiety and of the relationship between public self-consciousness and exhibitionism in Korea, but not in Japan. In Korea, public self-consciousness was related to social anxiety for people with low self-esteem, while for people with high self-esteem, public self-consciousness was related to exhibitionism.

Brain activations during judgments of positive self-conscious emotion and positive basic emotion: pride and joy.

We aimed to investigate the neural correlates associated with judgments of a positive self-conscious emotion, pride, and elucidate the difference between pride and a basic positive emotion, joy, at the neural basis level using functional magnetic resonance imaging. Study of the neural basis associated with pride might contribute to a better understanding of the pride-related behaviors observed in neuropsychiatric disorders. Sixteen healthy volunteers were studied. The participants read sentences expressing joy or pride contents during the scans. Pride conditions activated the right posterior superior temporal sulcus and left temporal pole, the regions implicated in the neural substrate of social cognition or theory of mind. However, against our prediction, we did not find brain activation in the medial prefrontal cortex, a region responsible for inferring others' intention or self-reflection. Joy condition produced activations in the ventral striatum and insula/operculum, the key nodes of processing of hedonic or appetitive stimuli. Our results support the idea that pride is a self-conscious emotion, requiring the ability to detect the intention of others. At the same time, judgment of pride might require less self-reflection compared with those of negative self-conscious emotions such as guilt or embarrassment.

Exploring Cultural Differences in the Recognition of the Self-Conscious Emotions.

PubMed

Chung, Joanne M; Robins, Richard W

2015-01-01

Recent research suggests that the self-conscious emotions of embarrassment, shame, and pride have distinct, nonverbal expressions that can be recognized in the United States at above-chance levels. However, few studies have examined the recognition of these emotions in other cultures, and little research has been conducted in Asia. Consequently the cross-cultural generalizability of self-conscious emotions has not been firmly established. Additionally, there is no research that examines cultural variability in the recognition of the self-conscious emotions. Cultural values and exposure to Western culture have been identified as contributors to variability in recognition rates for the basic emotions; we sought to examine this for the self-conscious emotions using the University of California, Davis Set of Emotion Expressions (UCDSEE). The present research examined recognition of the self-conscious emotion expressions in South Korean college students and found that recognition rates were very high for pride, low but above chance for shame, and near zero for embarrassment. To examine what might be underlying the recognition rates we found in South Korea, recognition of self-conscious emotions and several cultural values were examined in a U.S. college student sample of European Americans, Asian Americans, and Asian-born individuals. Emotion recognition rates were generally similar between the European Americans and Asian Americans, and higher than emotion recognition rates for Asian-born individuals. These differences were not explained by cultural values in an interpretable manner, suggesting that exposure to Western culture is a more important mediator than values.

These differences were not explained by cultural values in an interpretable manner, suggesting that exposure to Western culture is a more important mediator than values. PMID:26309215

Self-reports of mathematics self-concept and educational outcomes: the roles of ego-dimensions and self-consciousness.

Martin, A J; Debus, R L

There is a need for research to (a) explore more fully the academic outcomes that follow from under-/over-rating of self-concept and (b) identify factors that predict the nature of self-reports of self-concept as well as under- and over-rating of this self-concept. The study examines the link between students' self-appraisals of both mathematics self-concept and under-/over-rating of this self-concept and educational outcomes in mathematics such as achievement and motivation (future plans for mathematics). Ego-dimensions (ego-orientation and competence-valuation) and public self-consciousness were examined as two factors that might contribute to predicting these self-appraisals. Findings are drawn from a sample of 382 male and female high school students ranging in age from 14 to 16 years. Students responded to a questionnaire (at Time 1) that assessed self-concept, motivation orientation, competence-valuation, self-consciousness, and mathematics motivation. Teachers rated each student using a brief mathematics self-concept scale. Higher mathematics self-concept and over-rating of this self-concept were predictive of higher levels of mathematics motivation and later mathematics achievement (Time 2). Findings also indicate that ego-orientation and competence-valuation are positively associated with mathematics self-concept and over-rating, whilst public self-consciousness negatively predicts mathematics self-concept and is also associated with a tendency to under-rate oneself in this domain.

Body conscious? Interoceptive awareness, measured by heartbeat perception, is negatively correlated with self-objectification.

'Self-objectification' is the tendency to experience one's body principally as an object, to be evaluated for its appearance rather than for its effectiveness. Within objectification theory, it has been proposed that self-objectification accounts for the poorer interoceptive awareness observed in women, as measured by heartbeat perception. Our study is, we believe, the first specifically to test this relationship. Using a well-validated and reliable heartbeat perception task, we measured interoceptive awareness in women and compared this with their scores on the Self-Objectification Questionnaire, the Self-Consciousness Scale and the Body Consciousness Questionnaire. Interoceptive awareness was negatively correlated with self-objectification. Interoceptive awareness, public body consciousness and private body consciousness together explained 31% of the variance in self-objectification. However, private body consciousness was not significantly correlated with interoceptive awareness, which may explain the many nonsignificant results in self-objectification studies that have used private body consciousness as a measure of body awareness. We propose interoceptive awareness, assessed by heartbeat perception, as a measure of body awareness in self-objectification studies. Our findings have implications for those clinical conditions, in women, which are characterised by self-objectification and low interoceptive awareness, such as eating disorders.

Medial prefrontal cortex and the emergence of self-conscious emotion in adolescence

In the present study, we examined the relationship between developmental modulation of socioaffective brain systems and adolescents’ preoccupation with social evaluation. Child, adolescent, and adult participants viewed cues indicating that a camera was alternately off, warming up, or projecting their image to a peer during the acquisition of behavioral-, autonomic-, and neural-response (functional MRI) data. Believing that a peer was actively watching them was sufficient to induce self-conscious emotion that was stronger in adolescents than in children and adults. Autonomic arousal was uniquely heightened in adolescents. These behavioral patterns were paralleled by emergent engagement of the medial prefrontal cortex (MPFC) and striatum-MPFC connectivity during adolescence, which are thought to promote adolescent-motivated social behavior. These findings demonstrate that adolescents’ self-consciousness is related to age-dependent sensitivity of brain systems critical to socioaffective processes. Further, unique interactions between the MPFC and striatum may provide a mechanism by which social-evaluation contexts influence adolescent behavior. PMID:23804962

Female sexual arousal disorder is a pathophysiologic state characterized clinically by persistent or recurrent inability to attain or maintain an adequate lubrication-swelling response of sexual excitement until completion of sexual activity. Prior clinical experience with alprostadil products for men with erectile dysfunction supports its use in women with female sexual arousal disorder. To compare the effect of topical alprostadil with over-the-counter (OTC) lubricant on female genital arousal in the absence of visual sexual stimuli. Healthy premenopausal women without sexual dysfunction were recruited from the community to participate in the study. Of 17 women who consented, 10 were enrolled and completed the trial. The mean age of subjects was 32 years (range = 27-43). Study drug or placebo was applied topically to the genitals. Continuous temperature monitoring was performed. Participants completed questionnaires assessing genital sensation, effect, intensity, and duration. Change in temperature from baseline in vestibule, clitoris and vulva. In all 10 subjects, topical alprostadil induced a statistically significant increase in temperature of the vestibule, clitoris, and vulva compared with the OTC lubricant. The most rapid difference in genital temperature between placebo and alprostadil was seen on the vulva, which demonstrated a significant difference at approximately 9 minutes. There was a significant difference in temperature seen for the vestibule and clitoris at 11 and 19 minutes, respectively. Sixty percent of women reported being aware or conscious of genital sensations with topical alprostadil, but not with OTC lubricant. Discordance was noted in 30% of subjects who reported being aware or conscious of genital sensations with the two treatments and 10% who reported not being aware or conscious of genital sensations with either treatment. Topical alprostadil administered to healthy premenopausal women induced statistically significant, sustained

Clitoral reconstruction after genital mutilation is a feasible and effective strategy to reduce clitoral pain, improve sexual pleasure, and restore vulvar appearance. We describe a novel surgical technique for clitorolabial reconstruction using a vaginal graft. We present a series of 32 consecutive women who underwent this procedure at Iván Mañero Clinic, Barcelona, Spain, and were prospectively followed. The total Female Sexual Function Index changed favorably from 16 before surgery to 29 after surgery (P<.05). Likewise, the Female Self-Image Genital Scale changed favorably from 11 to 23 (P<.05). Clitoral reconstruction after genital mutilation was associated with improved sexual function and genital aesthetic perception.

Self-assessment of genital anatomy, sexual sensitivity and function in women: implications for genitoplasty.

To assess the perceptions of healthy women of their genital anatomy and sexual sensitivity, and to provide suggestions for genitoplasty based on this information, as the success of genitoplasty has historically relied upon the surgeon's perception of the patient's anatomy and function, rather than the patient's perception of outcome in terms of appearance and erotic sensitivity. Fifty healthy, sexually active, adult women (aged 20-56 years) with no history of genital surgery completed the female version of the Self-Assessment of Genital Anatomy and Sexual Function. This self- report questionnaire comprises written text and images enabling women to rate the appearance, size and position of clitoris and vagina, as well as the intensity of orgasm and effort required for achieving orgasm in specified areas around the clitoris and within the vagina. Anatomical locations were compared for these ratings by repeated-measures analysis of variance. Anatomically, 46% of women described their clitoris as 'moderate-sized and raised', 42% as 'small and raised', and 78% reported that their vaginal opening was adequate for sexual penetration. The women reported the strongest orgasm and least effort to obtain an orgasm with stimulation of the area on and above the clitoris. For vaginal sensitivity, scores for orgasm intensity increased, and for orgasm effort decreased, with increasing vaginal depth, and they indicated less sexual sensitivity for the vagina than for the external genitalia. The skin above the clitoris, and the clitoris itself, appeared to be the most sexually sensitive. During genitoplasty, attention to preserving skin-flap integrity in this area seems appropriate.

Intuitive Intelligence, Self-regulation, and Lifting Consciousness

Zayas, Maria

2014-01-01

This article explores the role of the heart in emotional experience, as well as how learning to shift the rhythms of the heart into a more coherent state makes it possible to establish a new inner baseline reference that allows access to our heart’s intuitive capacities and deeper wisdom. The nature and types of intuition and the connection between intuition and compassionate action are discussed. It is suggested that increased effectiveness in self-regulatory capacity and the resultant reorganization of memories sustained in the neural architecture facilitates a stable and integrated experience of self in relationship to others and to the environment, otherwise known as consciousness. The implications of meeting the increasingly complex demands of life with greater love, compassion, and kindness, thereby lifting consciousness, are considered. PMID:24808982

The consciousness state space (CSS)—a unifying model for consciousness and self

PubMed Central

Berkovich-Ohana, Aviva; Glicksohn, Joseph

2014-01-01

Every experience, those we are aware of and those we are not, is embedded in a subjective timeline, is tinged with emotion, and inevitably evokes a certain sense of self. Here, we present a phenomenological model for consciousness and selfhood which relates time, awareness, and emotion within one framework. The consciousness state space (CSS) model is a theoretical one. It relies on a broad range of literature, hence has high explanatory and integrative strength, and helps in visualizing the relationship between different aspects of experience. Briefly, it is suggested that all phenomenological states fall into two categories of consciousness, core and extended (CC and EC, respectively). CC supports minimal selfhood that is short of temporal extension, its scope being the here and now. EC supports narrative selfhood, which involves personal identity and continuity across time, as well as memory, imagination and conceptual thought. The CSS is a phenomenological space, created by three dimensions: time, awareness and emotion. Each of the three dimensions is shown to have a dual phenomenological composition, falling within CC and EC. The neural spaces supporting each of these dimensions, as well as CC and EC, are laid out based on the neuroscientific literature. The CSS dynamics include two simultaneous trajectories, one in CC and one in EC, typically antagonistic in normal experiences. However, this characteristic behavior is altered in states in which a person experiences an altered sense of self. Two examples are laid out, flow and meditation. The CSS model creates a broad theoretical framework with explanatory and unificatory power. It constructs a detailed map of the consciousness and selfhood phenomenology, which offers constraints for the science of consciousness. We conclude by outlining several testable predictions raised by the CSS model. PMID:24808870

Predictors of Biased Self-perception in Individuals with High Social Anxiety: The Effect of Self-consciousness in the Private and Public Self Domains.

PubMed

Nordahl, Henrik; Plummer, Alice; Wells, Adrian

2017-01-01

"Biased self-perception," the tendency to perceive one's social performance as more negative than observers do, is characteristic of socially anxious individuals. Self-attention processes are hypothesised to underlie biased self-perception, however, different models emphasise different aspects of self-attention, with attention to the public aspects of the self being prominent. The current study aimed to investigate the relative contribution of two types of dispositional self-attention; public- and private self-consciousness to biased self-perception in a high ( n = 48) versus a low ( n = 48) social anxiety group undergoing an interaction task. The main finding was that private self-consciousness explained substantial and unique variance in biased negative self-perception in individuals with high social anxiety, while public self-consciousness did not. This relationship was independent of increments in state anxiety. Private self-consciousness appeared to have a specific association with bias related to overestimation of negative social performance rather than underestimation of positive social performance. The implication of this finding is that current treatment models of Social anxiety disorder might include broader aspects of self-focused attention, especially in the context of formulating self-evaluation biases.

Prominent theories highlight the importance of bodily perception for self-consciousness, but it is currently not known whether this is based on interoceptive or exteroceptive signals or on integrated signals from these anatomically distinct systems, nor where in the brain such integration might occur. To investigate this, we measured brain activity during the recently described 'cardio-visual full body illusion' which combines interoceptive and exteroceptive signals, by providing participants with visual exteroceptive information about their heartbeat in the form of a periodically illuminated silhouette outlining a video image of the participant's body and flashing in synchrony with their heartbeat. We found, as also reported previously, that synchronous cardio-visual signals increased self-identification with the virtual body. Here we further investigated whether experimental changes in self-consciousness during this illusion are accompanied by activity changes in somatosensory cortex by recording somatosensory evoked potentials (SEPs). We show that a late somatosensory evoked potential component (P45) reflects the illusory self-identification with a virtual body. These data demonstrate that interoceptive and exteroceptive signals can be combined to modulate activity in parietal somatosensory cortex.

The brain network reflecting bodily self-consciousness: a functional connectivity study

PubMed Central

Ionta, Silvio; Martuzzi, Roberto; Salomon, Roy

Several brain regions are important for processing self-location and first-person perspective, two important aspects of bodily self-consciousness. However, the interplay between these regions has not been clarified. In addition, while self-location and first-person perspective in healthy subjects are associated with bilateral activity in temporoparietal junction (TPJ), disturbed self-location and first-person perspective result from damage of only the right TPJ. Identifying the involved brain network and understanding the role of hemispheric specializations in encoding self-location and first-person perspective, will provide important information on system-level interactions neurally mediating bodily self-consciousness. Here, we used functional connectivity and showed that right and left TPJ are bilaterally connected to supplementary motor area, ventral premotor cortex, insula, intraparietal sulcus and occipitotemporal cortex. Furthermore, the functional connectivity between right TPJ and right insula had the highest selectivity for changes in self-location and first-person perspective. Finally, functional connectivity revealed hemispheric differences showing that self-location and first-person perspective modulated the connectivity between right TPJ, right posterior insula, and right supplementary motor area, and between left TPJ and right anterior insula. The present data extend previous evidence on healthy populations and clinical observations in neurological deficits, supporting a bilateral, but right-hemispheric dominant, network for bodily self-consciousness.

The body, its emotions, the self, and consciousness.

PubMed

Boyd, Graham W

2012-01-01

This article proposes a means for better understanding the self and consciousness. Data indicate that the basic "emotional brain" continually computes potential survival risk against reward to rank consequent "emotion scores" for all sensory inputs. These scores compete to yield winner-takes-all outcomes that determine the choice of attention or action. This mechanism prevails regardless of whether the competing options gain their emotion scores through a rational or an intuitive pathway. There is no need to postulate any homunculus or inner self in control of such choice; indeed, our belief in a first-person self in overall control is wrong. The self is a passive construct arising from each individual's social development, where language acquisition vastly heightens communication and awareness not only outwardly, but also inwardly, as if to a controlling "inner I." However, when society comes to hold the maturing being accountable for his or her actions, the brain must respond, and it does so in the only way it can, by deeming that this passive, inner self-construct act as if it were the active self in charge. Consciousness emerges when the language-based output of the higher brain is referred for ownership to this artificial self-construct.

Triggers of self-conscious emotions in the sexually transmitted infection testing process

PubMed Central

2010-01-01

Background Self-conscious emotions (shame, guilt and embarrassment) are part of many individuals' experiences of seeking STI testing. These emotions can have negative impacts on individuals' interpretations of the STI testing process, their willingness to seek treatment and their willingness to inform sexual partners in light of positive STI diagnoses. Because of these impacts, researchers have called for more work to be completed on the connections between shame, guilt, embarrassment and STI testing. We examine the specific events in the STI testing process that trigger self-conscious emotions in young adults who seek STI testing; and to understand what it is about these events that triggers these emotions. Semi-structured interviews with 30 adults (21 women, 9 men) in the Republic of Ireland. Findings Seven specific triggers of self-conscious emotions were identified. These were: having unprotected sex, associated with the initial reason for seeking STI testing; talking to partners and peers about the intention to seek STI testing; the experience of accessing STI testing facilities and sitting in clinic waiting rooms; negative interactions with healthcare professionals; receiving a positive diagnosis of an STI; having to notify sexual partners in light of a positive STI diagnosis; and accessing healthcare settings for treatment for an STI. Self-conscious emotions were triggered in each case by a perceived threat to respondents' social identities. Conclusion There are multiple triggers of self-conscious emotions in the STI testing process, ranging from the initial decision to seek testing, right through to the experience of accessing treatment. The role of self-conscious emotions needs to be considered in each component of service design from health promotion approaches, through facility layout to the training of all professionals involved in the STI testing process.

I.P. Pavlov considered consciousness as an area of optimum excitability moving over the human cerebral cortex depending on the character of performed mental activity. Contemporary methods of computer analysis of electrical activity and brain thermal production have allowed to turn this metaphor into experimentally observed reality. It is shown that preservation of connections of cortical gnostic zones with verbal structures of the left hemisphere is the obligatory condition for consciousness functioning. These data reinforce the determination of consciousness as operation with knowledge, which by means of words, mathematic symbols and art images can be transmitted to other people. Communicative origin of consciousness creates possibility of mental dialogue with oneself, i.e. leads to the appearance of self-consciousness of the personality.

Davidson, Denise; Vanegas, Sandra B; Hilvert, Elizabeth

2017-11-01

Self-conscious emotions, such as shame, guilt and pride, facilitate our social interactions by motivating us to adhere to social norms and external standards. In this study, we examined proneness to shame, guilt, hubristic pride and authentic pride in adults with Autism Spectrum Disorder traits (ASD-T) and in neurotypical (NT) adults. Relations between proneness to self-conscious emotions and theory of mind (ToM), fear of negative evaluation, and social functioning were also assessed. Adults with ASD-T showed greater proneness to shame, and less proneness to guilt and pride than NT adults. Both ToM and fear of negative evaluation predicted proneness to self-conscious emotions in ASD-T. These findings are discussed in terms of understanding complex emotion processing in adults with ASD-T.

Objectives To evaluate the relationship of warts in different parts of the body and the risk of asymptomatic genital human papillomavirus (HPV) infection in men. Methods We examined the relationship of self-reported genital and extra-genital warts with the subsequent acquisition of asymptomatic genital HPV infection in a cohort of 331 adult men. Participants were followed at 2-month intervals for up to 4 years. Past and current presence of warts was queried at study entry. At each visit, the external genitals were sampled for HPV DNA testing. Results Men who reported a history of genital warts, including current warts, were at increased risk of acquisition of asymptomatic HPV infection of the penis glans/corona, penis shaft and scrotum. The magnitude of these associations was greatest for HPV 6/11 infection. History of warts on the fingers, arms and trunk of the body was also associated with increased risk of genital HPV infection. Current presence of warts on the fingers and trunk specifically increased the risk of acquisition of HPV types not typically found on the genitals. Conclusions Men with a history of warts on the genitals, fingers, arms and trunk may be at increased risk for acquisition of new genital HPV infections. Warts may provide an efficient reservoir for the transmission of virions to the genitals through auto-inoculation. The potential for the spread of HPV throughout the body through auto-inoculation has important implications for prevention and control of HPV infection. PMID:21602516

Self-conscious affects: their adaptive Functions and relationship to depressive mood.

This study used a structural equation model to examine the influence of resilience on the four self-conscious affects (guilt-proneness, shame-proneness, externalization, and detachment) assessed in the Test of Self-Conscious Affect-3 (TOSCA-3) and their impact on depressive mood. Our subject population consisted of 447 Japanese university students. The first analysis explored which TOSCA-3 affects help an individual adapt to stressful situations. The concept of "resilience" was used as an indicator to evaluate the adaptive functions. We based this on the assumption that an individual with higher resilience is able to use more adaptive affects. In the second analysis, taking the above relationship between resilience and the self-conscious affects into consideration, we examined how those variables as well as a negative life event are related to depressive mood. To assess the resilience level and depressive mood, we adopted the Resilience Scale (RS) and Self-rating Depressive Scale (SDS), respectively. The first analysis showed that the more resilient an individual was, the more prone they were to "detachment" and the less "shame" they experienced. The level of resilience did not have a significant effect on "guilt" or "externalization." In the second analysis we found that "resilience" had a direct inverse effect on depressive mood that was also mediated by "shame" and "detachment." We discuss how the particular self-conscious affects comprising each adaptive function are related to depressive mood.

Unconscious integration of multisensory bodily inputs in the peripersonal space shapes bodily self-consciousness.

2017-09-01

Recent studies have highlighted the role of multisensory integration as a key mechanism of self-consciousness. In particular, integration of bodily signals within the peripersonal space (PPS) underlies the experience of the self in a body we own (self-identification) and that is experienced as occupying a specific location in space (self-location), two main components of bodily self-consciousness (BSC). Experiments investigating the effects of multisensory integration on BSC have typically employed supra-threshold sensory stimuli, neglecting the role of unconscious sensory signals in BSC, as tested in other consciousness research. Here, we used psychophysical techniques to test whether multisensory integration of bodily stimuli underlying BSC also occurs for multisensory inputs presented below the threshold of conscious perception. Our results indicate that visual stimuli rendered invisible through continuous flash suppression boost processing of tactile stimuli on the body (Exp. 1), and enhance the perception of near-threshold tactile stimuli (Exp. 2), only once they entered PPS. We then employed unconscious multisensory stimulation to manipulate BSC. Participants were presented with tactile stimulation on their body and with visual stimuli on a virtual body, seen at a distance, which were either visible or rendered invisible. We found that participants reported higher self-identification with the virtual body in the synchronous visuo-tactile stimulation (as compared to asynchronous stimulation; Exp. 3), and shifted their self-location toward the virtual body (Exp.4), even if stimuli were fully invisible. Our results indicate that multisensory inputs, even outside of awareness, are integrated and affect the phenomenological content of self-consciousness, grounding BSC firmly in the field of psychophysical consciousness studies.

2011-12-01

With the patient's consent, physical injuries sustained in a sexual assault are evaluated and treated by the sexual assault nurse examiner (SANE) and documented on preprinted traumagrams and with photographs. Digital imaging is now available to the SANE for documentation of sexual assault injuries, but studies of the image quality of forensic digital imaging of female genital injuries after sexual assault were not found in the literature. The Photo Documentation Image Quality Scoring System (PDIQSS) was developed to rate the image quality of digital photo documentation of female genital injuries after sexual assault. Three expert observers performed evaluations on 30 separate images at two points in time. An image quality score, the sum of eight integral technical and anatomical attributes on the PDIQSS, was obtained for each image. Individual image quality ratings, defined by rating image quality for each of the data, were also determined. The results demonstrated a high level of image quality and agreement when measured in all dimensions. For the SANE in clinical practice, the results of this study indicate that a high degree of agreement exists between expert observers when using the PDIQSS to rate image quality of individual digital photographs of female genital injuries after sexual assault. © 2011 International Association of Forensic Nurses.

The current study examined whether exposure to sexually objectifying images in a potential romantic partner's virtual apartment affects discrepancies between people's perception of their own appearance (i.e., self-perceptions) and their perception of the body ideal that is considered desirable to a romantic partner (i.e., partner-ideals). Participants were 114 heterosexual undergraduate students (57 women and 57 men) from a northeastern U.S. university. The study used a 2 (Participant Gender) x 2 (Virtual Environment: Sexualized vs. Non-Sexualized) between-subjects design. We predicted that women exposed to sexually objectifying images in a virtual environment would report greater discrepancies between their self-perceptions and partner-ideals than men, which in turn would contribute to women's body consciousness. Findings support this hypothesis and show that perceived discrepancies account for the relationship between exposure to sexually objectifying images and body consciousness for women but not men. We also found gender asymmetries in objectification responses when each component of perceived discrepancies, i.e., self-perceptions versus perceptions of a romantic partner's body ideal, were examined separately. For men, exposure to muscular sexualized images was significantly associated with their self-perceptions but not their perceptions of the body size that is considered desirable to a romantic partner. For women, exposure to thin sexualized images was significantly associated with their perceptions that a romantic partner preferred a woman with a smaller body size. However, exposure to these images did not affect women's self-perceptions. Implications for gender asymmetries in objectification responses and perceived discrepancies that include a romantic partner's perceptions are discussed. PMID:26594085

Genital warts are one of the most common forms of sexually-transmitted disease, but their epidemiology has yet to be thoroughly elucidated. The present study was designed to shed light on the prevalence of clinically-confirmed, self-reported genital warts (GWs) in a representative sample of the university population. In 2015, a cross-sectional survey was conducted on 11,096 individuals approached at the Students Information Bureau where they came to enroll for a university degree course. Participants completed an anonymous, self-administered questionnaire providing information on their sociodemographic characteristics, sexual behavior, and any history of clinically-diagnosed genital warts. Multivariate logistic regression was then used to identify any factors associated with the disease. Our analysis was conducted on 9259 questionnaires (83.4%). Participants were a mean 21.8 ± 4.8 years of age, and 59.6% were female. Overall, 124 individuals (1.3%, 95%CI: 1.0-1.6) reported having been diagnosed with genital warts: 48 men (1.3%, 95%CI: 0.9-1.6), and 76 women (1.4% 95%CI: 1.1-1.7). Overall, 22.5% of the sample were vaccinated (1.3% of the males and 36.8% of the females). The group of respondents aged 30 years or more had the highest incidence of genital warts (males: 5.6%, 95%CI: 2.5-8.6; females: 6.9%, 95%CI: 3.4-10.4). The independent risk factors associated with a history of disease were (for both genders) a history of other sexually-transmitted diseases, and ≥2 sex partners in the previous 24 months. A protective role emerged for routine condom use. Additional risk factors associated with genital warts in males concerned men who have sex with men, bisexuality vis-à-vis heterosexuality, and smoking. The findings emerging from our study help to further clarify the epidemiology of genital warts in young people, and may be useful to public health decision-makers. This study showed that genital warts occur in men as well as women, and suggests that both

Paradigm shift in consciousness research: the child's self-awareness and abnormalities in autism, ADHD and schizophrenia.

PubMed

Lou, Hans C

Self-awareness is a pivotal component of any conscious experience and conscious self-regulation of behaviour. A paralimbic network is active, specific and causal in self-awareness. Its regions interact by gamma synchrony. Gamma synchrony develops throughout infancy, childhood and adolescence into adulthood and is regulated by dopamine and other neurotransmitters via GABA interneurons. Major derailments of this network and self-awareness occur in developmental disorders of conscious self-regulation like autism, attention deficit hyperactivity disorder (ADHD) and schizophrenia. Recent research on conscious experience is no longer limited to the study of neural 'correlations' but is increasingly lending itself to the study of causality. This paradigm shift opens new perspectives for understanding the neural mechanisms of the developing self and the causal effects of their disturbance in developmental disorders. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

Investing in the ideal: does objectified body consciousness mediate the association between appearance contingent self-worth and appearance self-esteem in women?

PubMed

Noser, Amy; Zeigler-Hill, Virgil

2014-03-01

Appearance contingent self-worth has been shown to be associated with low appearance self-esteem but little is known about the role that objectified body consciousness may play in this relationship. The purpose of the present study with 465 female undergraduates was to examine whether objectified body consciousness mediates the association between appearance contingent self-worth and low levels of appearance self-esteem. This was accomplished using a multiple mediation model to examine whether components of objectified body consciousness (i.e., body surveillance, body shame, and control beliefs) play unique roles in the connection between appearance contingent self-worth and appearance self-esteem. Results showed that body surveillance and body shame were significant mediators of the connection between appearance contingent self-worth and low levels of appearance self-esteem. Discussion focuses on the implications of these results for the ways in which appearance contingent self-worth may promote heightened body consciousness and possibly contribute to low levels of appearance self-esteem.

Background Research has highlighted the complex association between female sexual dysfunction (FSD) and distress regarding sexual activity, with decreased physical pleasure being an important mediator. The current study aims to elucidate the association between pleasurable and painful genital sensitivity and FSD, and to further investigate whether FSD may be distressing because it prevents the experience of sexual pleasure, induces pain or both. Sexually active women (n=256; median, 22 years; range, 18-49 years) completed web-based questionnaires, including the Self-Assessment of Genital Anatomy and Sexual Function, the Female Sexual Function Index and the Female Sexual Distress Scale. Women reported their clitoris to be more sensitive than their vagina in terms of having more pleasurable responses (P<0.001), but not more painful responses (P=0.49). In women with FSD (n=36), impaired self-perceived genital sensation was found: they reported significantly less sexual pleasure and orgasm intensity, and more orgasm effort and discomfort within the clitoral and vaginal area than women without FSD (n=220) (P-value<0.05). The odds of having FSD were significantly greater in women with perceived increased discomfort in the vaginal area during stimulation (odds ratio=5.59, P=0.009, 95% confidence interval: 1.53-20.39), but not in the clitoral area. The data provide evidence of the relevance of self-perceived genital sensitivity to sexual pleasure and overall sexual experience. Enhancing the pleasurableness of genital sensations, especially during partnered sex, could decrease the likelihood of experiencing pain and concomitant FSD.

As science continues to explore the mysteries of the unconscious, two critical questions remain. First, can unconscious impulses, desires, and feelings be willfully raised to the level of the conscious self?, and, if so, would the unveiling of unconscious mechanisms lead to genuine self-knowledge or empowerment? Second, can we methodically tap into the unconscious to gear ourselves along more creative lines? If the unconscious is a source of intuitive and creative inspiration, how might a more expansive understanding of consciousness help us to flourish? How can we harness the intuitive parts of ourselves to think "outside the box," transcending the limitations of preconceived categories? And along those same lines, how would an expanded view of the unconscious frame our spiritual experiences or offer spiritual nourishment? Writer Siri Hustvedt, historian of psychology Sonu Shamdasani, and neuropsychologist Mark Solms will tackle everything from noetic experiences and the role of intuition to the phenomenon of peak experience and Jung's "collective unconscious." © 2017 New York Academy of Sciences.

Handedness and the fringe of consciousness: strong handers ruminate while mixed handers self-reflect.

PubMed

Niebauer, Christopher Lee

2004-12-01

Previous research found that mixed handers (i.e., those that are more ambidextrous) were more likely than strong handers to update their beliefs (Niebauer, Aselage, & Schutte, 2002). It was assumed that this was due to greater degrees of communication between the two cerebral hemispheres in mixed handers. Niebauer and Garvey (2004) made connections between this model of updating beliefs and metacognitive processing. The current work proposes that variations in interhemispheric interaction (as measured by degree of handedness) contribute to differences in consciousness, specifically when consciousness is used in rumination versus the metacognitive task of self-reflection. Using the Rumination-Reflection Questionnaire (Trapnell & Campbell, 1999), predictions were supported such that strong handedness was associated with self-rumination; whereas, mixed handedness was associated with increased self-reflection p values<.01, (N=255). James's (1890) concept of the "fringe of consciousness" is used to make connections between metacognition, updating beliefs, and self-reflection. Several studies are reviewed suggesting that mixed handers experience fringe consciousness to a greater degree than strong handers.

We have developed a SPECT imaging system, AwakeSPECT, to enable molecular brain imaging of untrained mice that are conscious, unanesthetized, and unrestrained. We accomplished this with head tracking and motion correction techniques. Methods: The capability of the system for motion-corrected imaging was demonstrated with a 99mTc-pertechnetate phantom, 99mTcmethylene diphosphonate bone imaging, and measurement of the binding potential of the dopamine transporter radioligand 123I-ioflupane in mouse brain in the awake and anesthetized (isoflurane) states. Stress induced by imaging in the awake state was assessed through measurement of plasma corticosterone levels. Results: AwakeSPECT provided high-resolution bone images reminiscent of those obtained frommore » CT. The binding potential of 123I-ioflupane in the awake state was on the order of 50% of that obtained with the animal under anesthesia, consistent with previous studies in nonhuman primates. Levels of stress induced were on the order of those seen in other behavioral tasks and imaging studies of awake animals. Conclusion: These results demonstrate the feasibility of SPECT molecular brain imaging of mice in the conscious, unrestrained state and demonstrate the effects of isoflurane anesthesia on radiotracer uptake.« less

The effects of private self-consciousness and perspective taking on satisfaction in close relationships.

PubMed

Franzoi, S L; Davis, M H; Young, R D

1985-06-01

We extended the scope of recent studies in which self-awareness and perspective taking have been used as predictors of social competence or adjustment: We analyzed their influence on the satisfaction experienced in monogamous, heterosexual relationships. Members of 131 couples answered questions concerning themselves and their relationships. We predicted that individual differences in private self-consciousness would be positively related to relationship satisfaction because of the greater self-disclosure resulting from that heightened self-attention. Second, we predicted that individual differences in perspective taking would foster relationship satisfaction, independent of any influence of self-disclosure. Both expectations were confirmed. Scores on the private self-consciousness scale were predictive of reported self-disclosure, and self-disclosure was predictive of satisfaction in the relationship. Furthermore, once the influence of self-disclosure was removed, no effect of self-consciousness on satisfaction remained. In contrast, after disclosure was controlled, perspective-taking scores were significantly related to satisfaction and were in fact unrelated to disclosure at all. These findings indicate that two personality characteristics having to do with habitual attention to behavioral tendencies, to emotions, and to motivations significantly enhance the quality of close heterosexual relationships in different ways. Results are discussed in terms of current theory in the related fields.

Neural correlates of consciousness: what we know and what we have to learn!

2015-04-01

Consciousness is a multifaceted concept with two major components: awareness of environment and of self (i.e., the content of consciousness) and wakefulness (i.e., the level of consciousness). Medically speaking, consciousness is the state of the patient's awareness of self and environment and his responsiveness to external stimulation and inner need. A basic understanding of consciousness and its neural correlates is of major importance for all clinicians, especially those involved with patients suffering from altered states of consciousness. To this end, in this review it is shown that consciousness is dependent on the brainstem and thalamus for arousal; that basic cognition is supported by recurrent electrical activity between the cortex and the thalamus at gamma band frequencies; and that some kind of working memory must, at least fleetingly, be present for awareness to occur. New advances in neuroimaging studies are also presented in order to better understand and demonstrate the neurophysiological basis of consciousness. In particular, recent functional magnetic resonance imaging studies have offered the possibility to measure directly and non-invasively normal and severely brain damaged subjects' brain activity, whilst diffusion tensor imaging studies have allowed evaluating white matter integrity in normal subjects and patients with disorder of consciousness.

Implications of Genital Mutilation at Autopsy.

PubMed

Byard, Roger W

2017-07-01

Given the potential significance of mutilation of the external genitalia in medicolegal fatalities, a review of the literature was undertaken to identify subcategories. Such mutilations may have been sustained sometime before death, around the time of death, or after death. The most common type of ante mortem genital mutilations involves cultural practices such as male circumcision. Less common male mutilations such as subincisions are tribally based. Female genital mutilation is found particularly in African, Middle Eastern, or Asian populations. Self-inflicted genital injuries are most common in males and may be related to attempts at suicide, or to self-harming practices. The latter have a strong association with psychiatric illnesses. Postmortem injuries may arise from animal predation or deliberate mutilation of a corpse. The latter may be associated with ante mortem genital injuries in sadistic homicides. The range of possible causes of genital mutilations in forensic cases necessitates extremely careful evaluation. © 2017 American Academy of Forensic Sciences.

The Actual and Ideal Sexual Self Concept in the Context of Genital Pain Using Implicit and Explicit Measures.

2017-05-01

The experience of pain during sexual intercourse generates significant distress and sexual impairments, which is likely to affect sexual identity and become a threat to the sense of self. To explore the role of the concept of the sexual self in the context of genital pain by measuring different states of self (ie, actual vs ideal) at different levels of responding (ie, explicit vs implicit) and examine their associations with sexual, emotional, and pain-related variables. Thirty young women who identified with genital pain and 29 women without pain completed (i) two versions of the Relational Responding Task as a measurement of implicit actual and ideal sexual self; (ii) explicit ratings of the actual and the ideal sexual self; and (iii) measurements of sexual self-esteem, global self-esteem, depression, sexual satisfaction, sexual distress or depression, sexual frequency, and pain experiences. Women with genital pain scored lower on the explicit and implicit actual-self measurements than women without pain but did not differ in their ideal self. Furthermore, the pain group reported higher ideal- than actual-self scores at the explicit level. Actual- and ideal-self measurements had differential effects on sexual, emotional, and behavioral outcome variables. In general, rating the ideal self higher than the actual self was related to more negative outcomes. Pain-related variables were predicted only by the implicit measurements, showing that the high pain group reported more pain, fear of pain, and a stronger tendency to continue with sex despite the pain when perceiving themselves as sexually less competent and when this perception did not match their ideal self. Therapeutic interventions might benefit from discussing women's internal guides for self, decreasing potential discrepancies, and developing identity-related motivational treatments that target the emotional discomfort and maladaptive behavioral strategies that result from trying to conform with their

Data on self-perceived genital anatomy and sensitivity should be part of the long-term follow-up of genitoplasty procedures. However, no normative data, based on a large sample, exist to date. Validation of the Self-Assessment of Genital Anatomy and Sexual Function, Female version (SAGAS-F) questionnaire within a Belgian, Dutch-speaking female population. Seven hundred forty-nine women with no history of genital surgery (aged 18-69 years, median 25 years) completed an Internet-based survey of whom 21 women underwent a gynecological examination as to correlate self-reported genital sensitivity assessed in an experimental setting. The SAGAS-F enables women to rate the sexual pleasure, discomfort, intensity of orgasm, and effort required for achieving orgasm in specified areas around the clitoris and within the vagina, as well as genital appearance. The latter was similarly evaluated by an experienced gynecologist, and women were asked to functionally rate the anatomical areas pointed out with a vaginal swab. Sexual pleasure and orgasm were strongest, and effort to attain orgasm and discomfort was lowest when stimulating the clitoris and sides of the clitoris (P < 0.05). Vaginal sensitivity increased with increasing vaginal depth, but overall orgasmic sensitivity was lower as compared with the clitoris. Functional scores on the SAGAS-F and during gynecological examination corresponded highly on most anatomical areas (P < 0.05). Gynecologist's ratings corresponded highly with the women's ratings for vaginal size (90%) but not for clitoral size (48%). Replication of the original pilot study results support the validity of the questionnaire. The SAGAS-F discriminates reasonably well between various genital areas in terms of erotic sensitivity. The clitoris itself appeared to be the most sensitive, consistent with maximum nerve density in this area. Surgery to the clitoris could disrupt neurological pathways and compromise erotic sensation and pleasure. © 2013

2012-09-01

The aim of this study was to examine the associations between women's actual:ideal weight-related self-discrepancies and experiences of weight-related shame, guilt, and authentic pride using self-discrepancy (Higgins, 1987) and self-conscious emotion (Tracy & Robins, 2004) theories as guiding frameworks. Participants (N=398) completed self-report questionnaires. Main analyses involved polynomial regressions, followed by the computation and evaluation of response surface values. Actual and ideal weight self-states were related to shame (R2 = .35), guilt (R2 = .25), and authentic pride (R2 = .08). When the discrepancy between actual and ideal weights increased, shame and guilt also increased, while authentic pride decreased. Findings provide partial support for self-discrepancy theory and the process model of self-conscious emotions. Experiencing weight-related self-discrepancies may be important cognitive appraisals related to shame, guilt, and authentic pride. Further research is needed exploring the relations between self-discrepancies and a range of weight-related self-conscious emotions. Copyright © 2012 Elsevier Ltd. All rights reserved.

Genital image, sexual anxiety, and erectile dysfunction among young male military personnel.

More than a third of young military personnel report experiencing some level of erectile dysfunction (ED). Preoccupation with body image, particularly genitals, is a distraction that can influence sexual anxiety (SA) and sexual functioning problems (SFPs), particularly ED. This study assessed the relationships between male genital self-image (MGSI), SA, and ED in a sample of male military personnel age 40 or younger. Data were from a larger study on SFPs in military populations. This sample consisted of 367 male military personnel age 40 or younger. Hierarchical regression analyses and process modeling using mediation analysis were performed to examine the effects of MGSI on ED with SA as an intermediate variable. We predicted that SA would mediate the relationship between MGSI and ED. ED severity was assessed with the International Index of Erectile Function. MGSI was assessed using the MGSI Scale. SA was assessed with the SA subscale of the Sexual Needs Scale. As hypothesized, greater satisfaction with MGSI was predictive of significantly lower SA (F[8, 352] = 4.07, P = 0.001) and lower ED (F[8, 352] = 13.20, P = 0.001). Lower levels of SA were predictive of lower levels of ED (F[8, 354] = 21.35, P < 0.001). Additionally, results also revealed a significant indirect effect of MGSI on ED through SA (b = -0.07, standard error = 0.03, confidence interval = [-0.14,-0.02], P < 0.05), indicating mediation of MGSI on ED via SA. This study underscores the complex etiologic basis of SFPs, particularly ED, and highlights the importance of considering psychologic contributors to ED, such as SA and MGSI. Strategies aimed at reducing SA may be useful in improving ED in young military populations and are worth considering as complements to strategies that improve SFPs. © 2015 International Society for Sexual Medicine.

The aim of this study was to examine the associations between the body-related self-conscious emotions of shame, guilt, and pride and physical activity motivation and behavior among adult males. Specifically, motivation regulations (external, introjected, indentified, intrinsic) were examined as possible mediators between each of the body-related self-conscious emotions and physical activity behavior. A cross-sectional study was conducted with adult men (N = 152; Mage = 23.72, SD = 10.92 years). Participants completed a questionnaire assessing body-related shame, guilt, authentic pride, hubristic pride, motivational regulations, and leisure-time physical activity. In separate multiple mediation models, body-related shame was positively associated with external and introjected regulations and negatively correlated with intrinsic regulation. Guilt was positively linked to external, introjected, and identified regulations. Authentic pride was negatively related to external regulation and positively correlated with both identified and intrinsic regulations and directly associated with physical activity behavior. Hubristic pride was positively associated with intrinsic regulation. Overall, there were both direct and indirect effects via motivation regulations between body-related self-conscious emotions and physical activity (R(2) shame = .15, guilt = .16, authentic pride = .18, hubristic pride = .16). These findings highlight the importance of targeting and understanding self-conscious emotions contextualized to the body and links to motivation and positive health behavior among men. © The Author(s) 2014.

A relatively large proportion of patients with Crohn disease (CD) develop complications including abscess formation, stricture, and penetrating disease. A subset of patients will have genital and reproductive organ involvement of CD, resulting in significant morbidity. These special circumstances create unique management challenges that must be tailored to the activity, location, and extent of disease. Familiarity with the epidemiology, pathogenesis, imaging features, and treatment strategies for patients with genital CD can aid imaging diagnoses and guide appropriate patient management. The purpose of this study is to illustrate the spectrum of CD in the genital tract and reproductive organs and discuss the complex management strategies in these patients as it relates to imaging. Given the impact on patient outcome and treatment planning, familiarity with the epidemiology, pathogenesis, imaging features, and treatment of patients with genital Crohn disease can aid radiologic diagnoses and guide appropriate patient management.

Background This study aimed to estimate the prevalence of genital warts in Taiwan among those seeking healthcare, as well as genital-warts-related healthcare resource use and costs, and self-reported genital-warts-related psychosocial impact. Genital warts prevalence estimates were extracted from a daily record of patients examined from 31 October 2011 to 4 May 2012 by 67 physicians in Taiwan. Physicians recorded the total number of patients and genital warts patients seen daily for 2 weeks. These physicians also completed a survey regarding healthcare resource use, treatment, follow-up care, and referral patterns. Patient psychosocial impact was estimated using a self-administered survey. The overall prevalence of genital warts in Taiwan was estimated at 1.1%, with a higher prevalence among men. A total of 146 genital warts case patients were included in the study (76 men, 70 women). Median costs for diagnosis and treatment were US$222 for male and US$351.8 for female patients. Male genital warts subjects reported a negative psychosocial impact on their well-being and health-related quality of life - psychosocial impact results are reported in the Supplementary Material file. Genital warts prevalence was higher among male patients; female patients incurred higher costs. Among men, genital warts had a negative psychosocial impact on well-being and health-related quality of life.

Genital herpes simplex virus infections.

PubMed

Rosenthal, M S

1979-09-01

In recent years, a great increase in interest in genital herpes has been stimulated partly by the rising prevalence of this disease and partly by observations suggesting that genital herpes is a cause of cervical cancer. The clinical pictures produced by genital herpes simplex virus infections are similar in men and women. In contrast to recurrent attacks, initial episodes of infection are generally more extensive, last longer, and are more often associated with regional lymphadenopathy and systemic symptoms. Genital herpes in pregnancy may pose a serious threat to the newborn infant. Although the data suggesting genital herpes simplex virus infection is a cause of cervical cancer are quite extensive, the evidence is largely circumstantial. In spite of these more serious aspects of genital herpes simplex virus infection, episodes of genital herpes are almost always self-limited and benign. Frequent recurrences pose the major therapeutic and management problem. At present, there is no satisfactory treatment for recurrent genital herpes simplex virus in fection. Many of the suggested therapies, although some sound very promising, are potentially dangerous and should be used only under carefully controlled conditions.

Current Concepts for Genital Herpes Simplex Virus Infection: Diagnostics and Pathogenesis of Genital Tract Shedding

PubMed Central

Corey, Lawrence

2015-01-01

SUMMARY Herpes simplex virus 2 (HSV-2) is a DNA virus that is efficiently transmitted through intimate genital tract contact and causes persistent infection that cannot be eliminated. HSV-2 may cause frequent, symptomatic self-limited genital ulcers, but in most persons infection is subclinical. However, recent studies have demonstrated that the virus is frequently shed from genital surfaces even in the absence of signs or symptoms of clinical disease and that the virus can be transmitted during these periods of shedding. Furthermore, HSV-2 shedding is detected throughout the genital tract and may be associated with genital tract inflammation, which likely contributes to increased risk of HIV acquisition. This review focuses on HSV diagnostics, as well as what we have learned about the importance of frequent genital HSV shedding for (i) HSV transmission and (ii) genital tract inflammation, as well as (iii) the impact of HSV-2 infection on HIV acquisition and transmission. We conclude with discussion of future areas of research to push the field forward. PMID:26561565

The self-conscious emotions of guilt, shame, and pride typically occur when people evaluate their own self through the eyes of another person. This article will first of all discuss the nature and function of self-conscious emotions, and describe their developmental course in children and adolescents. Then, a number of variables are discussed that are thought to increase young people's proneness to experience self-conscious emotions. Following this, the empirical evidence on the relationships between guilt, shame, and pride and various types of psychopathology in children and adolescents will be summarized. A model is presented to explain why these self-conscious emotions are associated with a diversity of psychopathological outcomes. Finally, recommendations for clinical practice are made in terms of assessment and interventions targeting the origins and sequelae of self-conscious emotions.

Xenomelia: a social neuroscience view of altered bodily self-consciousness.

Xenomelia, the "foreign limb syndrome," is characterized by the non-acceptance of one or more of one's own extremities and the resulting desire for elective limb amputation or paralysis. Formerly labeled "body integrity identity disorder" (BIID), the condition was originally considered a psychological or psychiatric disorder, but a brain-centered Zeitgeist and a rapidly growing interest in the neural underpinnings of bodily self-consciousness has shifted the focus toward dysfunctional central nervous system circuits. The present article outlays both mind-based and brain-based views highlighting their shortcomings. We propose that full insight into what should be conceived a "xenomelia spectrum disorder" will require interpretation of individual symptomatology in a social context. A proper social neuroscience of xenomelia respects the functional neuroanatomy of corporeal awareness, but also acknowledges the brain's plasticity in response to an individual's history, which is lived against a cultural background. This integrated view of xenomelia will promote the subfield of consciousness research concerned with the unity of body and self.

Recent studies have demonstrated resting-state abnormalities in midline regions in vegetative state/unresponsive wakefulness syndrome and minimally conscious state patients. However, the functional implications of these resting-state abnormalities remain unclear. Recent findings in healthy subjects have revealed a close overlap between the neural substrate of self-referential processing and the resting-state activity in cortical midline regions. As such, we investigated task-related neural activity during active self-referential processing and various measures of resting-state activity in 11 patients with disorders of consciousness (DOC) and 12 healthy control subjects. Overall, the results revealed that DOC patients exhibited task-specific signal changes in anterior and posterior midline regions, including the perigenual anterior cingulate cortex (PACC) and posterior cingulate cortex (PCC). However, the degree of signal change was significantly lower in DOC patients compared with that in healthy subjects. Moreover, reduced signal differentiation in the PACC predicted the degree of consciousness in DOC patients. Importantly, the same midline regions (PACC and PCC) in DOC patients also exhibited severe abnormalities in the measures of resting-state activity, that is functional connectivity and the amplitude of low-frequency fluctuations. Taken together, our results provide the first evidence of neural abnormalities in both the self-referential processing and the resting state in midline regions in DOC patients. This novel finding has important implications for clinical utility and general understanding of the relationship between the self, the resting state, and consciousness.

Between pathologically impaired consciousness and normal consciousness exists a scarcely researched transition zone, referred to as emergence from minimally conscious state, in which patients regain the capacity for functional communication, object use, or both. We investigated neural correlates of consciousness in these patients compared with patients with disorders of consciousness and healthy controls, by multimodal imaging. In this cross-sectional, multimodal imaging study, patients with unresponsive wakefulness syndrome, patients in a minimally conscious state, and patients who had emerged from a minimally conscious state, diagnosed with the Coma Recovery Scale-Revised, were recruited from the neurology department of the Centre Hospitalier Universitaire de Liège, Belgium. Key exclusion criteria were neuroimaging examination in an acute state, sedation or anaesthesia during scanning, large focal brain damage, motion parameters of more than 3 mm in translation and 3° in rotation, and suboptimal segmentation and normalisation. We acquired resting state functional and structural MRI data and (18)F-fluorodeoxyglucose (FDG) PET data; we used seed-based functional MRI (fMRI) analysis to investigate positive default mode network connectivity (within-network correlations) and negative default mode network connectivity (between-network anticorrelations). We correlated FDG-PET brain metabolism with fMRI connectivity. We used voxel-based morphometry to test the effect of anatomical deformations on functional connectivity. We recruited a convenience sample of 58 patients (21 [36%] with unresponsive wakefulness syndrome, 24 [41%] in a minimally conscious state, and 13 [22%] who had emerged from a minimally conscious state) and 35 healthy controls between Oct 1, 2009, and Oct 31, 2014. We detected consciousness-level-dependent increases (from unresponsive wakefulness syndrome, minimally conscious state, emergence from minimally conscious state, to healthy controls) for

"Seeing" and "feeling" architecture: how bodily self-consciousness alters architectonic experience and affects the perception of interiors.

Over the centuries architectural theory evolved several notions of embodiment, proposing in the nineteenth and twentieth century that architectonic experience is related to physiological responses of the observer. Recent advances in the cognitive neuroscience of embodiment (or bodily self-consciousness) enable empirical studies of architectonic embodiment. Here, we investigated how architecture modulates bodily self-consciousness by adapting a video-based virtual reality (VR) setup previously used to investigate visuo-tactile mechanisms of bodily self-consciousness. While standing in two different interiors, participants were filmed from behind and watched their own virtual body online on a head-mounted display (HMD). Visuo-tactile strokes were applied in synchronous or asynchronous mode to the participants and their virtual body. Two interiors were simulated in the laboratory by placing the sidewalls either far or near from the participants, generating a large and narrow room. We tested if bodily self-consciousness was differently modulated when participants were exposed to both rooms and whether these changes depend on visuo-tactile stimulation. We measured illusory touch, self-identification, and performed length estimations. Our data show that synchronous stroking of the physical and the virtual body induces illusory touch and self-identification with the virtual body, independent of room-size. Moreover, in the narrow room we observed weak feelings of illusory touch with the sidewalls and of approaching walls. These subjective changes were complemented by a stroking-dependent modulation of length estimation only in the narrow room with participants judging the room-size more accurately during conditions of illusory self-identification. We discuss our findings and previous notions of architectonic embodiment in the context of the cognitive neuroscience of bodily self-consciousness and propose an empirical framework grounded in architecture, cognitive

In experimental stroke research, anesthesia is common and serves as a major reason for translational failure. Real-time cerebral blood flow (CBF) monitoring during stroke onset can provide important information for the prediction of brain injury; however, this is difficult to achieve in clinical practice due to various technical problems. We created a photothrombotic focal ischemic stroke model utilizing our self-developed miniature headstage in conscious and freely moving rats. In this model, a high spatiotemporal resolution imager using laser speckle contrast imaging technology was integrated to acquire real-time two-dimensional CBF information during thrombosis. The feasibility, stability, and reliability of the system were tested in terms of CBF, behavior, and T2-weighted magnetic resonance imaging (MRI) findings. After completion of occlusion, the CBF in the targeted cortex of the stroke group was reduced to 16±9% of the baseline value. The mean infarct volume measured by MRI 24 h postmodeling was 77±11 mm3 and correlated well with CBF (R2=0.74). This rodent model of focal cerebral ischemia and real-time blood flow imaging opens the possibility of performing various fundamental and translational studies on stroke without the influence of anesthetics.

Borderline Personality Disorder and Self-Conscious Affect: Too Much Shame But Not Enough Guilt?

Peters, Jessica R.; Geiger, Paul J.

2016-01-01

Shame has emerged as a particularly relevant emotion to the maintenance and exacerbation of borderline personality disorder (BPD) features; however, little attention has been paid to the potentially differing effects of other forms of self-conscious affect. While guilt has been demonstrated to have adaptive functions in the social psychology literature, it has not been previously explored whether a lack of socially adaptive guilt might also contribute to BPD-related dysfunction. The present study examined the relationship between BPD features and self-conscious emotions in a sample of undergraduate students (n=839). Increased shame and decreased guilt independently accounted for significant variance in the association between BPD features and anger, hostility, and externalization of blame. Only increased shame significantly mediated the association between BPD features and anger rumination, and only decreased guilt significantly mediated the relationship between BPD features and aggression. These findings suggest BPD and its associated problems with anger and externalizing may be characterized not only by high levels of shame, but also by lower levels of guilt. Clinical implications include the need to differentiate between self-conscious emotions and teach adaptive responses to warranted guilt. PMID:26866901

Who Am I, and Who Do I Strive to Be? Applying a Theory of Self-Conscious Emotions to Medical Education.

PubMed

Bynum, William E; Artino, Anthony R

2018-06-01

The self-conscious emotions of shame, guilt, and pride are a distinct set of cognitively complex, powerful, and ubiquitous emotions that arise when an individual engages in self-evaluation. Currently, little is known about the influence or outcomes of self-conscious emotions in medical learners. In this article, the authors present a leading theory of self-conscious emotions that outlines the appraisals and attributions that give rise to and differentiate shame, guilt, and two forms of pride. The authors then apply the theory to three relevant topics in medical education: perfectionism, professional identity formation, and motivation. In doing so, the authors present novel ways of viewing these topics through the lens of self-conscious emotion, suggest areas of future research, and outline a framework for emotional resilience training. Ultimately, the goal of this article is to highlight the fundamental nature of shame, guilt, and pride, which the authors believe are underappreciated and understudied in medical education, and to inform future empirical study on the role that these emotions might play in medical education. Additionally, from a practical standpoint, this article aims to encourage educators and learners to recognize self-conscious emotions in themselves and their colleagues, and to begin developing more resilient approaches to learning-approaches that acknowledge and confront shame, guilt, and pride in medical education.

Label-Free Imaging of Female Genital Tract Melanocytic Lesions With Pump-Probe Microscopy: A Promising Diagnostic Tool.

Melanomas of the female genital tract present a unique clinical challenge. Not only are these lesions in an anatomically sensitive area, but also they tend to be multifocal and have high recurrence rates. Furthermore, several benign melanocytic proliferations resemble early-stage melanoma clinically and/or histopathologically. Thus, there is a significant need for additional tools that can help correctly diagnose and stage these lesions. Here, we quantitatively and nondestructively analyze the chemical composition of melanin in excised pigmented lesions of the female genital tract using pump-probe microscopy, a high-resolution optical imaging technique that is sensitive to many biochemical properties of melanin. Thirty-one thin (~5 μm) tissue sections previously excised from female genital tract melanocytic lesions were imaged with pump-probe microscopy and analyzed. We find significant quantitative differences in melanin type and structure between melanoma and nonmalignant melanocytic proliferations. Our analysis also suggests a link between the molecular signatures of melanins and lesion-specific genetic mutations. Finally, significant differences are found between metastatic and nonmetastatic melanomas. The limitations of this work include the fact that molecular information is restricted to melanin pigment and the sample size is relatively small. Pump-probe microscopy provides unique information regarding the biochemical composition of genital tract melanocytic lesions, which can be used to improve the diagnosis and staging of vulvar melanomas.

[The mind-brain problem (II): about consciousness].

Consciousness is the result of a series of neurobiological processes in the brain and is, in turn, a feature of the level of its complexity. In fact, being conscious and being aware place us before what Chalmers called the 'soft problem' and the 'hard problem' of consciousness. The first refers to aspects such as wakefulness, attention or knowledge, while the second is concerned with such complex concepts as self-awareness, 'neural self' or social cognition. In this sense it can be said that the concept of consciousness as a unitary thing poses problems of approaching a highly complex reality. We outline the main models that have addressed the topic of consciousness from a neuroscientific perspective. On the one hand, there are the conscious experience models of Crick, Edelman and Tononi, and Llinas, and, on the other, the models and neuronal bases of self-consciousness by authors such as Damasio (core and extended consciousness), Tulving (autonoetic and noetic consciousness and chronesthesia), the problem of qualia (Dennett, Popper, Ramachandran) and the cognit model (Fuster). All the stimuli we receive from the outside world and from our own internal world are converted and processed by the brain so as to integrate them, and from there they become part of our identity. The perception of a dog and being able to recognise it as such or the understanding of our own consciousness are the result of the functioning of brain, neuronal and synaptic structures. The more complex processes of consciousness, such as self-awareness or empathy, are probably emergent brain processes.

In this study, we examine race/ethnic consciousness and its associations with experiences of racial discrimination and health in New Zealand. Racism is an important determinant of health and cause of ethnic inequities. However, conceptualising the mechanisms by which racism impacts on health requires racism to be contextualised within the broader social environment. Race/ethnic consciousness (how often people think about their race or ethnicity) is understood as part of a broader assessment of the ‘racial climate’. Higher race/ethnic consciousness has been demonstrated among non-dominant racial/ethnic groups and linked to adverse health outcomes in a limited number of studies. We analysed data from the 2006/07 New Zealand Health Survey, a national population-based survey of New Zealand adults, to examine the distribution of ethnic consciousness by ethnicity, and its association with individual experiences of racial discrimination and self-rated health. Findings showed that European respondents were least likely to report thinking about their ethnicity, with people from non-European ethnic groupings all reporting relatively higher ethnic consciousness. Higher ethnic consciousness was associated with an increased likelihood of reporting experience of racial discrimination for all ethnic groupings and was also associated with fair/poor self-rated health after adjusting for age, sex and ethnicity. However, this difference in health was no longer evident after further adjustment for socioeconomic position and individual experience of racial discrimination. Our study suggests different experiences of racialised social environments by ethnicity in New Zealand and that, at an individual level, ethnic consciousness is related to experiences of racial discrimination. However, the relationship with health is less clear and needs further investigation with research to better understand the racialised social relations that create and maintain ethnic inequities in health in

In Vivo and Ex Vivo Imaging Reveals a Long-Lasting Chlamydial Infection in the Mouse Gastrointestinal Tract following Genital Tract Inoculation

2015-01-01

Intravaginal infection with Chlamydia muridarum in mice can ascend to the upper genital tract, resulting in hydrosalpinx, a pathological hallmark for tubal infertility in women infected with C. trachomatis. Here, we utilized in vivo imaging of C. muridarum infection in mice following an intravaginal inoculation and confirmed the rapid ascent of the chlamydial organisms from the lower to upper genital tracts. Unexpectedly, the C. muridarum-derived signal was still detectable in the abdominal area 100 days after inoculation. Ex vivo imaging of the mouse organs revealed that the long-lasting presence of the chlamydial signal was restricted to the gastrointestinal (GI) tract, which was validated by directly measuring the chlamydial live organisms and genomes in the same organs. The C. muridarum organisms spreading from the genital to the GI tracts were detected in different mouse strains and appeared to be independent of oral or rectal routes. Mice prevented from orally taking up excretions also developed the long-lasting GI tract infection. Inoculation of C. muridarum directly into the upper genital tract, which resulted in a delayed vaginal shedding of live organisms, accelerated the chlamydial spreading to the GI tract. Thus, we have demonstrated that the genital tract chlamydial organisms may use a systemic route to spread to and establish a long-lasting infection in the GI tract. The significance of the chlamydial spreading from the genital to GI tracts is discussed. PMID:26099591

From multisensory integration in peripersonal space to bodily self-consciousness: from statistical regularities to statistical inference.

PubMed

Noel, Jean-Paul; Blanke, Olaf; Serino, Andrea

2018-06-06

Integrating information across sensory systems is a critical step toward building a cohesive representation of the environment and one's body, and as illustrated by numerous illusions, scaffolds subjective experience of the world and self. In the last years, classic principles of multisensory integration elucidated in the subcortex have been translated into the language of statistical inference understood by the neocortical mantle. Most importantly, a mechanistic systems-level description of multisensory computations via probabilistic population coding and divisive normalization is actively being put forward. In parallel, by describing and understanding bodily illusions, researchers have suggested multisensory integration of bodily inputs within the peripersonal space as a key mechanism in bodily self-consciousness. Importantly, certain aspects of bodily self-consciousness, although still very much a minority, have been recently casted under the light of modern computational understandings of multisensory integration. In doing so, we argue, the field of bodily self-consciousness may borrow mechanistic descriptions regarding the neural implementation of inference computations outlined by the multisensory field. This computational approach, leveraged on the understanding of multisensory processes generally, promises to advance scientific comprehension regarding one of the most mysterious questions puzzling humankind, that is, how our brain creates the experience of a self in interaction with the environment. © 2018 The Authors.

Pathomorphological findings for the male genital are an exception among forensic cases. In earlier publications they were usually published as individual cases. A significant percentage are the so-called fertility- and potency medical certificates, which are usually commissioned for doubtful paternity cases. Old forensic writings about genital injuries distinguish--apart from the necessity of a complete dissection--between "deadly as such" and "accidentally deadly" injuries. Another group consists of reports about self-inflicted genital mutilation, e.g. among prison inmates or soldiers of the last world wars to become an invalid. When it was necessary to identify a corpse, e.g. in cases of progressive decomposition, Merkel recommended in 1945 the representation of the so-called "Schnepfenkopf" (snipe head; colliculus seminalis) in the lesser pelvis. In this article a medical and forensic review of forensically relevant findings of the male genital is presented and illustrated with historical cases.

The mechanism of consciousness and loss of conciousness by general anesthetics are crucial issue for the anesthesiologists. Recent non-invasive brain-imaging technology brings about light to various our emotions and sensations in human brain; however, neural correlate of consciousness is not yet still elucidated. The concept "the seat of the consciousness (is in the subcortical nuclei)" is now completely denied, but instead the consciousness is based on the idea that connectivity and communications across cortical and thalamocortical networks. Anesthetics and sleep disrupt the networks that encompass complexity and integration. The compatibility between complexity and integration is the key feature of the consciousness, which is represented by complex, extensive, communicative and integrative electroencephalograph currents evoked by transcranial magnetic stimulation, provoking a single unified conscious experience in us, humans.

Laser Doppler imaging of genital blood flow: a direct measure of female sexual arousal.

PubMed

Waxman, Samantha E; Pukall, Caroline F

2009-08-01

Female sexual arousal is a challenging construct to measure, partly because of the subtle nature of its indicators, vaginal lubrication and genital swelling. As a result, many instruments have been used in an attempt to accurately measure it; however, problems are associated with each. Furthermore, the relationship between subjective and physiological indicators of arousal appears to be influenced by the instrument used to measure physiological arousal. Specifically, instruments measuring physiological arousal internally yield lower correlations between measures of physiological and subjective arousal than instruments examining the external genitals. Laser Doppler imaging (LDI) is a direct measure of external genital blood flow. The purpose of this study was to investigate the usefulness of LDI for measuring genital blood flow in women in response to erotic visual stimuli, and to explore the relationship between physiological and subjective sexual arousal. Sixty-five participants watched three 15-minute films during LDI scanning. Two nature films (measuring acclimatization and baseline blood flow levels) and one randomly assigned experimental film (erotic, anxiety, humor, or neutral) were used. Participants rated their level of subjective arousal following the third film. Results indicated a significant effect of film condition on genital blood flow, P < 0.001, with the erotic condition differing significantly from the other three conditions. In terms of the relationship between physiological and subjective sexual arousal, physiological arousal was significantly predicted by subjective ratings of sexual arousal (P < 0.001). LDI appears to be able to differentiate blood flow during erotic and nonerotic conditions. In addition, physiological sexual arousal was significantly predicted by women's reported subjective sexual arousal. These findings suggest that LDI is a useful instrument for measuring female sexual arousal, and that women may be more aware of their level

Consciousness: a unique way of processing information.

PubMed

Marchetti, Giorgio

2018-02-08

In this article, I argue that consciousness is a unique way of processing information, in that: it produces information, rather than purely transmitting it; the information it produces is meaningful for us; the meaning it has is always individuated. This uniqueness allows us to process information on the basis of our personal needs and ever-changing interactions with the environment, and consequently to act autonomously. Three main basic cognitive processes contribute to realize this unique way of information processing: the self, attention and working memory. The self, which is primarily expressed via the central and peripheral nervous systems, maps our body, the environment, and our relations with the environment. It is the primary means by which the complexity inherent to our composite structure is reduced into the "single voice" of a unique individual. It provides a reference system that (albeit evolving) is sufficiently stable to define the variations that will be used as the raw material for the construction of conscious information. Attention allows for the selection of those variations in the state of the self that are most relevant in the given situation. Attention originates and is deployed from a single locus inside our body, which represents the center of the self, around which all our conscious experiences are organized. Whatever is focused by attention appears in our consciousness as possessing a spatial quality defined by this center and the direction toward which attention is focused. In addition, attention determines two other features of conscious experience: periodicity and phenomenal quality. Self and attention are necessary but not sufficient for conscious information to be produced. Complex forms of conscious experiences, such as the various modes of givenness of conscious experience and the stream of consciousness, need a working memory mechanism to assemble the basic pieces of information selected by attention.

Effects of Genital Response Measurement Device and Stimulus Characteristics on Sexual Concordance in Women.

PubMed

Bouchard, Katrina N; Chivers, Meredith L; Pukall, Caroline F

2017-01-01

Investigations of sexual concordance suggest that, on average, women exhibit a low, positive correlation between their subjective sexual arousal and genital response. However, this relationship appears to be stronger, on average, when genital response is measured via the external tissues of the vulva than within the vagina walls. Given the methodological variations, such as stimulus content and duration, in studies of vulvar and vaginal concordance, direct comparisons between individual studies are limited. In the current study, sexual concordance was examined using concurrent measures of vulvar blood flow (using laser Doppler imaging) and vaginal vasocongestion (using vaginal photoplethysmography) to investigate potential differences in vulvar and vaginal concordance. Twenty-five women viewed two erotic films that differed in sexual activity content (foreplay and intercourse) while their subjective sexual arousal and genital response was measured. In support of previous meta-analytic findings, results suggest that subjective sexual arousal is more strongly correlated with vulvar blood flow than with vaginal vasocongestion. Likewise, perceived genital response and actual vulvar blood flow are more strongly related than are vaginal vasocongestion and self-reported genital sensations. Practical implications for the study of women's sexual concordance as well as broader implications for the understanding of female sexuality are considered.

To (1) examine the prevalence of abnormal genital findings in a large cohort of female children presenting with concerns of sexual abuse; and (2) explore how children use language when describing genital contact and genital anatomy. In this prospective study we documented medical histories and genital findings in all children who met inclusion criteria. Findings were categorized as normal, indeterminate, and diagnostic of trauma. Logistic regression analysis was used to determine the effects of key covariates on predicting diagnostic findings. Children older than 4 years of age were asked questions related to genital anatomy to assess their use of language. A regional, university-affiliated sexual abuse clinic. Female children (N = 1500) aged from birth to 17 years (inclusive) who received an anogenital examination with digital images. Physical exam findings, medical history, and the child's use of language were recorded. Physical findings were determined in 99% (n = 1491) of patients. Diagnostic findings were present in 7% (99 of 1491). After adjusting for age, acuity, and type of sexual contact reported by the adult, the estimated odds of diagnostic findings were 12.5 times higher for children reporting genital penetration compared with those who reported only contact (95% confidence interval, 3.46-45.34). Finally, children used the word "inside" to describe contact other than penetration of the vaginal canal (ie, labial penetration). A history of penetration by the child was the primary predictor of diagnostic findings. Interpretation of children's use of "inside" might explain the low prevalence of diagnostic findings and warrants further study.

The few studies that have examined the neural correlates of genital arousal have focused on men and are methodologically hard to compare. To investigate the neural correlates of peripheral physiologic sexual arousal using identical methodology for men and women. 2 groups (20 men, 20 women) viewed movie clips (erotic, humor) while genital temperature was continuously measured using infrared thermal imaging. Participants also continuously evaluated changes in their subjective arousal and answered discrete questions about liking the movies and wanting sexual stimulation. Brain activity, indicated by blood oxygen level-dependent (BOLD) response, was measured using functional magnetic resonance imaging. BOLD responses, genital temperature, and subjective sexual arousal. BOLD activity in a number of brain regions was correlated with changes in genital temperature in men and women; however, activation in women appeared to be more extensive than in men, including the anterior and posterior cingulate cortex, right cerebellum, insula, frontal operculum, and paracingulate gyrus. Examination of the strength of the correlation between BOLD response and genital temperature showed that women had a stronger brain-genital relation compared with men in a number of regions. There were no brain regions in men with stronger brain-genital correlations than in women. Our findings shed light on the neurophysiologic processes involved in genital arousal for men and women. Further research examining the specific brain regions that mediate our findings is necessary to pave the way for clinical application. A strength of the study is the use of thermography, which allows for a direct comparison of the neural correlates of genital arousal in men and women. This study has the common limitations of most laboratory-based sexual arousal research, including sampling bias, lack of ecologic validity, and equipment limitations, and those common to neuroimaging research, including BOLD signal

Acromegaly is associated with impaired quality of life (QoL) and causes anatomical disproportions, which may contribute to the decreased QoL after successful treatment. The Derriford appearance scale 59 (DAS59) is a questionnaire measuring psychological distress and disruptions to everyday life associated with self-consciousness of appearance. Investigate the psychological distress and dysfunction related to self-consciousness about appearance and its effect on QoL in patients in long-term remission of acromegaly. Patients (>18 years old) treated for acromegaly at the Department of Endocrinology of the Radboud University Medical Center Nijmegen were invited to participate. A gender-, age- and body mass index matched control group was provided by the patients themselves. Participants were asked to complete the modified DAS59-, research and development 36- (RAND-36), acromegaly quality of life questionnaire (AcroQoL) and a sociodemographic questionnaire. Differences between patient- and control groups and correlations between questionnaire scores and clinical characteristics collected from medical records were analyzed. Questionnaire scores. Of the 120 respondents, 73 agreed to participate [all cured or under biochemical control, median remission time 10.5 years (range 2.3-43.6 years)]. Of these, 34 (46.6%) reported self-consciousness about their appearance. Twenty-nine of these patients (85.3%) pointed out their face to be a prominent source of self-consciousness. Fifty-seven matched control subjects were included as well. Significant correlations were found between the scores of the DAS59 and the AcroQoL, RAND-36 and VAS in patients. Even after long-term remission of acromegaly, a large number of patients are self-conscious about their appearance, leading to psychological distress and disruptions to everyday life and decreased QoL. Facial features were the most important source of self-consciousness. This stresses the importance of addressing self-consciousness of

Consciousness, the brain, and spacetime geometry.

PubMed

Hameroff, S

2001-04-01

What is consciousness? Conventional approaches see it as an emergent property of complex interactions among individual neurons; however these approaches fail to address enigmatic features of consciousness. Accordingly, some philosophers have contended that "qualia," or an experiential medium from which consciousness is derived, exists as a fundamental component of reality. Whitehead, for example, described the universe as being composed of "occasions of experience." To examine this possibility scientifically, the very nature of physical reality must be re-examined. We must come to terms with the physics of spacetime--as described by Einstein's general theory of relativity, and its relation to the fundamental theory of matter--as described by quantum theory. Roger Penrose has proposed a new physics of objective reduction: "OR," which appeals to a form of quantum gravity to provide a useful description of fundamental processes at the quantum/classical borderline. Within the OR scheme, we consider that consciousness occurs if an appropriately organized system is able to develop and maintain quantum coherent superposition until a specific "objective" criterion (a threshold related to quantum gravity) is reached; the coherent system then self-reduces (objective reduction: OR). We contend that this type of objective self-collapse introduces non-computability, an essential feature of consciousness which distinguishes our minds from classical computers. Each OR is taken as an instantaneous event--the climax of a self-organizing process in fundamental spacetime--and a candidate for a conscious Whitehead "occasion of experience." How could an OR process occur in the brain, be coupled to neural activities, and account for other features of consciousness? We nominate a quantum computational OR process with the requisite characteristics to be occurring in cytoskeletal micro-tubules within the brain's neurons. In this model, quantum-superposed states develop in microtubule

The development of bodily self-consciousness: changing responses to the Full Body Illusion in childhood.

2018-05-01

The present work investigates the development of bodily self-consciousness and its relation to multisensory bodily information, by measuring for the first time the development of responses to the full body illusion in childhood. We tested three age groups of children: 6- to 7-year-olds (n = 28); 8- to 9-year-olds (n = 21); 10- to 11-year-olds (n = 19), and a group of adults (n = 31). Each participant wore a head-mounted display (HMD) which displayed a view from a video camera positioned 2 metres behind their own back. Thus, they could view a virtual body from behind. We manipulated visuo-tactile synchrony by showing the participants a view of their virtual back being stroked with a stick at the same time and same place as their real back (synchronous condition), or at different times and places (asynchronous condition). After each period of stroking, we measured three aspects of bodily self-consciousness: drift in perceived self-location, self-identification with the virtual body, and touch referral to the virtual body. Results show that self-identification with the virtual body was significantly stronger in the synchronous condition than in the asynchronous condition even in the youngest group tested; however, the size of this effect increased with age. Touch referral to the virtual body was greater in the synchronous condition than in the asynchronous condition only for 10- to 11-year-olds and adults. Drift in perceived self-location was greater in the synchronous condition than in the asynchronous condition only for adults. Thus, the youngest age tested can self-identify with a virtual body, but the links between multisensory signals and bodily self-consciousness develop significantly across childhood. This suggests a long period of development of the bodily self and exciting potential for the use of virtual reality technologies with children. © 2017 John Wiley & Sons Ltd.

A Case of Genital Self-Mutilation in a Female-Symptom Choice and Meaning.

PubMed

Conde, Ema; Santos, Telma; Leite, Rita; Vicente, Carla; Figueiredo, António Mesquita

2017-08-18

Self-mutilation is understood as any willful gesture or alteration of the body tissue without a suicidal intent. The most common self-mutilating gestures are, to a great extent, those that are superficial or moderate, such as cuts, burns, or bites. The most severe, as is the case of genital self-mutilation (GSM), are extremely rare and, in most cases, observed in patients suffering from psychosis. Furthermore, they are mostly reported from a surgical standpoint. Here, we report the case of a 20-year-old female patient who resorted to the emergency department after having amputated her clitoris with surgical scissors. This dramatic gesture, coupled with the patient's narrative, prompted for differential diagnosis between a psychotic syndrome and a severe personality disorder. We propose that, despite the magnitude of the self-harm, it is possible to conceptualize this GSM within a disturbed personality with significant sexuality issues and, therefore, this case report aims to broaden the limits that have been associated with the self-mutilating gestures in borderline personality disorder.

Exercise identity and attribution properties predict negative self-conscious emotions for exercise relapse.

Flora, Parminder K; Strachan, Shaelyn M; Brawley, Lawrence R; Spink, Kevin S

2012-10-01

Research on exercise identity (EXID) indicates that it is related to negative affect when exercisers are inconsistent or relapse. Although identity theory suggests that causal attributions about this inconsistency elicit negative self-conscious emotions of shame and guilt, no EXID studies have examined this for exercise relapse. Weiner's attribution-based theory of interpersonal motivation (2010) offers a means of testing the attribution-emotion link. Using both frameworks, we examined whether EXID and attributional properties predicted negative emotions for exercise relapse. Participants (n = 224) read an exercise relapse vignette, and then completed EXID, attributions, and emotion measures. Hierarchical multiple regression models using EXID and the attributional property of controllability significantly predicted each of shame and guilt, R² adjusted = .09, ps ≤ .001. Results support identity theory suggestions and Weiner's specific attribution-emotion hypothesis. This first demonstration of an interlinking of EXID, controllability, and negative self-conscious emotions offers more predictive utility using complementary theories than either theory alone.

The rise of machine consciousness: studying consciousness with computational models.

Reggia, James A

2013-08-01

Efforts to create computational models of consciousness have accelerated over the last two decades, creating a field that has become known as artificial consciousness. There have been two main motivations for this controversial work: to develop a better scientific understanding of the nature of human/animal consciousness and to produce machines that genuinely exhibit conscious awareness. This review begins by briefly explaining some of the concepts and terminology used by investigators working on machine consciousness, and summarizes key neurobiological correlates of human consciousness that are particularly relevant to past computational studies. Models of consciousness developed over the last twenty years are then surveyed. These models are largely found to fall into five categories based on the fundamental issue that their developers have selected as being most central to consciousness: a global workspace, information integration, an internal self-model, higher-level representations, or attention mechanisms. For each of these five categories, an overview of past work is given, a representative example is presented in some detail to illustrate the approach, and comments are provided on the contributions and limitations of the methodology. Three conclusions are offered about the state of the field based on this review: (1) computational modeling has become an effective and accepted methodology for the scientific study of consciousness, (2) existing computational models have successfully captured a number of neurobiological, cognitive, and behavioral correlates of conscious information processing as machine simulations, and (3) no existing approach to artificial consciousness has presented a compelling demonstration of phenomenal machine consciousness, or even clear evidence that artificial phenomenal consciousness will eventually be possible. The paper concludes by discussing the importance of continuing work in this area, considering the ethical issues it raises

Genital herpes stigma: Toward the Measurement and Validation of a highly prevalent yet hidden public health problem.

Despite its highly prevalent and stigmatizing nature, genital herpes has received little attention from stigma researchers relative to other sexually transmitted infections. This limitation is of great relevance to researchers and practitioners in both clinical and healthcare settings, given that stigma can cause psychological distress and hinder disclosure to sexual partners, hence contributing to the spread of genital herpes. The present research developed and examined the psychometric properties of a quantitative measure of genital herpes stigma. Two hundred individuals diagnosed with genital herpes recruited through online genital herpes support groups completed a survey containing 37 items adapted from the HIV Stigma Scale, questions about demographic and herpes-related characteristics, and measures of relevant psychosocial variables. A confirmatory factor analysis yielded an 18-item scale with four factors: personalized stigma, disclosure concerns, negative self-image, and concern with public attitudes. All subscales demonstrated good internal consistency, with Cronbach alphas ranging from 0.74 to 0.87. Construct validity was supported by correlations with relevant psychosocial variables, including negative affect, rumination, and perceived social support. As a psychometrically sound assessment tool, the Genital Herpes Stigma Scale can be used in both clinical and research settings to facilitate future efforts to alleviate the negative psychological consequences of this incurable viral infection.

Consciousness in dreams.

PubMed

Kahn, David; Gover, Tzivia

2010-01-01

This chapter argues that dreaming is an important state of consciousness and that it has many features that complement consciousness in the wake state. The chapter discusses consciousness in dreams and how it comes about. It discusses the changes that occur in the neuromodulatory environment and in the neuronal connectivity of the brain as we fall asleep and begin our night journeys. Dreams evolve from internal sources though the dream may look different than any one of these since something entirely new may emerge through self-organizing processes. The chapter also explores characteristics of dreaming consciousness such as acceptance of implausibility and how that might lead to creative insight. Examples of studies, which have shown creativity in dream sleep, are provided to illustrate important characteristics of dreaming consciousness. The chapter also discusses the dream body and how it relates to our consciousness while dreaming. Differences and similarities between wake, lucid, non-lucid and day dreaming are explored and the chapter concludes with a discussion on what we can learn from each of these expressions of consciousness.

Preferential processing of self-relevant stimuli occurs mainly at the perceptual and conscious stages of information processing.

PubMed

Tacikowski, P; Ehrsson, H H

2016-04-01

Self-related stimuli, such as one's own name or face, are processed faster and more accurately than other types of stimuli. However, what remains unknown is at which stage of the information processing hierarchy this preferential processing occurs. Our first aim was to determine whether preferential self-processing involves mainly perceptual stages or also post-perceptual stages. We found that self-related priming was stronger than other-related priming only because of perceptual prime-target congruency. Our second aim was to dissociate the role of conscious and unconscious factors in preferential self-processing. To this end, we compared the "self" and "other" conditions in trials where primes were masked or unmasked. In two separate experiments, we found that self-related priming was stronger than other-related priming but only in the unmasked trials. Together, our results suggest that preferential access to the self-concept occurs mainly at the perceptual and conscious stages of the stimulus processing hierarchy. Copyright © 2016 The Authors.

Conscious Leadership.

PubMed

Ward, Suzanne F; Haase, Beth

2016-11-01

Health care leaders need to use leadership methodologies that support safe patient care, satisfy employees, and improve the bottom line. Conscious leaders help create desirable personal and professional life experiences for themselves using specific tools that include mindfulness, context, and the observer-self, and they strive to help their employees learn to use these tools as well. In perioperative nursing, conscious leaders create an environment in which nurses are supported in their aim to provide the highest level of patient care and in which transformations are encouraged to take place; this environment ultimately promotes safety, contributes to fulfilling and meaningful work, and enhances a facility's financial viability. This article discusses some of the key concepts behind conscious leadership, how perioperative leaders can reach and maintain expanded consciousness, and how they can best assist their staff members in their own evolution to a more mindful state.

Person and consciousness.

PubMed

Crosby, J F

2000-04-01

My interlocuter is Locke with his reduction of person to personal consciousness. This reduction is a main reason preventing people from acknowledging the personhood of the earliest human embryo, which lacks all personal consciousness. I show that Catholic Christians who live the sacramental life of the Church have reason to think that they are, as persons, vastly more than what they experience themselves to be, for they believe that the sacraments work effects in them as persons that can only be believed but that cannot be experienced within themselves in this life. I also show that Christians and non-Christians alike have an experience of moral good and evil in themselves that implies that they are, as moral persons, far more than they find in their conscious self-presence. It is, therefore, natural to think that if my being a person so far exceeds my consciousness, I may well have once existed as person even before the awakening of consciousness.

This investigation aims to evaluate the validity of self-assessment of pubertal Tanner stage in representative Chinese children and adolescents. The study is a nationally representative cross-sectional survey in eight research sites in the large project entitled 'China Puberty Research Collaboration'. Weight, height, self-assessed pubertal Tanner stage and physical examination of pubic hair in each gender, breast development in girls and genital development in boys from were analysed. Realistic colour images of pubertal rating were used as self-assessment of pubertal stage. A large proportion of subjects aged 7.9-18.9 years old were capable of identifying their own pubertal Tanner stage accurately or close to the rater's assessments. Obese group tends to overestimate their pubertal development compared to non-obese peers, except for genital assessment in boys. The k values for non-obese and obese girls were 0.619 (p < 0.0001) and 0.527 (p < 0.0001), respectively, while the k values for non-obese and obese boys were 0.503 (p < 0.0001) and 0.352 (p < 0.0001). Self-assessment of the pubertal stage by using realistic colour images could be a better alternative assessment tool for large epidemiological puberty research compared with Tanner's original black and white pictures. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

We analysed 528 genital self-collected swabs (SCS) from 67 HIV-1 and herpes simplex virus type-2 (HSV-2) co-infected women collected during the placebo month of a randomized crossover clinical trial of suppressive acyclovir in Chiang Rai, Thailand. In this first longitudinal study of HIV-1 and HSV-2 co-infected women using genital SCS specimens, we found frequent mucosal HIV-1 shedding. Overall, 372 (70%) swabs had detectable HIV-1 RNA with median HIV-1 viral load of 2.61 log(10) copies/swab. We found no statistically significant association between detectable HIV-1 RNA and HSV-2 DNA in the same SCS specimen (adjusted odds ratio [aOR] 1.40; 95% confidence intervals [CI], 0.78-2.60, P = 0.25). Only baseline HIV-1 plasma viral load was independently associated with genital HIV-1 RNA shedding (aOR, 7.6; 95% CI, 3.3-17.2, P < 0.0001). SCS may be useful for future HIV-1 and HSV-2 studies because this method allows for frequent genital sampling, and inclusion of genital sites other than the cervix.

Consciousness, brain, neuroplasticity

PubMed Central

Askenasy, Jean; Lehmann, Joseph

2013-01-01

Subjectivity, intentionality, self-awareness and will are major components of consciousness in human beings. Changes in consciousness and its content following different brain processes and malfunction have long been studied. Cognitive sciences assume that brain activities have an infrastructure, but there is also evidence that consciousness itself may change this infrastructure. The two-way influence between brain and consciousness has been at the center of philosophy and less so, of science. This so-called bottom-up and top-down interrelationship is controversial and is the subject of our article. We would like to ask: how does it happen that consciousness may provoke structural changes in the brain? The living brain means continuous changes at the synaptic level with every new experience, with every new process of learning, memorizing or mastering new and existing skills. Synapses are generated and dissolved, while others are preserved, in an ever-changing process of so-called neuroplasticity. Ongoing processes of synaptic reinforcements and decay occur during wakefulness when consciousness is present, but also during sleep when it is mostly absent. We suggest that consciousness influences brain neuroplasticity both during wakefulness as well as sleep in a top-down way. This means that consciousness really activates synaptic flow and changes brain structures and functional organization. The dynamic impact of consciousness on brain never stops despite the relative stationary structure of the brain. Such a process can be a target for medical intervention, e.g., by cognitive training.

Choking under pressure occurs when an individual underperforms due to situational pressure. The present study examined whether being the target of a positive social stereotype regarding math ability causes choking among men. Gender identification and self-consciousness were hypothesized to moderate the effect of math-gender stereotypes on men's math test performance. Men high in self-consciousness but low in gender identification significantly underperformed when exposed to gender-relevant test instructions. No significant effects were found under a gender-irrelevant condition. These findings are discussed in the contexts of research on stereotype threat, stereotype lift, and choking under pressure.

2010-08-01

The purpose of this study was to test a model where body-related self-conscious emotions of shame, guilt, and pride were associated with physical activity regulations and behavior. Adult women (N = 389; M age = 29.82, SD = 15.20 years) completed a questionnaire assessing body-related pride, shame, and guilt, motivational regulations, and leisure-time physical activity. The hypothesized measurement and structural models were deemed adequate, as was a revised model examining shame-free guilt and guilt-free shame. In the revised structural model, body-related pride was positively significantly related to identified and intrinsic regulations. Body-related shame-free guilt was significantly associated with external, introjected, and identified regulations. Body-related guilt-free shame was significantly positively related to external and introjected regulation, and negatively associated with intrinsic regulation. Identified and intrinsic regulations were significantly positively related to physical activity (R2 = .62). These findings highlight the importance of targeting and understanding the realm of body-related self-conscious emotions and the associated links to regulations and physical activity behavior.

The leading cause of sexually transmitted bacterial infection is Chlamydia trachomatis. The aim of this study is to investigate the early events in colonization of this bacterium within the murine genital tract. An in vivo animal body imaging technology was used to track fluorophore labeled C. muridarum elementary bodies (EBs) inoculated intravaginally in C57BL/6 mice during the first 24 h of infection. Ascension of viable EBs was observed (1) to be localized to the lower regions of the murine genital tract within the first 24 h post challenge and (2) was dose independent during this early exposure period. Molecular detection revealed enhanced bacterial load in lower regions of the genital tract with increasing bacterial load in the upper region beginning 12 h post inoculation. This study provides additional insight into chlamydial colonization in the murine genital tract during the first 12-24 h following inoculation.

Guidelines for the Standardization of Genital Photography.

Plastic surgery relies on photography for both clinical practice and research. The Photographic Standards in Plastic Surgery laid the foundation for standardized photography in plastic surgery. Despite these advancements, the current literature lacks guidelines for genital photography, thus resulting in a discordance of documentation. The authors propose photographic standards for the male and female genitalia to establish homogeneity in which information can be accurately exchanged. All medical photographs include a sky-blue background, proper lighting, removal of distractors, consistent camera framing, and standard camera angles. We propose the following guidelines to standardize genital photography. In the anterior upright position, feet are shoulder-width apart and arms are placed posteriorly. The frame is bounded superiorly by the xiphoid-umbilicus midpoint and inferiorly by the patella. For circumferential documentation, frontal 180 degree capture via 45 degree intervals is often sufficient. Images in standard lithotomy position should be captured at both parallel and 45 degrees above the horizontal. Images of the phallus should include both the flaccid and erect states. Despite the increasing incidence of genital procedures, there lacks a standardized methodology in which to document the genitalia, resulting in a substantial heterogeneity in the current literature. Our standardized techniques for genital photography set forth to establish a uniform language that promotes more effective communication with both the patient as well as with colleagues. The proposed photography guidelines provide optimal visualization and standard documentation of the genitalia, allowing for accurate education, meaningful collaborations, and advancement in genital surgery. © 2018 The American Society for Aesthetic Plastic Surgery, Inc.

Space, self, and the theater of consciousness.

PubMed

Trehub, Arnold

2007-06-01

Over a decade ago, I introduced a large-scale theory of the cognitive brain which explained for the first time how the human brain is able to create internal models of its intimate world and invent models of a wider universe. An essential part of the theoretical model is an organization of neuronal mechanisms which I have named the Retinoid Model [Trehub, A. (1977). Neuronal models for cognitive processes: Networks for learning, perception and imagination. Journal of Theoretical Biology, 65, 141-169; Trehub, A. (1991). The Cognitive Brain: MIT Press]. This hypothesized brain system has structural and dynamic properties enabling it to register and appropriately integrate disparate foveal stimuli into a perspectival, egocentric representation of an extended 3D world scene including a neuronally tokened locus of the self which, in this theory, is the neuronal origin of retinoid space. As an integral part of the larger neuro-cognitive model, the retinoid system is able to perform many other useful perceptual and higher cognitive functions. In this paper, I draw on the hypothesized properties of this system to argue that neuronal activity within the retinoid structure constitutes the phenomenal content of consciousness and the unique sense of self that each of us experiences.

In this invited commentary I focus on the topic addressed in three papers: De Sousa's (2013[1617]) Toward an Integrative Theory of Consciousness, a monograph with Parts 1 & 2, as well as commentaries by Pereira (2013a[59]) and Hirstein (2013[42]). All three are impressively scholarly and can stand—and shout—on their own. But theory of consciousness? My aim is to slice that topic into the two fundamentally different kinds of theories of consciousness, say what appears to be an ideology, out of behaviourism into cognitivism, now also influencing the quest for an “explanation of consciousness” in cognitive neuroscience. I will then say what can be expected given what we know of the complexity of brain structure, the richness of a conscious “vocabulary”, and current technological limits of brain imaging. This will then turn to the strategy for examining “what consciousness explains”—metatheory, theories, mappings, and a methodology of competitive support, a methodology especially important where there are competing commitments. There are also increasingly common identifications of methodological bias in, along with failures to replicate, studies reporting unconscious controls in decision, social priming—as there have been in perception, learning, problem solving, etc. The literature critique has provided evidence taken as reducing, and in some cases eliminating, a role for conscious controls—a position consistent with that ideology out of behaviourism into cognitivism. It is an ideological position that fails to recognize the fundamental distinction between theoretical and metaphysical assertions. PMID:24891796

The purpose of these studies was to develop a psychometrically sound measure of shame, guilt, authentic pride, and hubristic pride for use in body and appearance contexts. In Study 1, 41 potential items were developed and assessed for item quality and comprehension. In Study 2, a panel of experts (N=8; M=11, SD=6.5 years of experience) reviewed the scale and items for evidence of content validity. Participants in Study 3 (n=135 males, n=300 females) completed the BASES and various body image, personality, and emotion scales. A separate sample (n=155; 35.5% male) in Study 3 completed the BASES twice using a two-week time interval. The BASES subscale scores demonstrated evidence for internal consistency, item-total correlations, concurrent, convergent, incremental, and discriminant validity, and 2-week test-retest reliability. The 4-factor solution was a good fit in confirmatory factor analysis, reflecting body-related shame, guilt, authentic and hubristic pride subscales of the BASES. The development and validation of the BASES may help advance body image and self-conscious emotion research by providing a foundation to examine the unique antecedents and outcomes of these specific emotional experiences.

The present study examined the relationships between dysregulations in self-conscious emotions and psychopathology in clinically referred children and adolescents. For this purpose, parent-, teacher-, and self-report Achenbach System of Empirically Based Assessment data of 1000 youth aged 4-18 years was analyzed as this instrument not only provides information on the intensity levels of lack of guilt, guilt, and shame, but also on the severity of various types of psychopathology. The results first of all indicated that dysregulations of self-conscious emotions were more common in this clinical sample than in the general population. Further, a consistent pattern was found with regard to the relationships between self-conscious emotions and childhood psychopathology. That is, lack of guilt was predominantly associated with oppositional defiant and conduct (i.e., externalizing) problems, while guilt and shame were primarily linked with affective and anxiety (i.e., internalizing) problems. By and large, these findings confirm what has been found in non-clinical youth, and suggest that self-conscious emotions play a small but significant role in the psychopathology of children and adolescents.

The clinical evaluation of consciousness in disorder of consciousness (DOC) patients based on their exhibited behavior is difficult and remains erroneous in many cases. Recent studies demonstrated different levels of stimulus processing as well as evidence of some level of awareness in sub-groups of these patients. The aim of the current study was to examine the plausibility and challenges of implementing a clinical service for evaluation of consciousness level in DOC patients. Eleven Patients (ages 11-67) diagnosed as being in vegetative or minimal conscious states were included. Functional MRI evaluations included auditory, language, voice familiarity, imagery, and visual tests. In 9 patients auditory-related activation was found, however only in 5 of the subjects was differential activation found for language. Six patients exhibited differential response to their own name. In three patients a response to visual stimuli was identified. In one patient the auditory and linguistic systems were clearly activated in a hierarchical pattern, and moreover willful modulation of brain activity was identified in the imagery test. We discuss the importance of using a wide battery of tests, the difference between our clinical cohort and previous publications, as well as the challenges of clinically implementing this method. Translating novel imaging methods into the clinical evaluation of DOC patients is essential for better diagnosis and may encourage treatment development. © 2013 Elsevier B.V. All rights reserved.

Gender conformity, self-objectification, and body image for sorority and nonsorority women: A closer look.

Sororities have been identified as placing young women at risk for body image concerns due to a focus on traditional gender role norms and objectification of women. This study assessed the relationship between conformity to feminine gender role norms, self-objectification, and body image surveillance among undergraduate women. In a random sample of undergraduates, the authors examined data from sorority and nonsorority women. In a random sample of undergraduate women, the authors assessed the impact of traditional feminine gender role norms on self-objectification, body image, and feedback regarding physical appearance for sorority and nonsorority undergraduate women. Three linear regressions were conducted, and only conformity to feminine gender role norms contributed significantly in each regression model. Regardless of sorority membership, conformity to feminine gender role norms was found to significantly contribute to increased body consciousness, negative body image, and feedback on physical appearance.

Activation of sensory cortex by imagined genital stimulation: an fMRI analysis

Wise, Nan J.; Frangos, Eleni; Komisaruk, Barry R.

2016-01-01

Background During the course of a previous study, our laboratory made a serendipitous finding that just thinking about genital stimulation resulted in brain activations that overlapped with, and differed from, those generated by physical genital stimulation. Objective This study extends our previous findings by further characterizing how the brain differentially processes physical ‘touch’ stimulation and ‘imagined’ stimulation. Design Eleven healthy women (age range 29–74) participated in an fMRI study of the brain response to imagined or actual tactile stimulation of the nipple and clitoris. Two additional conditions – imagined dildo self-stimulation and imagined speculum stimulation – were included to characterize the effects of erotic versus non-erotic imagery. Results Imagined and tactile self-stimulation of the nipple and clitoris each activated the paracentral lobule (the genital region of the primary sensory cortex) and the secondary somatosensory cortex. Imagined self-stimulation of the clitoris and nipple resulted in greater activation of the frontal pole and orbital frontal cortex compared to tactile self-stimulation of these two bodily regions. Tactile self-stimulation of the clitoris and nipple activated the cerebellum, primary somatosensory cortex (hand region), and premotor cortex more than the imagined stimulation of these body regions. Imagining dildo stimulation generated extensive brain activation in the genital sensory cortex, secondary somatosensory cortex, hippocampus, amygdala, insula, nucleus accumbens, and medial prefrontal cortex, whereas imagining speculum stimulation generated only minimal activation. Conclusion The present findings provide evidence of the potency of imagined stimulation of the genitals and that the following brain regions may participate in erogenous experience: primary and secondary sensory cortices, sensory-motor integration areas, limbic structures, and components of the ‘reward system’.

Chasing the Rainbow: The Non-conscious Nature of Being.

PubMed

Oakley, David A; Halligan, Peter W

2017-01-01

Despite the compelling subjective experience of executive self-control, we argue that "consciousness" contains no top-down control processes and that "consciousness" involves no executive, causal, or controlling relationship with any of the familiar psychological processes conventionally attributed to it. In our view, psychological processing and psychological products are not under the control of consciousness. In particular, we argue that all "contents of consciousness" are generated by and within non-conscious brain systems in the form of a continuous self-referential personal narrative that is not directed or influenced in any way by the "experience of consciousness." This continuously updated personal narrative arises from selective "internal broadcasting" of outputs from non-conscious executive systems that have access to all forms of cognitive processing, sensory information, and motor control. The personal narrative provides information for storage in autobiographical memory and is underpinned by constructs of self and agency, also created in non-conscious systems. The experience of consciousness is a passive accompaniment to the non-conscious processes of internal broadcasting and the creation of the personal narrative. In this sense, personal awareness is analogous to the rainbow which accompanies physical processes in the atmosphere but exerts no influence over them. Though it is an end-product created by non-conscious executive systems, the personal narrative serves the powerful evolutionary function of enabling individuals to communicate (externally broadcast) the contents of internal broadcasting. This in turn allows recipients to generate potentially adaptive strategies, such as predicting the behavior of others and underlies the development of social and cultural structures, that promote species survival. Consequently, it is the capacity to communicate to others the contents of the personal narrative that confers an evolutionary advantage-not the

There Are Conscious and Unconscious Agendas in the Brain and Both Are Important—Our Will Can Be Conscious as Well as Unconscious

2012-01-01

I have been asked to write a few words on consciousness in this editorial issue. My thoughts on consciousness will focus on the relation between consciousness and will. Consciousness is not an epiphenomenon as some people believe—it is not a psychological construct either. Consciousness is a brain function. With deeper thought it is even more than that—a brain state. Writing this, I am in a conscious state, I hope at least. In every day philosophy, a close connection of consciousness with will is ventured, and is expressed in the term “conscious free will”. However, this does not mean that our will is totally determined and not free, be it conscious or unconscious. Total determinists postulate total freedom from nature in order to speak of free will. Absolute freedom from nature is an a priori impossibility; there is no way to escape from nature. However, we have relative freedom, graded freedom, freedom in degrees, enabling us to make responsible decisions and be captains of our own destiny. We are not totally determined. We can upregulate our degrees of freedom by self-management or we can downregulate them by self-mismanagement. In the present communication consciousness and the unconscious are discussed in their various aspects and interactions. PMID:24961200

A Decolonizing Methodology for Health Research on Female Genital Cutting.

PubMed

Werunga, Jane; Reimer-Kirkham, Sheryl; Ewashen, Carol

2016-01-01

In this article, critical perspectives including postcolonial feminism, African feminism, and intersectionality are presented as having decolonizing methodological potential whereby the Western narrative surrounding the practice of female genital cutting, particularly in the context of migration, is reexamined. In addition, multiple intersecting influences on affected women's realities are accounted for and a critical consciousness that serves to inform praxis, address social determinants of health, and promote health equity is encouraged. The inclusion of an African feminist perspective, a traditionally marginalized critical perspective, serves to further decolonize some long-held erroneous beliefs about the sexuality, subjectivity, and embodiment of the African woman.

Negative, but not positive emotional images modulate the startle response independent of conscious awareness.

PubMed

Reagh, Zachariah M; Knight, David C

The emotional response to a threat is influenced by the valence of other stimuli in the environment. This emotional modulation of the threat-elicited response occurs even when negative valence stimuli are not consciously perceived. Relatively little prior research has investigated whether nonconsciously perceived positive valence stimuli modify the response to a threat, and the work that has been completed is in need of additional rigorous testing of stimulus and valence perception. The current study presented images of negative, neutral, and positive valence (1,000 ms and 17 ms durations), followed by a mask. A startle probe (100 dB whitenoise) was presented during 33% of each trial type while eyeblink electromyography (EMG) and skin conductance response (SCR) were measured. During the study, participants rated the emotional content of each image to assess valence perception. Participants accurately classified the valence of 1,000 ms images, but not 17 ms images. Further, participants performed at chance levels on an independent postexperimental forced-choice perception task using 17 ms masked images, indicating they were unable to perceive the valence and content of these images. Greater EMG and SCR were elicited by the startle probe during perceived and unperceived negative images compared to perceived and unperceived positive and neutral images. In addition, perceived, but not unperceived positive images diminished startle responses. The current findings suggest that images of negative valence potentiate the startle response in the absence of conscious stimulus perception. However, the attenuation of the startle response by positive images appears to require perception of the emotional valence of an image. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Female Genital Mutilation Reconstruction: A Preliminary Report.

Chang, Catherine S; Low, David W; Percec, Ivona

Female genital mutilation (FGM) is internationally recognized as a violation of human rights. Though rarely discussed, FGM is prevalent, affecting hundreds of millions of females worldwide. We believe that is important for plastic surgeons to be informed and prepared to address the surgical and emotional needs of these women. We present our experience on treatment of women subjected to FGM. Three consecutive patients were treated by our clitoral restoration procedure. The procedure involves conscious sedation and involves wide release of scar tissue around the labia majora and clitoris. Labial flaps are elevated and secured down to the periosteum and the clitoris is allowed to remucosalize. Three females with grade II mutilation were treated. The average age was 32.3-years-old and the average follow up was 305 days. All patients self-reported improved sexual function and decreased embarrassment with their partners. And all recommended the treatment to other women subjected to FGM. FGM is a violation of the basic rights of women and children. Plastic surgeons can help these women restore their physical and psychological sense of well-being by providing effective reconstructive options. Our goal is to raise awareness of this problem and describe a simple yet effective treatment for women that have been subject to FGM. 5. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Troubles with self-consciousness. Jervis on introspection and defense mechanisms.

PubMed

Marraffa, Massimo

2012-01-01

Building on Sigmund Freud, Ernesto de Martino and cognitive sciences, Giovanni Jervis has outlined a view of introspective consciousness as primarily an activity of narrative re-appropriation of the outputs of the unconscious cognitive processing, emphasizing that such an activity is ruled by the primary need to construct an identity that is valid as much as possible. Thus Jervis has originally pursued an integration between the anti-introspectionist tradition in cognitive sciences and the psychodynamic investigation on defense mechanisms. This paper outlines Jervis' attempt to integrate these two traditions, and shows that it fits very well with recent developments of the theory-theory approach to self-knowledge.

2016-06-20

The main aim of this study is to demonstrate that private self-consciousness (SC) and core self-evaluations (CSEs) influence their formation, via the perceived feasibility and desirability of entrepreneurship or in interaction with it. Two hundred and sixteen students, from a university, an engineering college and a management school, participated in a survey questionnaire which measured these variables as well as controlled factors (e.g. entrepreneurship education, presence of entrepreneurs in their close social network). The results confirm that CSEs have a positive effect on feasibility and desirability (p < .001) which mediate their effect on intention (p < .007). They also show that private SC has a positive direct effect on intention (p < .001). Additionally, the positive interaction effects of desirability and feasibility and public SC and feasibility on intention are highlighted (p < .05). Unexpectedly, none of the hypothesized moderation effects of private SC were corroborated. The convergence of these results with prior research, the limitations of the study and practical implications are discussed.

Ictal alterations of the level of general awareness and subjective content of consciousness play a pivotal role in the clinical phenomenology of epilepsy, and reflect the pathological involvement of different neurobiological substrates. However, no self-reported measures have been proposed for patients experiencing altered conscious states during seizures. This study describes the development and validation of a new scale for the quantitative assessment of the level and content of ictal consciousness, the Ictal Consciousness Inventory (ICI). The ICI is a 20-item questionnaire generated on the basis of interviews with patients, literature review, and consultation with experts. It was tested on a sample of 110 patients attending three different epilepsy clinics in Northern Italy, who also completed standardized clinical scales. Standard psychometric methods were used to demonstrate that this scale satisfies criteria for acceptability, reliability, and validity. The ICI is proposed as a user-friendly and clinically sound instrument for the measurement of ictal alterations of consciousness in patients with epilepsy.

2010-01-01

Purpose of review We discuss the problems of evidence-based neurorehabilitation in disorders of consciousness, and recent functional neuroimaging data obtained in the vegetative state and minimally conscious state. Recent findings Published data are insufficient to make recommendations for or against any of the neurorehabilitative treatments in vegetative state and minimally conscious state patients. Electrophysiological and functional imaging studies have been shown to be useful in measuring residual brain function in noncommunicative brain-damaged patients. Despite the fact that such studies could in principle allow an objective quantification of the putative cerebral effect of rehabilitative treatment in the vegetative state and minimally conscious state, they have so far not been used in this context. Summary Without controlled studies and careful patient selection criteria it will not be possible to evaluate the potential of therapeutic interventions in disorders of consciousness. There also is a need to elucidate the neurophysiological effects of such treatments. Integration of multimodal neuroimaging techniques should eventually improve our ability to disentangle differences in outcome on the basis of underlying mechanisms and better guide our therapeutic options in the challenging patient populations encountered following severe acute brain damage.

Objective Caring for a family member with schizophrenia often results in high degrees of self-conscious emotions (shame and guilt/self -blame), burden, and other serious mental health consequences. Research suggests that ethnic and cultural factors strongly influence the manner in which family members respond to mental illness. Research further indicates that certain cultural practices and values (spirituality, collectivism) may assist family members in coping with the self-conscious emotions and burden associated with caregiving. With this in mind, we have developed a family focused, culturally-informed treatment for schizophrenia (CIT-S). Method Using a sample of 113 caregivers of patients with schizophrenia (60% Hispanic, 28.2% Caucasian, 8% African American and 3.8% “Other”), we assessed the ability of CIT-S to reduce self-conscious emotions and caregiver burden above and beyond a three-session psychoeducation (PSY-ED) control condition. We further examined whether self-conscious emotions mediated the relationship between treatment type and caregiver burden. Results In line with expectations, CIT-S was found to outperform PSY-ED in reducing guilt/self-blame and caregiver burden. Furthermore, consistent with hypotheses, reductions in guilt/self-blame were found to mediate the changes observed between treatment type and caregiver burden. While caregivers in both treatment groups demonstrated significant post treatment reductions in shame, CIT-S was not found to outperform PSY-ED in reducing levels of this construct. Conclusions Results suggest that caregivers of patients with schizophrenia may respond well to a treatment that specifically taps in to their cultural beliefs, values, and behaviors in helping them cope with schizophrenia in a loved one. Study implications and future directions are discussed. PMID:26654115

Many sexual psychophysiologic studies have failed to find differences in physiologic genital arousal between women with and those without sexual dysfunction. However, differences in self-reported (ie, perceived) measures of genital responses between these 2 groups of women have been noted. To determine whether women with and without sexual dysfunction differ on measures of physiologic and perceived genital arousal based on type of analytic technique used, to explore differences in perceived genital arousal, and to assess the relation between physiologic and perceived genital arousal. Data from 5 studies (N = 214) were used in this analysis. Women were categorized into 3 groups: women with arousal-specific sexual dysfunction (n = 40), women with decreased sexual function (n = 72), and women who were sexually functional (n = 102). Women viewed an erotic film while their physiologic genital arousal was measured using a vaginal photoplethysmograph. After watching the film, women completed a self-report measure of perceived genital arousal. There were differences in vaginal pulse amplitude (VPA) levels and association of VPA with perceived genital sensations based on level of sexual function. Commonly used methods of analysis failed to identify significant differences in VPA among these groups of women. When VPA data were analyzed with hierarchical linear modeling, significant differences emerged. Notably, women with arousal-specific dysfunction exhibited lower VPA than sexually functional women at the beginning of the assessment. As the erotic film progressed, women with arousal-specific dysfunction became aroused at a faster rate than sexually functional women, and these 2 groups ultimately reached a similar level of VPA. Sexually functional women reported the highest levels of perceived genital responses among the 3 groups of women. No significant relation between VPA and perceived genital arousal emerged. Women's perception of their genital responses could play

De Sousa, Avinash

2013-01-01

The study of consciousness has today moved beyond neurobiology and cognitive models. In the past few years, there has been a surge of research into various newer areas. The present article looks at the non-neurobiological and non-cognitive theories regarding this complex phenomenon, especially ones that self-psychology, self-theory, artificial intelligence, quantum physics, visual cognitive science and philosophy have to offer. Self-psychology has proposed the need to understand the self and its development, and the ramifications of the self for morality and empathy, which will help us understand consciousness better. There have been inroads made from the fields of computer science, machine technology and artificial intelligence, including robotics, into understanding the consciousness of these machines and their implications for human consciousness. These areas are explored. Visual cortex and emotional theories along with their implications are discussed. The phylogeny and evolution of the phenomenon of consciousness is also highlighted, with theories on the emergence of consciousness in fetal and neonatal life. Quantum physics and its insights into the mind, along with the implications of consciousness and physics and their interface are debated. The role of neurophilosophy to understand human consciousness, the functions of such a concept, embodiment, the dark side of consciousness, future research needs and limitations of a scientific theory of consciousness complete the review. The importance and salient features of each theory are discussed along with certain pitfalls, if present. A need for the integration of various theories to understand consciousness from a holistic perspective is stressed. PMID:23678242

Consciousness in dolphins? A review of recent evidence.

PubMed

Harley, Heidi E

2013-06-01

For millennia, dolphins have intrigued humans. Scientific study has confirmed that bottlenose dolphins are large-brained, highly social mammals with an extended developmental period, flexible cognitive capacities, and powerful acoustic abilities including a sophisticated echolocation system. These findings have led some to ask if dolphins experience aspects of consciousness. Recent investigations targeting self-recognition/self-awareness and metacognition, constructs tied to consciousness on some accounts, have analyzed the dolphin's ability to recognize itself in a mirror or on a video as well as to monitor its own knowledge in a perceptual categorization task. The current article reviews this work with dolphins and grapples with some of the challenges in designing, conducting, and interpreting these studies as well as with general issues related to studying consciousness in animals. The existing evidence does not provide a convincing case for consciousness in dolphins. For productive scientific work on consciousness in dolphins (and other animals including humans), we need clearer characterizations of consciousness, better methods for studying it, and appropriate paradigms for interpreting outcomes. A current focus on metamemory in animals offers promise for future discovery in this area.

The European Society of Paediatric Radiology Uroradiology Task Force and the ESUR Paediatric Work Group jointly publish guidelines for paediatric urogenital imaging. Two yet unaddressed topics involving patient safety and imaging load are addressed in this paper: renal biopsy in childhood and imaging of the neonatal genital tract, particularly in girls. Based on our thorough review of literature and variable practice in multiple centers, procedural recommendations are proposed on how to perform renal biopsy in children and how to approach the genital tract in (female) neonates. These are statements by consensus due to lack of sufficient evidence-based data. The procedural recommendation on renal biopsy in childhood aims at improving patient safety and reducing the number of unsuccessful passes and/or biopsy-related complications. The recommendation for an imaging algorithm in the assessment of the neonatal genital tract focuses on the potential of ultrasonography to reduce the need for more invasive or radiating imaging, however, with additional fluoroscopy or MRI to be used in selected cases. Adherence to these recommendations will allow comparable data and evidence to be generated for future adaptation of imaging strategies in paediatric uroradiology.

The construct of the "self" is conceived as being fundamental in promoting survival. As such, extensive studies have documented preferential processing of self-relevant stimuli. For example, attributes that relate to the self are better encoded and retrieved, and are more readily consciously perceived. The preferential processing of self-relevant information, however, appears to be especially true for physical (e.g., faces), as opposed to psychological (e.g., traits), conceptions of the self. Here, we test whether semantic attributes that participants judge as self-relevant are further processed unconsciously than attributes that were not judged as self-relevant. In Experiment 1, a continuous flash suppression paradigm was employed with "self" and "non-self" attribute words being presented subliminally, and we asked participants to categorize unseen words as either self-related or not. In a second experiment, we attempted to boost putative preferential self-processing by relation to its physical conception, that is, one's own body. To this aim, we repeated Experiment 1 while administrating acoustic stimuli either close or far from the body, i.e., within or outside peripersonal space. Results of both Experiment 1 and 2 demonstrate no difference in breaking suppression for self and non-self words. Additionally, we found that while participants were able to process the physical location of the unseen words (above or below fixation) they were not able to categorize these as self-relevant or not. Finally, results showed that sounds presented in the extra-personal space elicited a more stringent response criterion for "self" in the process of categorizing unseen visual stimuli. This shift in criterion as a consequence of sound location was restricted to the self, as no such effect was observed in the categorization of attributes occurring above or below fixation. Overall, our findings seem to indicate that subliminally presented stimuli are not semantically processed, at

Chasing the Rainbow: The Non-conscious Nature of Being

PubMed Central

Oakley, David A.; Halligan, Peter W.

2017-01-01

Despite the compelling subjective experience of executive self-control, we argue that “consciousness” contains no top-down control processes and that “consciousness” involves no executive, causal, or controlling relationship with any of the familiar psychological processes conventionally attributed to it. In our view, psychological processing and psychological products are not under the control of consciousness. In particular, we argue that all “contents of consciousness” are generated by and within non-conscious brain systems in the form of a continuous self-referential personal narrative that is not directed or influenced in any way by the “experience of consciousness.” This continuously updated personal narrative arises from selective “internal broadcasting” of outputs from non-conscious executive systems that have access to all forms of cognitive processing, sensory information, and motor control. The personal narrative provides information for storage in autobiographical memory and is underpinned by constructs of self and agency, also created in non-conscious systems. The experience of consciousness is a passive accompaniment to the non-conscious processes of internal broadcasting and the creation of the personal narrative. In this sense, personal awareness is analogous to the rainbow which accompanies physical processes in the atmosphere but exerts no influence over them. Though it is an end-product created by non-conscious executive systems, the personal narrative serves the powerful evolutionary function of enabling individuals to communicate (externally broadcast) the contents of internal broadcasting. This in turn allows recipients to generate potentially adaptive strategies, such as predicting the behavior of others and underlies the development of social and cultural structures, that promote species survival. Consequently, it is the capacity to communicate to others the contents of the personal narrative that confers an evolutionary

This review studies rationale and outcome of vulvovaginal aesthetic surgery. Discuss procedures designed to alter genital appearance and function; investigate sexual, philosophical, and ethical issues; examine outcomes. (i) Medline search of the existing literature utilizing terms labiaplasty, clitoral hood reduction, hymenoplasty (HP), vaginoplasty (VP), perineoplasty (PP), female genital surgery, sexual satisfaction/body image, and anterior/posterior colporrhaphy; (ii) references from bibliographies of papers found through the literature search and in the author's reading of available literature. (i) Demographics and psychosexual dynamics of women requesting female genital plastic/cosmetic surgery; (ii) overall and sexual satisfaction of subjects undergoing these procedures. The majority of studies regarding patient satisfaction and sexual function after vaginal aesthetic and functional plastic procedures report beneficial results, with overall patient satisfaction in the 90-95% range, sexual satisfaction over 80-85%. These data are supported by outcome data from nonelective vaginal support procedures. Complications appear minor and acceptable to patients. There are little data available regarding outcomes and satisfaction of HP, or function during the rigors of subsequent vaginal childbirth, although the literature contains no case reports of labiaplasty disruption during parturition. Women requesting labiaplasty and reduction of their clitoral hoods do so for both cosmetic and functional (chafing, interference with coitus, interference with athletic activities, etc.) reasons, while patients requesting VP and/or PP do so in order to increase friction and sexual satisfaction, occasionally for aesthetic reasons. Patients appear generally happy with outcomes. The majority of patients undergoing genital plastic surgery report overall satisfaction and subjective enhancement of sexual function and body image, but the literature is retrospective.

Conroy, David E; Ram, Nilam; Pincus, Aaron L; Rebar, Amanda L

Self-conscious emotions play a role in regulating daily achievement strivings, social behavior, and health, but little is known about the processes underlying their daily manifestation. Emerging adults (n = 182) completed daily diaries for eight days and multilevel models were estimated to evaluate whether, how much, and why their emotions varied from day-to-day. Within-person variation in authentic pride was normally-distributed across people and days whereas the other emotions were burst-like and characterized by zero-inflated, negative binomial distributions. Perceiving social interactions as generally communal increased the odds of hubristic pride activation and reduced the odds of guilt activation; daily communal behavior reduced guilt intensity. Results illuminated processes through which meaning about the self-in-relation-to-others is constructed during a critical period of development.

Disorders/differences of sex development (DSD) refer to congenital conditions with atypical sex development and are associated with psychosexual issues. The aim of this study was to assess body image and self-esteem across the DSD spectrum and to study the impact of diagnosis and mediating characteristics. Data collection was part of dsd-LIFE, a cross-sectional study conducted by 14 European expert clinics on wellbeing and health care evaluation of adults diagnosed with DSD. Main outcome measures in the present analyses were the Body Image Scale and Rosenberg Self-Esteem Scale. Additional data were obtained on treatments, openness, body embarrassment, sexual satisfaction, anxiety, and depression. The participating sample (n = 1,040) included 226 classified as Congenital Adrenal Hyperplasia, 225 as Klinefelter Syndrome, 322 as Turner Syndrome, and 267 as conditions with 46,XY karyotype. Many participants had received hormonal and surgical treatments. Participants scored lower on body image and self-esteem compared to control values, whereas each diagnosis showed different areas of concern. Limited openness, body embarrassment, and sexual issues were frequently reported. Overall body satisfaction was associated with BMI, hormone use, openness, body embarrassment, anxiety, and depression; genital satisfaction with age at diagnosis, openness, sexual satisfaction, and body embarrassment. Body embarrassment, anxiety, and depression predicted lower self-esteem. While each DSD showed specific issues related to body image and self-esteem, our findings indicate that the related factors were similar across the conditions. Clinical care on this subject could be improved by giving specific attention to factors like openness, body embarrassment, sexuality, anxiety, and depression.

Minimally conscious state or cortically mediated state?

PubMed

Naccache, Lionel

2018-04-01

Durable impairments of consciousness are currently classified in three main neurological categories: comatose state, vegetative state (also recently coined unresponsive wakefulness syndrome) and minimally conscious state. While the introduction of minimally conscious state, in 2002, was a major progress to help clinicians recognize complex non-reflexive behaviours in the absence of functional communication, it raises several problems. The most important issue related to minimally conscious state lies in its criteria: while behavioural definition of minimally conscious state lacks any direct evidence of patient's conscious content or conscious state, it includes the adjective 'conscious'. I discuss this major problem in this review and propose a novel interpretation of minimally conscious state: its criteria do not inform us about the potential residual consciousness of patients, but they do inform us with certainty about the presence of a cortically mediated state. Based on this constructive criticism review, I suggest three proposals aiming at improving the way we describe the subjective and cognitive state of non-communicating patients. In particular, I present a tentative new classification of impairments of consciousness that combines behavioural evidence with functional brain imaging data, in order to probe directly and univocally residual conscious processes.

[Functional pathophysiology of consciousness].

Consciousness (Latin conscientia "moral conscience"), according to the English philosopher John Locke (1632-1704) [103], is the awareness of all that occurs in the mind of a person, whereas the American philosopher John Searle (2000) defined it as "inner qualitative, subjective states and processes of awareness". In modern science it is defined as a continuous state of full awareness of the Self and one's relationship to the external and internal environment, describing the degree of wakefulness in which an organism recognizes stimuli. This widely discussed biological term for complex neuronal processes that allow an individuum to recognize itself and its environment and to act accordingly, has been and still is the subject of much research in philosophy and natural/neuroscience. Its definition is often used for awareness and recognition, too. While the Egyptians in the papyrus Edwin Smith already recognized the brain as the seat of consciousness, René Descartes (1644 [36]) believed its special structure should be "a small gland in the middle", but the anatomical structures and physiological processes involved in consciousness were elucidated only in the middle of the 20th century. Neuronal substrates include several functional networks that are hierarchically organized and cooperate functionally. The lowest level is the mesencephalic formatio reticularis and its projections to the thalamus that were identified als ascending reticular system (ARAS) by the classical experiments of Moruzzi and Magoun, whereas later analyses of patients with impaired consciousness provided further insights. The mesencephalic ARAS as motor of the function of higher structures projects 1. via the reticular thalamus diffusely to the cortex, 2. via hypothalamus to the basal forebrain and limbic system, and 3. to the medial raphe of the brainstem and locus coeruleus and their diffuse cortical projections. The reticular system is stimulated directly and indirectly via numerous collaterals

Topical or systemic antiviral drugs reduce the duration of genital herpes recurrences but may not always alleviate functional symptoms. To assess the efficacy and safety of oxygenated glycerol triesters-based CS21 barrier genital gel(®) vs. topical aciclovir and placebo (vehicle) in resolving functional symptoms and in healing of genital herpes recurrences. A prospective randomized controlled, investigator-blinded trial of CS21 barrier genital gel(®) vs. topical aciclovir (reference treatment) and placebo (vehicle) was designed. The primary endpoint was the cumulative score of four herpes-related functional symptoms (pain, burning, itching and tingling sensations). Secondary endpoints included objective skin changes (erythema, papules, vesicles, oedema, erosion/ulceration, crusts), time to heal, local tolerance and overall acceptability of the treatment as reported by a self-administered questionnaire. Overall, 61 patients were included. CS 21 barrier genital gel(®) was significantly more efficient than topical aciclovir and vehicle for subjective symptoms and pain relief in genital herpes recurrences; additionally, time to heal was significantly shorter with CS 21 than with vehicle, whereas no significantly difference was observed between patients receiving topical aciclovir and vehicle. The treatments under investigation were well tolerated and the adverse events were comparable in the three treatment groups. Overall, these results support the interest of using of CS 21 barrier genital gel(®) in symptomatic genital herpes recurrences. Accordingly, this product offers a valuable alternative in topical management of recurrent genital herpes. © 2013 European Academy of Dermatology and Venereology.

Toward a cultural consciousness of self in relationship: from "us and them" to "we".

Ventres, William; Haq, Cynthia

2014-10-01

While skills and techniques can help family physicians and other health professionals achieve basic competence in working across cultural and social boundaries, perhaps their most important tasks are those directed inward toward attitudes, beliefs, and capacities for self-exploration. This essay links the practice and teaching of cross-cultural medicine to clinicians' and educators' exploration of their own self- consciousness. The more they are willing to explore the unfamiliar within themselves, the more emotionally and psychologically comfortable they can become in dealing with the joys and challenges inherent in cross-cultural medicine. Several practices can foster this development of a sense of self in relationship with others. As health professionals and medical educators recognize and promote an awareness of self in relationship, they can enhance their personal and professional roles to become more effective advocates of equity and social justice in every clinical encounter.

Genital herpes simplex.

Genital herpes is a sexually transmitted disease caused by the herpes simplex virus. Following the initial infection the virus becomes latent in the sacral ganglia. Approximately 80% of patients are then subject to milder but unpredictable recurrences and may shed the virus even when they are asymptomatic. The disorder causes concern because genital herpes in the mother can result in rare but catastrophic neonatal infection and because of a possible association between genital herpes and cancer of the cervix. No effective treatment is as yet available. Weekly monitoring for virus by cervical culture from 32 weeks' gestation is recommended for women with a history of genital herpes and for those whose sexual partner has such a history.

Coevolution of female and male genital components to avoid genital size mismatches in sexually dimorphic spiders.

Lupše, Nik; Cheng, Ren-Chung; Kuntner, Matjaž

2016-08-17

In most animal groups, it is unclear how body size variation relates to genital size differences between the sexes. While most morphological features tend to scale with total somatic size, this does not necessarily hold for genitalia because divergent evolution in somatic size between the sexes would cause genital size mismatches. Theory predicts that the interplay of female-biased sexual size dimorphism (SSD) and sexual genital size dimorphism (SGD) should adhere to the 'positive genital divergence', the 'constant genital divergence', or the 'negative genital divergence' model, but these models remain largely untested. We test their validity in the spider family Nephilidae known for the highest degrees of SSD among terrestrial animals. Through comparative analyses of sex-specific somatic and genital sizes, we first demonstrate that 99 of the 351 pairs of traits are phylogenetically correlated. Through factor analyses we then group these traits for MCMCglmm analyses that test broader correlation patterns, and these reveal significant correlations in 10 out of the 36 pairwise comparisons. Both types of analyses agree that female somatic and internal genital sizes evolve independently. While sizes of non-intromittent male genital parts coevolve with male body size, the size of the intromittent male genital parts is independent of the male somatic size. Instead, male intromittent genital size coevolves with female (external and, in part, internal) genital size. All analyses also agree that SGD and SSD evolve independently. Internal dimensions of female genitalia evolve independently of female body size in nephilid spiders, and similarly, male intromittent genital size evolves independently of the male body size. The size of the male intromittent organ (the embolus) and the sizes of female internal and external genital components thus seem to respond to selection against genital size mismatches. In accord with these interpretations, we reject the validity of the

This study aimed to explore the relationships between gender-role socialization, objectified body consciousness and quality of life in breast cancer (BC) survivors with body image (BI) disturbance post-treatment. A total of 150 BC survivors participating in an ongoing randomized clinical trial of a group psychotherapy intervention for BI-related concerns completed a baseline battery of standardized measures including the following: Body Image Scale (BIS), Body Image after Breast Cancer Questionnaire (BIBCQ), Objectified Body Consciousness Scale (OBCS) measuring Body Shame and Surveillance, Gender-Role Socialization Scale (GRSS) measuring internalization of traditional gender roles and attitudes and the Functional Assessment of Cancer Therapy-Breast Quality-of-Life Instrument (FACT-B). Correlational analyses were conducted between the two BI questionnaires, the two primary psychosocial variables GRSS and OBCS, and FACT-B. Path analysis was conducted on a proposed theoretical model delineating pathways between the two primary psychosocial variables and BI disturbance. Significant positive correlations were found between the two BI scales and (a) GRSS (average r = 0.53, p < 0.000), (b) Body Shame (average r = 0.53, p < 0.000) and Surveillance (average r = 0.48, p < 0.000). The BIS and BIBCQ were negatively associated with the FACT-B (r = -0.62, -0.73, respectively; p < 0.000). Results from the path analysis demonstrated support for the proposed model. Breast cancer survivors who endorsed greater internalization of traditional gender roles and attitudes, who engaged in greater self-surveillance and experienced greater body shame, reported greater BI disturbance and poorer quality of life post-treatment. Women with these predispositions are likely to be more vulnerable for psychological distress and may experience poorer adjustment after BC treatment. Copyright © 2013 John Wiley & Sons, Ltd.

Persistent genital arousal disorder (PGAD) is an understudied condition characterized by unwanted physiologic genital arousal in the absence of subjective sexual arousal. Markos and Dinsmore (Int J STD AIDS 2013;24:852-858) theorized that PGAD shares a number of similarities with vulvodynia (unexplained chronic vulvar pain [CVP]), including symptom characteristics and comorbidities. To compare medical histories, symptom characteristics, pain characteristics, and daily functioning among women with persistent genital pain (PGA) (n = 42), painful PGA (n = 37), and CVP (n = 42) symptoms. An online cross-sectional survey was conducted from October 2015 through April 2016. Self-report measures of symptoms, diagnosed medical conditions, pain characteristics (McGill Pain Questionnaire), catastrophizing (Pain Catastrophizing Scale), and daily functioning (Functional Status Questionnaire) were collected. All 3 groups reported similar medical diagnoses and high frequencies of other chronic pelvic pain conditions. Women in all 3 groups reported comparable ages at symptom onset and timing of symptom expression (ie, constant vs intermittent). Women in the 2 PGA groups reported significantly greater feelings of helplessness than women in the CVP group. Women in the painful PGA and CVP groups endorsed significantly more sensory terms to describe their symptoms compared with women in the PGA group, whereas women in the painful PGA group reported significantly more affective terms to describe their symptoms compared with women in the CVP group. Women in the 2 PGA groups reported that their symptoms interfered significantly with most areas of daily functioning. Given the similarities between PGA and CVP symptoms, women with PGA may benefit from similar assessment, treatment, and research approaches. Limitations of the present study include its sole use of self-report measures; the presence of PGA or CVP symptoms was not confirmed by clinical assessment. However, the anonymous

Clitoral reconstruction following female genital mutilation/cutting (FGM/C) is a new surgical technique reported to be a feasible and effective strategy to reduce clitoral pain, improve sexual pleasure, and restore a vulvar appearance similar to uncircumcised women. However, data on safety, care offered, and evaluation of sexual and pain outcomes are still limited. This study aims to present the care offered and clinical outcomes of two women who received multidisciplinary care, including psychosexual treatment, with clitoral reconstruction. We report their long-term outcomes, and the histology of the removed periclitoral fibrosis. We report the cases of two women with FGM/C types II and III who requested clitoral reconstruction for different reasons. One woman hoped to improve her chronic vulvar pain, as well as improve her sexual response. The other woman requested surgery due to a desire to reverse a procedure that was performed without her consent, and a wish to have a genital appearance similar to non infibulated women. They both underwent psychosexual evaluation and therapy and surgery. The histology of the periclitoral fibrosis removed during surgery was analyzed. At 1-year postoperatively, the first woman reported complete disappearance of vulvar pain and improved sexual pleasure, including orgasm. Our second patient also described improved sexuality at 1-year follow-up (increased sexual desire, lubrication, vulvar pleasure, and sensitiveness), which she attributed to a better self body image and confidence. Both women reported feeling satisfied, happy, and more beautiful. We show a positive outcome in pain reduction and improved sexual function, self body image, and gender after psychosexual therapy and clitoral reconstruction. More evidence is needed about clitoral reconstruction to develop guidelines on best practices. Until research is conducted that rigorously evaluates clitoral reconstruction for its impact on pain and sexuality, we advise always

Kaminsky, A; Sperling, H

In addition to epididymitis and testicular torsion, emergencies of the external genital are rare. Rapid diagnosis and therapy are essential so that immediate therapy can be provided, which is important for survival (Fournier gangrene) of the patient or for the preservation of erectile function (priapism and penile fracture). A detailed patient history and clinical examination are generally sufficient for correct diagnosis. Under certain circumstances, it might be useful to perform ultrasound, computed tomography scan or magnetic resonance imaging or retrograde urethrography. A urine analysis is obligatory. In case of penetrating injuries and genital trauma in females, additional imaging should be performed because these are often associated with concomitant injuries of the rectum, vagina, or bladder. Special cases are gunshot wounds, in which caliber and type of weapon play an important role for the degree of damage, and animal or human bites. For animal bites, the risk for rabies infection and in case of a human bite the risk for transmission of HIV and hepatitis should be taken into consideration and post-exposure prophylaxis should possibly be offered.

Teaching ecosystem and environment and its effect on the environmental consciousness of grade 9 students: A preliminary self study

This research is a self-study research. The aims of the research were to reflect a teaching and learning process in a classroom on the topic of ecosystem and environment; a part of basic science subjects, and investigate the effect of a teaching on environmental consciousness. As a self-study research, the first author was a practitioner who taught grade ninth students classroom consisting of 50 students of an extra-large high school in Bangkok during the second semester of 2016 academic year. Data of the teaching method was collected by using teaching logs and critical friend interviews. The data was qualitatively analyzed by using content analysis. The effectiveness of teaching the environmental consciousness was investigated by using a 5 level-rating scale the environmental consciousness questionnaire. The questionnaire was administered three times, at the beginning of the semester, before and after learning the topic ecosystem and environment. The data was statistically analyzed by mean, standard deviation, and analysis of variance (one -way ANOVA). The results were indicated that: 1. The teacher directed all classroom activities, used power point to show the contents and pictures while she was talking and students were listening. The teacher often asked questions and mostly assigned students to work alone and sometimes in a group. Students only studied in the classroom. After learning, the students were assigned to do work sheets alone such as searching for information and making reports. 2. The grade 9 students had no significantly different level of the environmental consciousness comparing between the beginning of the semester (x ¯ = 3.33), before learning (x ¯ = 3.35) and after learning (x ¯ = 3.40). It can be concluded that this teaching and learning process cannot promote the environmental consciousness. This study was a preliminary study, the results indicate the need for change of teaching practice in the classroom.

Self-consciousness was compared in 17 elderly (aged 65-89 years old) persons with cognitive impairment without dementia and 17 patients with vascular dementia. Neurocognitive functions and mental health complaints were evaluated. Neuropsychological assessment included evaluation of higher psychological functions, such as attention, memory, conceptualization, gnosis (optic, acoustic), manual skill, speech. Older persons with cognitive impairment assessed their neurocognitive functions adequately. Patients with vascular dementia usually denied cognitive deficit or explained it as a result of aging. Regardless of physical health, older persons with cognitive impairment have active attitude to aging. They could find ways of compensation of cognitive deficits without assistance. Patients with vascular dementia could not compensate their cognitive deficit even with support.

Consciousness, Cognition and the Cognitive Apparatus in the Vedānta Tradition

PubMed Central

Balasubramanian, R.

2011-01-01

A human being is a complex entity consisting of the Self (also known as Consciousness), mind, senses and the body. The Vedānta tradition holds that the mind, the senses and the body are essentially different from the Self or Consciousness. It is through consciousness that we are able to know the things of the world, making use of the medium of the mind and the senses. Furthermore, the mind, though material, is able to reveal things, borrowing the light from consciousness. From the phenomenological point of view, we have to answer the following questions: how does one know the mind/the mental operations/the cogitations of the mind? Does the mind know itself? Is it possible? There is, again, the problem of the intentionality of consciousness. Is consciousness intentional? According to Vedānta, consciousness by its very nature is not intentional, but it becomes intentional through the mind. The mind or the ego is not part of the consciousness; on the contrary, it is transcendent to consciousness. It is difficult to spell out the relation between consciousness and the mind. How does consciousness, which is totally different from the mind, get related to the mind in such a way that it makes the latter capable of comprehending the things of the world? The Vedānta tradition provides the answer to this question in terms of the knower-known relation. Consciousness is pure light, self-luminous by its very nature, that is, although it reveals other objects, it is not revealed by anything else. When Sartre describes it as nothingness, bereft of even ego, it is to show that it is pure light revealing objects outside it. PMID:21694962

Interplay between Narrative and Bodily Self in Access to Consciousness: No Difference between Self- and Non-self Attributes

PubMed Central

Noel, Jean-Paul; Blanke, Olaf; Serino, Andrea; Salomon, Roy

2017-01-01

The construct of the “self” is conceived as being fundamental in promoting survival. As such, extensive studies have documented preferential processing of self-relevant stimuli. For example, attributes that relate to the self are better encoded and retrieved, and are more readily consciously perceived. The preferential processing of self-relevant information, however, appears to be especially true for physical (e.g., faces), as opposed to psychological (e.g., traits), conceptions of the self. Here, we test whether semantic attributes that participants judge as self-relevant are further processed unconsciously than attributes that were not judged as self-relevant. In Experiment 1, a continuous flash suppression paradigm was employed with “self” and “non-self” attribute words being presented subliminally, and we asked participants to categorize unseen words as either self-related or not. In a second experiment, we attempted to boost putative preferential self-processing by relation to its physical conception, that is, one’s own body. To this aim, we repeated Experiment 1 while administrating acoustic stimuli either close or far from the body, i.e., within or outside peripersonal space. Results of both Experiment 1 and 2 demonstrate no difference in breaking suppression for self and non-self words. Additionally, we found that while participants were able to process the physical location of the unseen words (above or below fixation) they were not able to categorize these as self-relevant or not. Finally, results showed that sounds presented in the extra-personal space elicited a more stringent response criterion for “self” in the process of categorizing unseen visual stimuli. This shift in criterion as a consequence of sound location was restricted to the self, as no such effect was observed in the categorization of attributes occurring above or below fixation. Overall, our findings seem to indicate that subliminally presented stimuli are not

Stigma Cues Increase Self-Conscious Emotions and Decrease Likelihood of Attention to Information about Preventing Stigmatized Health Issues

2018-01-01

Health communications are only effective if target audiences actually receive the messages. One potential barrier to effective health communication is the potential stigma of attending to health information, particularly for stigmatizing health issues. The purpose of the present paper was to examine when participants report self-conscious emotions (e.g., shame, embarrassment) in response to health communications, as well as likelihood of reading health information associated with these emotions. Across three studies, participants read information about preventing diseases that are either highly stigmatized or non-stigmatized. Increased accessibility of stigma cues by (a) manipulating the perceived absence vs. presence of others, or (b) measuring lower vs. higher rejection sensitivity resulted in increased self-conscious emotions in response to information about stigmatized health issues. In addition, stigma cues decreased the likelihood of reading information about stigmatized (but not non-stigmatized) health information. Implications for health outcomes and intervention design are discussed. PMID:29809200

Individuals can experience negative emotions (e.g., embarrassment) accompanying self-evaluation immediately after recognizing their own facial image, especially if it deviates strongly from their mental representation of ideals or standards. The aim of this study was to identify the cortical regions involved in self-recognition and self-evaluation along with self-conscious emotions. To increase the range of emotions accompanying self-evaluation, we used facial feedback images chosen from a video recording, some of which deviated significantly from normal images. In total, 19 participants were asked to rate images of their own face (SELF) and those of others (OTHERS) according to how photogenic they appeared to be. After scanning the images, the participants rated how embarrassed they felt upon viewing each face. As the photogenic scores decreased, the embarrassment ratings dramatically increased for the participant's own face compared with those of others. The SELF versus OTHERS contrast significantly increased the activation of the right prefrontal cortex, bilateral insular cortex, anterior cingulate cortex, and bilateral occipital cortex. Within the right prefrontal cortex, activity in the right precentral gyrus reflected the trait of awareness of observable aspects of the self; this provided strong evidence that the right precentral gyrus is specifically involved in self-face recognition. By contrast, activity in the anterior region, which is located in the right middle inferior frontal gyrus, was modulated by the extent of embarrassment. This finding suggests that the right middle inferior frontal gyrus is engaged in self-evaluation preceded by self-face recognition based on the relevance to a standard self.

To estimate the occurrence of and risk factors associated with genital warts in Danish men We conducted a cross-sectional, questionnaire-based study among almost 23 000 men aged 18-45 years, randomly sampled from the general population of Denmark. Data was collected on self-reported clinically diagnosed genital warts, and various lifestyle habits. Ever having had clinically diagnosed genital warts was reported by 7.9% of the men. The median age at first occurrence was 22 years. Genital warts within the previous 12 months were reported by 0.92% of the men, with a peak of 1.83% among men aged 21-24 years. The likelihood of reporting genital warts was strongly correlated with the lifetime number of sex partners (OR 8.0; 95% CI 6.0 to 10.8 for ≥15 partners vs 1-2 partners). Other factors associated with an increased risk for genital warts included ever having smoked and having had other sexually transmitted infections. Almost 8% of Danish men aged 18-45 years reported having had a diagnosis of genital warts. The results provide baseline information for developing and monitoring prevention strategies against genital warts, such as vaccination against human papillomavirus types 6 and 11.

The quantitative measurement of consciousness during epileptic seizures.

PubMed

Nani, Andrea; Cavanna, Andrea E

2014-01-01

The assessment of consciousness is a fundamental element in the classification of epileptic seizures. It is, therefore, of great importance for clinical practice to develop instruments that enable an accurate and reliable measurement of the alteration of consciousness during seizures. Over the last few years, three psychometric scales have been specifically proposed to measure ictal consciousness: the Ictal Consciousness Inventory (ICI), the Consciousness Seizure Scale (CSS), and the Responsiveness in Epilepsy Scale--versions I and II (RES-I and RES-II). The ICI is a self-report psychometric instrument which retrospectively assesses ictal consciousness along the dimensions of the level/arousal and contents/awareness. The CSS has been used by clinicians to quantify the impairment of consciousness in order to establish correlations with the brain mechanisms underlying alterations of consciousness during temporal lobe seizures. The most recently developed observer-rated instrument is the RES-I, which has been used to assess responsiveness during epileptic seizures in patients undergoing video-EEG. The implementation of standardized psychometric tools for the assessment of ictal consciousness can complement clinical observations and contribute to improve accuracy in seizure classification. © 2013.

Iraqi Kurdistan region is one of the areas where female genital mutilation is reportedly widely practiced but inadequately studied. The aim of this study was to determine (i) the prevalence of female genital mutilation among Muslim Kurdish women in Erbil city, (ii) the patterns and types of female genital mutilation, (iii) the factors associated with this practice and (iv) women's knowledge and attitudes towards this practice. A cross-sectional study was conducted in the primary health care centers and the Maternity Teaching Hospital in Erbil city, involving 1987 women aged 15-49 years. Data were obtained about female genital mutilation status and knowledge and perception towards this practice. The participants were clinically examined to verify the self-reported female genital mutilation status. The self-reported prevalence of female genital mutilation was 70.3%, while it was 58.6% according to clinical examination of the women's genitalia. The most common type of female genital mutilation was type I (99.6%) and the most common age at which mutilation was performed was 4-7 years (60.2%). This practice was mostly performed by traditional birth attendants (72.5%). Only 6.4% of mutilated women reported having complications after mutilation, most commonly bleeding (3.6%). The practice was more reported among housewives (OR = 3.3), those women whose mothers were mutilated (OR = 15.1) or with unknown mutilation status (OR = 7.3) and those women whose fathers were illiterate (OR = 1.4) or could only read and write (OR = 1.6). The common reasons for practicing female genital mutilation were cultural tradition (46.7%) and dictate of religion (38.9%). Only 30% of the participants were aware about the health consequences of female genital mutilation. More than one third (36.6%) of the women support the practice and 34.5% have intention to mutilate their daughters.

See Schiff (doi:10.1093/awx209) for a scientific commentary on this article. Patients with acute severe traumatic brain injury may recover consciousness before self-expression. Without behavioural evidence of consciousness at the bedside, clinicians may render an inaccurate prognosis, increasing the likelihood of withholding life-sustaining therapies or denying rehabilitative services. Task-based functional magnetic resonance imaging and electroencephalography techniques have revealed covert consciousness in the chronic setting, but these techniques have not been tested in the intensive care unit. We prospectively enrolled 16 patients admitted to the intensive care unit for acute severe traumatic brain injury to test two hypotheses: (i) in patients who lack behavioural evidence of language expression and comprehension, functional magnetic resonance imaging and electroencephalography detect command-following during a motor imagery task (i.e. cognitive motor dissociation) and association cortex responses during language and music stimuli (i.e. higher-order cortex motor dissociation); and (ii) early responses to these paradigms are associated with better 6-month outcomes on the Glasgow Outcome Scale-Extended. Patients underwent functional magnetic resonance imaging on post-injury Day 9.2 ± 5.0 and electroencephalography on Day 9.8 ± 4.6. At the time of imaging, behavioural evaluation with the Coma Recovery Scale-Revised indicated coma (n = 2), vegetative state (n = 3), minimally conscious state without language (n = 3), minimally conscious state with language (n = 4) or post-traumatic confusional state (n = 4). Cognitive motor dissociation was identified in four patients, including three whose behavioural diagnosis suggested a vegetative state. Higher-order cortex motor dissociation was identified in two additional patients. Complete absence of responses to language, music and motor imagery was only observed in coma patients.

The Emergence of Primary Anoetic Consciousness in Episodic Memory

PubMed Central

Vandekerckhove, Marie; Bulnes, Luis Carlo; Panksepp, Jaak

2014-01-01

Based on an interdisciplinary perspective, we discuss how primary-process, anoetic forms of consciousness emerge into higher forms of awareness such as knowledge-based episodic knowing and self-aware forms of higher-order consciousness like autonoetic awareness. Anoetic consciousness is defined as the rudimentary state of affective, homeostatic, and sensory-perceptual mental experiences. It can be considered as the autonomic flow of primary-process phenomenal experiences that reflects a fundamental form of first-person “self-experience,” a vastly underestimated primary form of phenomenal consciousness. We argue that this anoetic form of evolutionarily refined consciousness constitutes a critical antecedent that is foundational for all forms of knowledge acquisition via learning and memory, giving rise to a knowledge-based, or noetic, consciousness as well as higher forms of “awareness” or “knowing consciousness” that permits “time-travel” in the brain-mind. We summarize the conceptual advantages of such a multi-tiered neuroevolutionary approach to psychological issues, namely from genetically controlled primary (affective) and secondary (learning and memory), to higher tertiary (developmentally emergent) brain-mind processes, along with suggestions about how affective experiences become more cognitive and object-oriented, allowing the developmental creation of more subtle higher mental processes such as episodic memory which allows the possibility of autonoetic consciousness, namely looking forward and backward at one’s life and its possibilities within the “mind’s eye.” PMID:24427125

To describe the practices and care with the genital area of female college students. A descriptive analytical study evaluated the habits and traditions of 364 students from the University of Campinas (Unicamp) regarding the use of underwear, body piercings, tattoos, hair removal and sexual practices. A questionnaire with 42 questions assessed the most current practices among female college students. All questions were self answered and the questionnaires, without any identification, were placed in sealed ballot boxes to ensure the confidentiality of information. The responses were tabulated in Microsoft® Excel 2007 to obtain univariate analysis. The mean age of the college students in the study was 21 years (SD ± 2.7), and 84% were white. The volunteers who participated in this study were from the biological science area (50%), the exact science area (29%) or the humanity area (21%). It was observed that 61.8% of the respondents wear cotton panties, but at the same time 75.4% wear tight jeans, and only 18.4% wore no panties when sleeping. Only one participant reported having had genital piercing and none of them reported tattooing. Most female college students do genital waxing, and approximately 1/3 of them do so completely. After hair removal, 2/3 apply an anti-inflammatory and/or moisturizer to the region. Only 62% use condoms and 17.6% use a lubricant during intercourse. Half of them receive oral sex, 17.9% practice anal sex and 26.6% of them report feeling pain during sexual intercourse. Vaginal discharge after intercourse was reported in 25.6% of the cases. Young female college students from Brazilian public universities have many inadequate care habits related to their genital area. They do not use genital piercing and tattoos, but report having pain during sexual intercourse and vaginal discharge after sex in a large number of cases.

Psychogenic amnesia--a malady of the constricted self.

Staniloiu, Angelica; Markowitsch, Hans J; Brand, Matthias

2010-09-01

Autobiographical-episodic memory is the conjunction of subjective time, autonoetic consciousness and the experiencing self. Understanding the neural correlates of autobiographical-episodic memory might therefore be essential for shedding light on the neurobiology underlying the experience of being an autonoetic self. In this contribution we illustrate the intimate relationship between autobiographical-episodic memory and self by reviewing the clinical and neuropsychological features and brain functional imaging correlates of psychogenic amnesia - a condition that is usually characterized by severely impaired retrograde memory functioning, in absence of structural brain damage as detected by standard imaging. We demonstrate that in this disorder the autobiographical-episodic memory deficits do not exist in isolation, but occur with impairments of the autonoetic self-consciousness, emotional processing, and theory of mind or executive functions. Furthermore functional and metabolic brain alterations involving regions that are agreed upon to exert crucial roles in memory processes were frequently found to accompany the psychogenic memory "loss".

Computational consciousness: building a self-preserving organism.

PubMed

Barros, Allan Kardec

2010-01-01

Consciousness has been a subject of crescent interest among the neuroscience community. However, building machine models of it is quite challenging, as it involves many characteristics and properties of the human brain which are poorly defined or are very abstract. Here I propose to use information theory (IT) to give a mathematical framework to understand consciousness. For this reason, I used the term "computational". This work is grounded on some recent results on the use of IT to understand how the cortex codes information, where redundancy reduction plays a fundamental role. Basically, I propose a system, here called "organism", whose strategy is to extract the maximal amount of information from the environment in order to survive. To highlight the proposed framework, I show a simple organism composed of a single neuron which adapts itself to the outside dynamics by taking into account its internal state, whose perception is understood here to be related to "feelings".

What is consciousness, and could machines have it?

PubMed

Dehaene, Stanislas; Lau, Hakwan; Kouider, Sid

2017-10-27

The controversial question of whether machines may ever be conscious must be based on a careful consideration of how consciousness arises in the only physical system that undoubtedly possesses it: the human brain. We suggest that the word "consciousness" conflates two different types of information-processing computations in the brain: the selection of information for global broadcasting, thus making it flexibly available for computation and report (C1, consciousness in the first sense), and the self-monitoring of those computations, leading to a subjective sense of certainty or error (C2, consciousness in the second sense). We argue that despite their recent successes, current machines are still mostly implementing computations that reflect unconscious processing (C0) in the human brain. We review the psychological and neural science of unconscious (C0) and conscious computations (C1 and C2) and outline how they may inspire novel machine architectures.

In order to better understand the functional contribution of resting state activity to conscious cognition, we aimed to review increases and decreases in functional magnetic resonance imaging (fMRI) functional connectivity under physiological (sleep), pharmacological (anesthesia), and pathological altered states of consciousness, such as brain death, coma, vegetative state/unresponsive wakefulness syndrome, and minimally conscious state. The reviewed resting state networks were the DMN, left and right executive control, salience, sensorimotor, auditory, and visual networks. We highlight some methodological issues concerning resting state analyses in severely injured brains mainly in terms of hypothesis-driven seed-based correlation analysis and data-driven independent components analysis approaches. Finally, we attempt to contextualize our discussion within theoretical frameworks of conscious processes. We think that this “lesion” approach allows us to better determine the necessary conditions under which normal conscious cognition takes place. At the clinical level, we acknowledge the technical merits of the resting state paradigm. Indeed, fast and easy acquisitions are preferable to activation paradigms in clinical populations. Finally, we emphasize the need to validate the diagnostic and prognostic value of fMRI resting state measurements in non-communicating brain damaged patients. PMID:22969735

Gender differences in self-conscious emotional experience: a meta-analysis.

PubMed

Else-Quest, Nicole M; Higgins, Ashley; Allison, Carlie; Morton, Lindsay C

2012-09-01

The self-conscious emotions (SCE) of guilt, shame, pride, and embarrassment are moral emotions, which motivate adherence to social norms and personal standards and emerge in early childhood following the development of self-awareness. Gender stereotypes of emotion maintain that women experience more guilt, shame, and embarrassment but that men experience more pride. To estimate the magnitude of gender differences in SCE experience and to determine the circumstances under which these gender differences vary, we meta-analyzed 697 effect sizes representing 236,304 individual ratings of SCE states and traits from 382 journal articles, dissertations, and unpublished data sets. Guilt (d = -0.27) and shame (d = -0.29) displayed small gender differences, whereas embarrassment (d = -0.08), authentic pride (d = -0.01), and hubristic pride (d = 0.09) showed gender similarities. Similar to previous findings of ethnic variations in gender differences in other psychological variables, gender differences in shame and guilt were significant only for White samples or samples with unspecified ethnicity. We found larger gender gaps in shame with trait (vs. state) scales, and in guilt and shame with situation- and scenario-based (vs. adjective- and statement-based) items, consistent with predictions that such scales and items tend to tap into global, nonspecific assessments of the self and thus reflect self-stereotyping and gender role assimilative effects. Gender differences in SCE about domains such as the body, sex, and food or eating tended to be larger than gender differences in SCE about other domains. These findings contribute to the literature demonstrating that blanket stereotypes about women's greater emotionality are inaccurate. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

'What' do we call consciousness? 'When' and 'Where' in the brain do conscious states occur, and 'How' conscious processing and conscious access to a given content work? In the present paper, we present a non-exhaustive overview of each of these 4 major issues, we provide the reader with a brief description of the major difficulties related to these issues, we highlight the current theoretical points of debate, and we advocate for the explanatory power of the "global workspace" model of consciousness (Baars 1989; Dehaene and Naccache 2001; Dehaene, Changeux et al. 2006) which can accommodate for a fairly large proportion of current experimental findings, and which can be used to reinterpret apparent contradictory findings within a single theoretical framework. Most notably, we emphasize the crucial importance to distinguish genuine neural signatures of conscious access from neural events correlated with consciousness but occurring either before ('upstream') or after ('downstream').

Human papillomavirus (HPV) causes two types of external genital lesions (EGLs) in men: genital warts (condyloma) and penile intraepithelial neoplasia (PeIN). The purpose of this study was to describe genital HPV progression to a histopathologically confirmed HPV-related EGL. A prospective analysis nested within the HPV Infection in Men (HIM) study was conducted among 3033 men. At each visit, visually distinct EGLs were biopsied; the biopsy specimens were subjected to pathologic evaluation and categorized by pathologic diagnoses. Genital swabs and biopsies were used to identify HPV types using the Linear Array genotyping method for swabs and INNO-LiPA for biopsy specimens. EGL incidence was determined among 1788 HPV-positive men, and cumulative incidence rates at 6, 12, and 24 mo were estimated. The proportion of HPV infections that progressed to EGL was also calculated, along with median time to EGL development. Among 1788 HPV-positive men, 92 developed an incident EGL during follow-up (9 PeIN and 86 condyloma). During the first 12 mo of follow-up, 16% of men with a genital HPV 6 infection developed an HPV 6-positive condyloma, and 22% of genital HPV 11 infections progressed to an HPV 11-positive condyloma. During the first 12 mo of follow-up, 0.5% of men with a genital HPV 16 infection developed an HPV 16-positive PeIN. Although we expected PeIN to be a rare event, the sample size for PeIN (n=10) limited the types of analyses that could be performed. Most EGLs develop following infection with HPV 6, 11, or 16, all of which could be prevented with the 4-valent HPV vaccine. In this study, we looked at genital human papillomavirus (HPV) infections that can cause lesions in men. The HPV that we detected within the lesions could be prevented by a vaccine.

Schistosoma (S.) haematobium is a neglected tropical disease which may affect any part of the genital tract in women. Female genital schistosomiasis (FGS) may cause abnormal vaginal discharge, contact bleeding, genital tumours, ectopic pregnancies and increased susceptibility to HIV. Symptoms may mimic those typical of sexually transmitted infections (STIs) and women with genital schistosomiasis may be incorrectly diagnosed. An expert consensus meeting suggested that the following findings by visual inspection should serve as proxy indicators for the diagnosis of schistosomiasis of the lower genital tract in women from S. haematobium endemic areas: sandy patches appearing as (1) single or clustered grains or (2) sandy patches appearing as homogenous, yellow areas, or (3) rubbery papules. In this atlas we aim to provide an overview of the genital mucosal manifestations of schistosomiasis in women. Photocolposcopic images were captured from women, between 1994 and 2012 in four different study sites endemic for S. haematobium in Malawi, Zimbabwe, South Africa and Madagascar. Images and specimens were sampled from sexually active women between 15 and 49 years of age. Colposcopic images of other diseases are included for differential diagnostic purposes. This is the first atlas to present the clinical manifestations of schistosomiasis in the lower female genital tract. It will be freely available for online use, downloadable as a presentation and for print. It could be used for training purposes, further research, and in clinical practice.

In women, anorectal infections with Chlamydia trachomatis (CT) are about as common as genital CT, yet the anorectal site remains largely untested in routine care. Anorectal CT frequently co-occurs with genital CT and may thus often be treated co-incidentally. Nevertheless, post-treatment detection of CT at both anatomic sites has been demonstrated. It is unknown whether anorectal CT may play a role in post-treatment transmission. This study, called FemCure, in women who receive routine treatment (either azithromycin or doxycycline) aims to understand the post-treatment transmission of anorectal CT infections, i.e., from their male sexual partner(s) and from and to the genital region of the same woman. The secondary objective is to evaluate other reasons for CT detection by nucleic acid amplification techniques (NAAT) such as treatment failure, in order to inform guidelines to optimize CT control. A multicentre prospective cohort study (FemCure) is set up in which genital and/or anorectal CT positive women (n = 400) will be recruited at three large Dutch STI clinics located in South Limburg, Amsterdam and Rotterdam. The women self-collect anorectal and vaginal swabs before treatment, and at the end of weeks 1, 2, 4, 6, 8, 10, and 12. Samples are tested for presence of CT-DNA (by NAAT), load (by quantitative polymerase chain reaction -PCR), viability (by culture and viability PCR) and CT type (by multilocus sequence typing). Sexual exposure is assessed by online self-administered questionnaires and by testing samples for Y chromosomal DNA. Using logistic regression models, the impact of two key factors (i.e., sexual exposure and alternate anatomic site of infection) on detection of anorectal and genital CT will be assessed. The FemCure study will provide insight in the role of anorectal chlamydia infection in maintaining the CT burden in the context of treatment, and it will provide practical recommendations to reduce avoidable transmission.

2017-01-01

The morbidity and mortality due to tuberculosis (TB) is high worldwide, and the burden of disease among women is significant, especially in developing countries. Mycobacterium tuberculosis bacilli reach the genital tract primarily by haematogenous spread and dissemination from foci outside the genitalia with lungs as the common primary focus. Genital TB in females is a chronic disease with low-grade symptoms. The fallopian tubes are affected in almost all cases of genital TB, and along with endometrial involvement, it causes infertility in patients. Many women present with atypical symptoms which mimic other gynaecological conditions. A combination of investigations is needed to establish the diagnosis of female genital TB (FGTB). Multidrug anti-TB treatment is the mainstay of management and surgery may be required in advanced cases. Conception rates are low among infertile women with genital TB even after multidrug therapy for TB, and the risk of complications such as ectopic pregnancy and miscarriage is high. More research is needed on the changing trends in the prevalence and on the appropriate methods for diagnosis of FGTB. PMID:28862174

Genital Warts

2012-01-01

External genital warts, also known as condylomata acuminata, are extremely common, with between 500,000 to one million new cases diagnosed each year in the United States alone. To date, more than 120 distinct subtypes of human papillomavirus have been identified. Human papillomavirus types 6 and 11 rarely give rise to cervical cancers, but are responsible for 90 percent of the cases of genital warts. The current treatment options are largely centered upon removal of the warts rather than elimination of the underlying viral infection. A wide range of therapies are presently in use, which are highly variable and can differ dramatically with respect to cost, side-effect profiles, dosing schedules, duration of treatment, and overall effectiveness. As of yet, no definitive therapy has emerged as the ideal standard of care in the treatment of genital warts, and therapy selection generally occurs in a patient-specific manner. PMID:22768354

Understanding how the human brain translates sensory impressions into conscious percepts is a key challenge of neuroscience research. Work in this area has overwhelmingly centered on the conscious experience of vision at the exclusion of the other senses—in particular, smell. We hypothesized that the orbitofrontal cortex (OFC) is a central substrate for olfactory conscious experience because of its privileged physiological role in odor processing. Combining functional magnetic resonance imaging, peripheral autonomic recordings, and olfactory psychophysics, we studied a case of complete anosmia (smell loss) in a patient with circumscribed traumatic brain injury to the right OFC. Despite a complete absence of conscious olfaction, the patient exhibited robust “blind smell,” as indexed by reliable odor-evoked neural activity in the left OFC and normal autonomic responses to odor hedonics during presentation of stimuli to the left nostril. These data highlight the right OFC’s critical role in subserving human olfactory consciousness. PMID:20817780

Warts (genital)

2007-01-01

Introduction External genital warts (EGWs) are sexually transmitted benign epidermal growths caused by the human papillomavirus (HPV), on the anogenital areas of both females and males. About 50-60% of sexually active women aged 18-49 have been exposed to HPV infection, but only 10-15% will have genital warts. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for external genital warts? What are the effects of interventions to prevent transmission of external genital warts? We searched: Medline, Embase, The Cochrane Library and other important databases up to February 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 47 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: bi- and trichloroacetic acid; condoms; cryotherapy; electrosurgery; imiquimod; intralesional, topical, or systemic interferons; laser surgery; podophyllin; podophyllotoxin; surgical excision; and vaccines.

Consciousness: Its Neurobiology and the Major Classes of Impairment

PubMed Central

Goldfine, Andrew M.; Schiff, Nicholas D.

2011-01-01

Summary Normal human consciousness requires brainstem, basal forebrain, and diencephalic areas to support generalized arousal, as well as functioning thalamocortical networks to become aware of, and respond to environmental and internal stimuli. Injury to or disconnection of these interconnected systems, typically from cardiac arrest and traumatic brain injury, can result in disorders of consciousness, including coma, vegetative state, minimally conscious state, and akinetic mutism. Similar brain injuries can also result in loss of motor output out of proportion to consciousness, resulting in misdiagnoses of disorders of consciousness. We review pathology and imaging studies and derive mechanistic models for each of these conditions, to aid in the assessment and prognosis of individual patients. We further suggest how such models may guide the development of target-based treatment algorithms to enhance recovery of consciousness in many of these patient. PMID:22032656

Background Schistosoma (S.) haematobium is a neglected tropical disease which may affect any part of the genital tract in women. Female genital schistosomiasis (FGS) may cause abnormal vaginal discharge, contact bleeding, genital tumours, ectopic pregnancies and increased susceptibility to HIV. Symptoms may mimic those typical of sexually transmitted infections (STIs) and women with genital schistosomiasis may be incorrectly diagnosed. An expert consensus meeting suggested that the following findings by visual inspection should serve as proxy indicators for the diagnosis of schistosomiasis of the lower genital tract in women from S. haematobium endemic areas: sandy patches appearing as (1) single or clustered grains or (2) sandy patches appearing as homogenous, yellow areas, or (3) rubbery papules. In this atlas we aim to provide an overview of the genital mucosal manifestations of schistosomiasis in women. Methodology/Principal findings Photocolposcopic images were captured from women, between 1994 and 2012 in four different study sites endemic for S. haematobium in Malawi, Zimbabwe, South Africa and Madagascar. Images and specimens were sampled from sexually active women between 15 and 49 years of age. Colposcopic images of other diseases are included for differential diagnostic purposes. Significance This is the first atlas to present the clinical manifestations of schistosomiasis in the lower female genital tract. It will be freely available for online use, downloadable as a presentation and for print. It could be used for training purposes, further research, and in clinical practice. PMID:25412334

Genital morphology (especially male) among the animal kingdom is characterized by extensive differences that even members of closely related species with similar general morphology may have remarkably diverse genitalia. To present the sexual medicine specialist with a basic understanding of the current hypotheses on genital evolution with an emphasis on the sexual selection theories. A review of current literature on the theories of genital evolution. Analysis of the supporting evidence for the sexual selection theories of genital evolution. Several theories have been proposed to explain genital evolution. Currently, the sexual selection theories are being considered to present valid and solid evidence explaining genital evolution. However, other theories, including sexual conflict, are still being investigated. All theories of genital evolution have their own weaknesses and strengths. Given that many complex biological mechanisms, mostly unknown yet, are involved in the process of genital evolution, it is thus reasonable to conclude that not one theory can independently explain genital evolution. It is likely that these mechanisms may prove to have synergistic rather than exclusive effects.

Self-conscious emotions׳ role in functional outcomes within clinical populations.

PubMed

Macaulay, Rebecca; Cohen, Alex

2014-04-30

Patients with severe mental illnesses (SMI) often experience dysfunction in their ability to efficiently carry out everyday roles and/or skills. These deficits are seen across many domains of daily functioning. We suggest that the "self-conscious emotions" of pride and shame play a role in these functional outcomes. Pride and shame appear to facilitate individuals׳ ability to evaluate their group status, detect social threats, and to adjust their behaviors accordingly. This study utilized an objective performance measure of functional capacity and a self-report of quality of life (QoL) to examine the respective roles of pride and shame in functional outcomes within two SMI patient groups (schizophrenia and affective disorder) and a community control group. The influence of neurocognition, affect and symptomatology on functional outcomes was also assessed. The patient groups did not differ in cognitive functioning, QoL, or shame. The schizophrenia group reported significantly higher pride and displayed worse objective performance than the other groups. Within each of the groups, shame had an inverse relationship with QoL, while pride positively associated with QoL. Shame associated with worse functional capacity in the schizophrenia group. Shame associated with better functional capacity, while pride associated with worse functional capacity within the affective disorder group. Copyright © 2014 Elsevier Ireland Ltd.

The science of consciousness - Basics, models, and visions.

PubMed

Hinterberger, Thilo

2015-12-01

This article presents a few models and aspects of the phenomenon consciousness that are emerging from modern neuroscience and might serve as a basis for scientific discourse in the field of Applied Consciousness Sciences. A first model describes the dynamics of information processing in the brain. The evoked electric brain potentials represent a hierarchical sequence of functions playing an important role in conscious perception. These range from primary processing, attention, pattern recognition, categorization, associations to judgments, and complex thoughts. Most functions seem to be implemented in the brain's neural network operating as a neurobiological computer. Another model treats conscious perception as a process of internalisation leading to the "self" as conscious observer. As a consequence, every conscious perception can be seen as a reduced and already interpreted observation of an inner representation of an outer or imagined "world." Subjective experience thus offers properties which can only be experienced from the inside and cannot be made objective. Basic values of humanity such as responsibility, love, compassion, freedom, and dignity can be derived from these subjective qualities. Therefore, in contrast to the Natural Sciences, the Science of Consciousness additionally is challenged to deal with those subjective qualities, emphasizing the resulting influence on health, social interactions, and the whole society.

The enhanced self-heterodyne synthetic aperture imaging ladar (SAIL) self-heterodynes two polarization-orthogonal echo signals to eliminate the phase disturbance caused by atmospheric turbulence and mechanical trembling, uses heterodyne receiver instead of self-heterodyne receiver to improve signal-to-noise ratio. The principle and structure of the enhanced self-heterodyne SAIL are presented. The imaging process of enhanced self-heterodyne SAIL for distributed target is also analyzed. In enhanced self-heterodyne SAIL, the phases of two orthogonal-polarization beams are modulated by four cylindrical lenses in transmitter to improve resolutions in orthogonal direction and travel direction, which will generate ghost image. The generation process of ghost image in enhanced self-heterodyne SAIL is mathematically detailed, and a method of eliminating ghost image is also presented, which is significant for far-distance imaging. A number of experiments of enhanced self-heterodyne SAIL for distributed target are presented, these experimental results verify the theoretical analysis of enhanced self-heterodyne SAIL. The enhanced self-heterodyne SAIL has the capability to eliminate the influence from the atmospheric turbulence and mechanical trembling, has high advantage in detecting weak signals, and has promising application for far-distance ladar imaging.

Background: Perceived body image is an important potential predictor of nutritional status. Body image misconception during adolescence is unexplored field in Indian girls. Objectives: To study the consciousness of adolescent girls about their body image. Materials and Methods: This multistage observational study was conducted on 586 adolescent girls of age 10–19 years in Lucknow district (151 from rural, 150 from slum, and 286 from urban area) of Uttar Pradesh, India. Information on desired and actual body size was collected with the help of predesigned questionnaire. Results: 20.5% of studied girls show aspiration to become thin, who already perceived their body image as too thin. 73.4% adolescent girls were satisfied with their body image, while 26.6% were dissatisfied. The dissatisfaction was higher among girls of urban (30.2%) and slum (40.0%) areas in comparison to rural (22.5%) area. Percentage of satisfied girls was less in the 13–15 years (69.9%) age groups in comparison to 10–12 years (76.5%) and 16–19 years (76.4%). Among girls satisfied with their body image, 32.8% girls were found underweight, and 38.4% were stunted. Underweight girls (42.1%) and stunted girls (64.9%) were higher in number within satisfied girls of slum area. Among all of these adolescent girls, 32.8% of girls had overestimated their weight, while only 4.9% of girls had underestimated their weight. Conclusions: This study concludes that desire to become thin is higher in adolescent girls, even in those who already perceived their body image as too thin. PMID:22090673

Blind subjects construct conscious mental images of visual scenes encoded in musical form.

Blind (previously sighted) subjects are able to analyse, describe and graphically represent a number of high-contrast visual images translated into musical form de novo. We presented musical transforms of a random assortment of photographic images of objects and urban scenes to such subjects, a few of which depicted architectural and other landmarks that may be useful in navigating a route to a particular destination. Our blind subjects were able to use the sound representation to construct a conscious mental image that was revealed by their ability to depict a visual target by drawing it. We noted the similarity between the way the visual system integrates information from successive fixations to form a representation that is stable across eye movements and the way a succession of image frames (encoded in sound) which depict different portions of the image are integrated to form a seamless mental image. Finally, we discuss the profound resemblance between the way a professional musician carries out a structural analysis of a musical composition in order to relate its structure to the perception of musical form and the strategies used by our blind subjects in isolating structural features that collectively reveal the identity of visual form.

Clinical and subclinical genital herpes simplex virus type 2 (HSV-2) reactivations have been associated with increases in human immunodeficiency virus (HIV)-1 genital shedding. Whether HSV-2 shedding contributes to the selection of specific genital HIV-1 variants remains unknown. We evaluated the genetic diversity of genital and blood HIV-1 RNA and DNA in 14 HIV-1/HSV-2-co-infected women, including seven with HSV-2 genital reactivation, and seven without as controls. HIV-1 DNA and HIV-1 RNA env V1-V3 sequences in paired blood and genital samples were compared. The HSV-2 selection pressure on HIV was estimated according to the number of synonymous substitutions (dS), the number of non-synonymous substitutions (dN) and the dS/dN ratio within HIV quasi-species. HIV-1 RNA levels in cervicovaginal secretions were higher in women with HSV-2 replication than in controls (p0.02). Plasma HIV-1 RNA and genital HIV-1 RNA and DNA were genetically compartmentalized. No differences in dS, dN and the dS/dN ratio were observed between the study groups for either genital HIV-1 RNA or plasma HIV-1 RNA. In contrast, dS and dN in genital HIV-1 DNA were significantly higher in patients with HSV-2 genital reactivation (p <0.01 and p <0.05, respectively). The mean of the dS/dN ratio in genital HIV-1 DNA was slightly higher in patients with HSV-2 genital replication, indicating a trend for purifying selection (p 0.056). HSV-2 increased the genetic diversity of genital HIV-1 DNA. These observations confirm molecular interactions between HSV-2 and HIV-1 at the genital tract level.

Genital herpes.

PubMed

Garland, Suzanne M; Steben, Marc

2014-10-01

Genital herpes is a relatively common infection caused by herpes simplex virus (HSV) type one or two (HSV-1, HSV-2) respectively. It is acquired most commonly via sexual activity. More recently there has been an increase in infections due to HSV-1. Most new cases of genital HSV are not diagnosed due to HSV infections having short-lived signs and symptoms, or in many instances are asymptomatic. Hence many people infected with HSV are unaware that they have it. The risk of transmission to a partner is highest during outbreak periods, when there are visible lesions, although genital HSV can also be transmitted during asymptomatic periods. Use of condoms and antiviral medications assist in preventing transmission. Antiviral agents are effective in controlling clinical episodes, but do not eradicate infection, which remains latent for the life of a patient. Despite the surge in vaccine research, there is unfortunately no readily available preventative or therapeutic vaccine for HSV to date. Crown Copyright © 2014. Published by Elsevier Ltd.

Female genital mutilation in Britain.

PubMed

Black, J A; Debelle, G D

1995-06-17

The practice of female genital mutilation predates the founding of both Christianity and Islam. Though largely confined among Muslims, the operation is also practiced in some Christian communities in Africa such that female genital mutilation takes place in various forms in more than twenty African countries, Oman, Yemen, the United Arab Emirates, and by some Muslims in Malaysia and Indonesia. In recent decades, ethnic groups which practice female genital mutilation have immigrated to Britain. The main groups are from Eritrea, Ethiopia, Somalia, and Yemen. In their own countries, an estimated 80% of women have had the operation. Female genital mutilation has been illegal in Britain since 1985, but it is practiced illegally or children are sent abroad to undergo the operation typically at age 7-9 years. It is a form of child abuse which poses special problems. The authors review the history of female genital mutilation and describe its medical complications. Assuming that the size of the population in Britain of ethnic groups which practice or favor female genital mutilation remains more or less unchanged, adaptation and acculturation will probably cause the practice to die out within a few generations. Meanwhile, there is much to be done. A conspiracy of silence exists in medical circles as well as widespread ignorance. Moreover, none of a number of well-known obstetric and pediatric textbooks mentions female genital mutilation, while the National Society for the Prevention of Cruelty to Children has neither information nor instructional material. It is high time that the problem was more widely and openly discussed.

Ano-Genital Warts (AGW) like other Sexually Transmitted Diseases (STD) is associated with Human Immunodeficiency Virus (HIV) infection. This study of AGW was done in HIV positive and HIV negative patients. To study the risk factors and clinical presentations of ano-genital warts in HIV positive and negative patients. A comparative, cross-sectional, descriptive study of 25 HIV positive and 25 HIV negative (n=50) AGW patients between 15-60 years of both sex was conducted in Dr. D. Y. Patil Hospital and Research Centre from July 2014 to July 2016. Significant association of HIV positivity (p<0.05) was observed between age group of 15-30 years and HIV negative status (p<0.05) in age group of 31-45 years. HIV positive status significantly higher in patients with self-admitted multiple sexual partners (p<0.01), homosexuality (p<0.05) and presentation with anal warts (p<0.01). HIV negative status correlated significantly with single sexual partner admission (p<0.01) and hetero-sexuality (p<0.05). Gender did not show significant association with number of sexual partners or HIV positivity. Extra-genital or only genital warts had no association with HIV status. Co-STDs though more in number in ser-positive group, did not show any significant association with HIV positivity (p>0.05). No patient presented with changes of malignancy. Four were adolescents below 19 years. Two patients had atypical presentations of giant condylomata i.e., Buschke-Lowenstein Tumour (BLT). HIV positivity was significantly associated with the risk factors of age below 30 years, homo sexuality and multiple sexual partners. Anal warts were significantly common in HIV positive patients. Four adolescents with AGW underline the need for high risk behaviour counselling. No patient had malignant ano-genital warts. Follow up of these patients with Human Papilloma Virus (HPV) sub-typing is necessary.

Images portraying exercise are commonly used to promote exercise behavior and to measure automatic associations of exercise (e.g., via implicit association tests). The effectiveness of these promotion efforts and the validity of measurement techniques partially rely on the untested assumption that the images being used are perceived by the general public as portrayals of exercise that is pleasant and motivating. The aim of this study was to investigate how content of images impacted people's automatic and reflective evaluations of exercise images. Participants (N = 90) completed a response time categorization task (similar to the implicit association test) to capture how automatically people perceived each image as relevant to Exercise or Not exercise. Participants also self-reported their evaluations of the images using visual analog scales with the anchors: Exercise/Not exercise, Does not motivate me to exercise/Motivates me to exercise, Pleasant/Unpleasant, and Energizing/Deactivating. People tended to more strongly automatically associate images with exercise if the images were of an outdoor setting, presented sport (as opposed to active labor or gym-based) activities, and included young (as opposed to middle-aged) adults. People tended to reflectively find images of young adults more motivating and relevant to exercise than images of older adults. The content of exercise images is an often overlooked source of systematic variability that may impact measurement validity and intervention effectiveness. PMID:29375419

The genital herpes problem in pregnancy.

PubMed

Guerra, B; Puccetti, C; Cervi, F

2012-10-01

Genital herpes is a common sexually transmitted infection. In reproductive age it involves the additional risk of vertical transmission to the neonate. Rates of transmission are affected by the viral type and whether the infection around delivery is primary or recurrent. Neonatal herpes is a rare but very severe complication of genital herpes infection and is caused by contact with infected genital secretions at the time of labor. Maternal acquisition of herpes simplex virus (HSV) in the third trimester of pregnancy carries the highest risk of neonatal transmission. Prevention of neonatal herpes depends on preventing acquisition of genital HSV infection during late pregnancy and avoiding exposure of the infant to herpetic lesions during delivery. Uninfected woman should be counselled about the need of avoiding sexual contact during the third trimester. Elective caesarean section before the onset of labor is the choice mode of delivery for women with genital lesions or with prodromal symptoms near the term, even if it offers only a partial protection against neonatal infection. Antiviral suppressive therapy is used from 36 weeks of gestation until delivery in pregnant women with recurrences to prevent genital lesions at the time of labor so reducing the need of caesarean sections. Currently, routine maternal serologic screening is not yet recommended. Because most mothers of infants who acquire neonatal herpes lack histories of clinically evident genital herpes, researchers should focus on the recognition of asymptomatic primary genital HSV infections.

Examining the time course of genital and subjective sexual responses in women and men with concurrent plethysmography and thermography.

Sexual response is a dynamic process, though there is limited knowledge of the time course and relationships among its psychological and physiological components. To address this gap, we concurrently assessed self-reported sexual arousal, genital temperature (with thermography), and genital vasocongestion (with vaginal photoplethysmography [VPP] or penile plethysmography [PPG]) during sexual and nonsexual films in 28 androphilic women (attracted to men) and 27 gynephilic men (attracted to women). Men and women had similarly strong agreement between subjective and genital responses (sexual concordance) with thermography, but this agreement was stronger in men than women with PPG/VPP. The time course of changes in self-reported arousal was most similar to changes in genital temperature (i.e., time to onset and peak response). Time-lagged correlations and multilevel modeling revealed changes in the strength of relationships between aspects of sexual response over time. Results highlight the dynamic nature of sexual response and drawbacks of relying on zero-order correlations to characterize sexual concordance. Copyright © 2017 Elsevier B.V. All rights reserved.

As he was very motivated to take pictures of him while being operated upon, the authors adapted conscious sedation technique with variable depth according to Ramsey's scale, in order to revert to awake state to perform the intended neurosurgical procedure. The patient tolerated the situation satisfactorily and was cooperative till the finish, without any event. We elicit in this report the special environment of iMRI OT for lengthy operation in pinned fixed patient having craniotomy. PMID:25885085

[Differences in sentence completion test responses based on degree of self-disclosure].

PubMed

Kumano, Michiko

2006-10-01

Projective tests are considered to uncover unconscious emotions while avoiding psychological resistance. However, the results of projective tests may be affected by conscious emotions. This study investigates whether self-disclosure, which is a conscious factor, affected the results of a sentence completion test (SCT), which is a projective test. Eighty-five university students completed a questionnaire about their degree of self-disclosure, and a SCT. The results showed that low disclosers gave more negative responses on the SCT (such as denial responses, physiologically related responses, short responses, and short emotional responses) than high disclosers. High disclosers expressed more emotions, thoughts and feelings (i.e., opinions, positive emotions, wishes, directive disclosure responses, and positive self-images) than low disclosers. Although projective tests are assumed to minimize psychological resistance, the low disclosers gave more defensive responses on the SCT, and the high disclosers exhibited more emotional responses. In summary, self-disclosure, which is a conscious factor, affected SCT responses.

Consciousness is a multifaceted concept; its different aspects vary across species, vigilance states, or health conditions. While basal aspects of consciousness like perceptions and emotions are present in many states and species, higher-order aspects like reflective or volitional capabilities seem to be most pronounced in awake humans. Here we assess the experience of volition across different states of consciousness: 10 frequent lucid dreamers rated different aspects of volition according to the Volitional Components Questionnaire for phases of normal dreaming, lucid dreaming, and wakefulness. Overall, experienced volition was comparable for lucid dreaming and wakefulness, and rated significantly higher for both states compared to non-lucid dreaming. However, three subscales showed specific differences across states of consciousness: planning ability was most pronounced during wakefulness, intention enactment most pronounced during lucid dreaming, and self-determination most pronounced during both wakefulness and lucid dreaming. Our data confirm the multifaceted nature of consciousness: different higher-order aspects of consciousness are differentially expressed across different conscious states. PMID:24427149

Overall, experienced volition was comparable for lucid dreaming and wakefulness, and rated significantly higher for both states compared to non-lucid dreaming. However, three subscales showed specific differences across states of consciousness: planning ability was most pronounced during wakefulness, intention enactment most pronounced during lucid dreaming, and self-determination most pronounced during both wakefulness and lucid dreaming. Our data confirm the multifaceted nature of consciousness: different higher-order aspects of consciousness are differentially expressed across different conscious states.

Criticality reportedly describes brain dynamics. The main critical feature is the presence of scale-free neural avalanches, whose auto-organization is determined by a critical branching ratio of neural-excitation spreading. Other features, directly associated to second-order phase transitions, are: (i) scale-free-network topology of functional connectivity, stemming from suprathreshold pairwise correlations, superimposable, in waking brain activity, with that of ferromagnets at Curie temperature; (ii) temporal long-range memory associated to renewal intermittency driven by abrupt fluctuations in the order parameters, detectable in human brain via spatially distributed phase or amplitude changes in EEG activity. Herein we study intermittent events, extracted from 29 night EEG recordings, including presleep wakefulness and all phases of sleep, where different levels of mentation and consciousness are present. We show that while critical avalanching is unchanged, at least qualitatively, intermittency and functional connectivity, present during conscious phases (wakefulness and REM sleep), break down during both shallow and deep non-REM sleep. We provide a theory for fragmentation-induced intermittency breakdown and suggest that the main difference between conscious and unconscious states resides in the backwards causation, namely on the constraints that the emerging properties at large scale induce to the lower scales. In particular, while in conscious states this backwards causation induces a critical slowing down, preserving spatiotemporal correlations, in dreamless sleep we see a self-organized maintenance of moduli working in parallel. Critical avalanches are still present, and establish transient auto-organization, whose enhanced fluctuations are able to trigger sleep-protecting mechanisms that reinstate parallel activity. The plausible role of critical avalanches in dreamless sleep is to provide a rapid recovery of consciousness, if stimuli are highly arousing.

Using brain stimulation to disentangle neural correlates of conscious vision

2014-01-01

Research into the neural correlates of consciousness (NCCs) has blossomed, due to the advent of new and increasingly sophisticated brain research tools. Neuroimaging has uncovered a variety of brain processes that relate to conscious perception, obtained in a range of experimental paradigms. But methods such as functional magnetic resonance imaging or electroencephalography do not always afford inference on the functional role these brain processes play in conscious vision. Such empirical NCCs could reflect neural prerequisites, neural consequences, or neural substrates of a conscious experience. Here, we take a closer look at the use of non-invasive brain stimulation (NIBS) techniques in this context. We discuss and review how NIBS methodology can enlighten our understanding of brain mechanisms underlying conscious vision by disentangling the empirical NCCs. PMID:25295015

Spatial Frequency Tuning during the Conscious and Non-Conscious Perception of Emotional Facial Expressions – An Intracranial ERP Study

2012-01-01

Previous studies have shown that complex visual stimuli, such as emotional facial expressions, can influence brain activity independently of the observers’ awareness. Little is known yet, however, about the “informational correlates” of consciousness – i.e., which low-level information correlates with brain activation during conscious vs. non-conscious perception. Here, we investigated this question in the spatial frequency (SF) domain. We examined which SFs in disgusted and fearful faces modulate activation in the insula and amygdala over time and as a function of awareness, using a combination of intracranial event-related potentials (ERPs), SF Bubbles (Willenbockel et al., 2010a), and Continuous Flash Suppression (CFS; Tsuchiya and Koch, 2005). Patients implanted with electrodes for epilepsy monitoring viewed face photographs (13° × 7°) that were randomly SF filtered on a trial-by-trial basis. In the conscious condition, the faces were visible; in the non-conscious condition, they were rendered invisible using CFS. The data were analyzed by performing multiple linear regressions on the SF filters from each trial and the transformed ERP amplitudes across time. The resulting classification images suggest that many SFs are involved in the conscious and non-conscious perception of emotional expressions, with SFs between 6 and 10 cycles per face width being particularly important early on. The results also revealed qualitative differences between the awareness conditions for both regions. Non-conscious processing relied on low SFs more and was faster than conscious processing. Overall, our findings are consistent with the idea that different pathways are employed for the processing of emotional stimuli under different degrees of awareness. The present study represents a first step to mapping how SF information “flows” through the emotion-processing network with a high temporal resolution and to shedding light on the informational correlates of

A unity of the self or a multiplicity of locations? How the graphesthesia task sheds light on the role of spatial perspectives in bodily self-consciousness.

Integrating multisensory stimuli from a self-centred perspective is crucial for the unity of the self. On the other hand, understanding external space and communicating spatial knowledge with others necessitate the adoption of decentred perspectives. How do we juggle these two requirements? In this article, we review those studies that have used the graphesthesia task in order to investigate the perspectives that people adopt when interpreting ambiguous tactile symbols (e.g., b, d, p, and q). With such ambiguous symbols, self-centred and decentred perspectives conflict with one another. The results reviewed here reveal that the perspectives adopted vary significantly with spatial, personal, and interpersonal factors. Such findings suggest that the self can adopt a multiplicity of spatial locations. However, the unity of the self can partly be explained by the predominance of a head-centred perspective. On the other hand, perspective-taking abilities contribute to the distinction between self and others, reinforcing self-consciousness. Copyright © 2017 Elsevier Inc. All rights reserved.

[What is impaired consciousness? Revisiting impaired consciousness as psychiatric concept].

PubMed

Kanemoto, Kousuke

2004-01-01

For decades, psychiatrists have considered that concepts of impaired consciousness in the study of psychiatry were inconsistent with those applied in the field of neurology, in which the usefulness of the concept of consciousness has long been seriously doubted. Gloor concluded that the concept of consciousness does not further the understanding of seizure mechanisms or brain function, which is the current representative opinion of most epileptologists. Loss of consciousness tends to be reduced to aggregates of individual impairments of higher cognitive functions, and the concept of consciousness is preferably avoided by neurologists by assigning various behavioral disturbances during disturbed consciousness to particular neuropsychological centers. In contrast, psychiatrists, especially those in Europe, are more likely to include phenomena involving problems related to phenomenological intentionality in impaired consciousness. For the present study, we first divided consciousness into vigilance and recursive consciousness, and then attempted to determine what kind of impaired consciousness would be an ideal candidate to represent pure disturbance of recursive consciousness. Then, 4 patients, 1 each with pure amnestic states followed immediately by complex partial seizures, an akinetic mutistic state caused by absence status, and mental diplopia as a manifestation of postictal psychosis, as well as a patient with Alzheimer's disease who gracefully performed Japanese tea ceremony, were studied. Based on our findings, we concluded that impaired consciousness as a generic term in general medicine does not indicate any unitary entity corresponding to some well-demarcated physiological function or constitute a base from which recursive consciousness emerges as a superstructure. From that, we stressed that a pure form of impairment of recursive consciousness could occur without the impaired consciousness named generically in general medicine. Second, following

Shame on Me! Self-Conscious Emotions and Big Five Personality Traits and Their Relations to Anxiety Disorders Symptoms in Young, Non-Clinical Adolescents.

Muris, Peter; Meesters, Cor; van Asseldonk, Mike

2018-04-01

This study explored the relations between self-conscious emotions, personality traits, and anxiety disorders symptoms in non-clinical youths. One-hundred-and-eighteen adolescents aged 12-15 years completed the brief shame and guilt questionnaire for children (BSGQ-C) and items of the youth self-report (YSR) to measure shame and guilt, the big five personality questionnaire for children, and the youth anxiety measure for DSM-5. Results for shame indicated that this self-conscious emotion-either measured by the BSGQ-C or the YSR-was uniquely and positively associated with a broad range of anxiety disorders symptoms, and correlated positively with neuroticism and negatively with extraversion. Guilt did not show significant associations with anxiety disorders symptoms once controlling for the influence of shame, and links with personality traits varied dependent on the assessment instrument that was used (BSGQ-C or YSR). Finally, when controlling for neuroticism and extraversion, shame consistently remained a significant correlate of anxiety disorders symptoms. Altogether, these results add to the growing body of evidence indicating that high levels of shame are clearly associated with anxiety pathology.

Dynamic Connectivity Patterns in Conscious and Unconscious Brain

Ma, Yuncong; Hamilton, Christina

2017-01-01

Abstract Brain functional connectivity undergoes dynamic changes from the awake to unconscious states. However, how the dynamics of functional connectivity patterns are linked to consciousness at the behavioral level remains elusive. In this study, we acquired resting-state functional magnetic resonance imaging data during wakefulness and graded levels of consciousness in rats. Data were analyzed using a dynamic approach combining the sliding window method and k-means clustering. Our results demonstrate that whole-brain networks contained several quasi-stable patterns that dynamically recurred from the awake state into anesthetized states. Remarkably, two brain connectivity states with distinct spatial similarity to the structure of anatomical connectivity were strongly biased toward high and low consciousness levels, respectively. These results provide compelling neuroimaging evidence linking the dynamics of whole-brain functional connectivity patterns and states of consciousness at the behavioral level. PMID:27846731

Voluntary Genital Ablations: Contrasting the Cutters and Their Clients

2014-01-01

Introduction Some healthy males voluntarily seek castration without a recognized medical need. There are currently no standards of care for these individuals, which cause many of them to obtain surgery outside of a licensed medical setting. We seek to understand who performs these surgeries. Aim This study aims to characterize individuals who perform or assist in genital ablations outside of the healthcare system. Methods A cross-sectional Internet survey posted on eunuch.org received 2,871 responses. We identified individuals who had performed or assisted in human castrations (“cutters”; n = 98) and compared this group with all other survey respondents (n = 2,773), who had not assisted in castrations. Next we compared the cutters with the voluntary eunuchs. Lastly, because many of the cutters have themselves been castrated, we also divided the physically castrated population (n = 278) into cutters (n = 44) and noncutters (n = 234) and compared them. Main Outcome Measures Self-reported questionnaires were used to collect demographic information, gender identity and presentation, selected childhood experiences, and history of aggressive behaviors, self-harming behaviors, and hospitalization. Results Distinguishing characteristics of cutters included: (i) presenting themselves as very masculine, (ii) having had their longest sexual relationship with a man, (iii) growing up on a farm, (iv) witnessing animal castrations, (v) having a history of sexually inappropriate behavior, (vi) having been threatened with genital mutilation as a child, (vii) having a history of self-harm, (viii) being raised in a devoutly Christian household, (ix) having had an underground castration themselves, and (x) having body piercings and/or tattoos. Conclusions This study may help identify individuals who are at risk of performing illegal castrations. That information may help healthcare providers protect individuals with extreme castration ideations from injuring themselves or others

Distribution of female genital tract anomalies in two classifications.

PubMed

Heinonen, Pentti K

2016-11-01

This study assessed the distribution of Müllerian duct anomalies in two verified classifications of female genital tract malformations, and the presence of associated renal defects. 621 women with confirmed female genital tract anomalies were retrospectively grouped under the European (ESHRE/ESGE) and the American (AFS) classification. The diagnosis of uterine malformation was based on findings in hysterosalpingography, two-dimensional ultrasonography, endoscopies, laparotomy, cesarean section and magnetic resonance imaging in 97.3% of cases. Renal status was determined in 378 patients, including 5 with normal uterus and vagina. The European classification covered all 621 women studied. Uterine anomalies without cervical or vaginal anomaly were found in 302 (48.6%) patients. Uterine anomaly was associated with vaginal anomaly in 45.2%, and vaginal anomaly alone was found in 26 (4.2%) cases. Septate uterus was the most common (49.1%) of all genital tract anomalies, followed by bicorporeal uteri (18.2%). The American classification covered 590 (95%) out of the 621 women with genital tract anomalies. The American system did not take into account vaginal anomalies in 170 (34.7%) and cervical anomalies in 174 (35.5%) out of 490 cases with uterine malformations. Renal abnormalities were found in 71 (18.8%) out of 378 women, unilateral renal agenesis being the most common defect (12.2%), also found in 4 women without Müllerian duct anomaly. The European classification sufficiently covered uterine and vaginal abnormalities. The distribution of the main uterine anomalies was equal in both classifications. The American system missed cervical and vaginal anomalies associated with uterine anomalies. Evaluation of renal system is recommended for all patients with genital tract anomalies.

2016-01-01

Genital gender affirming surgery (GAS) involves reconstruction of the genitals to match a patient’s identified sex. The use of hair-bearing flaps in this procedure may result in postoperative intra-vaginal and intra-urethral hair growth and associated complications, including lower satisfaction with genital GAS. Despite the significant increase in genital GAS within the past 50 years, there is limited data regarding hair removal practices in preparation for genital GAS and notable variation in hair removal techniques among dermatologists and other practitioners. We present a literature review, recommendations from our experience, and a practical laser hair removal (LHR) approach to hair removal prior to genital GAS. PMID:27298787

An Education in Awareness: Self, Motivation, and Self-Regulated Learning in Contemplative Perspective

PubMed Central

Roeser, Robert W.; Peck, Stephen C.

2009-01-01

Consistent with the aims of this special issue, we present a systems perspective on self/identity, predicated on William James’s classic distinction between I and Me, and use this perspective to explore conceptual relations between self/identity, motivation to learn, and self-regulated learning. We define the I self functionally in terms of the capacity for the conscious shifting and sustaining of awareness. The I is conceived of as that aspect of the self-system that affords the potential for the conscious and willful, rather than the non-conscious and automatic, motivation and regulation of behavior. We introduce contemplative education as a set of pedagogical practices designed to cultivate conscious awareness in an ethical-relational context in which the values of personal growth, learning, moral living, and caring for others are nurtured. We discuss the implications of contemplative education for the cultivation of conscious and willful forms of learning and living among students and educators alike. PMID:20419040

The examination of the rape victim should focus on the therapeutic, forensic and psychological needs of the individual patient. One aspect will be an examination for ano-genital injuries. From a medical perspective, they tend to be minor and require little in the way of treatment. They must be considered when assessing the risk of blood-borne viruses and the need for prophylaxis. From a forensic perspective, an understanding of genital injury rates, type of injury, site and healing may assist the clinician to interpret the findings in the context of the allegations that have been made. There are many myths and misunderstandings about ano-genital injuries and rape. The clinician has a duty to dispel these. Copyright © 2012 Elsevier Ltd. All rights reserved.

Impact of Emotion on Consciousness: Positive Stimuli Enhance Conscious Reportability

Emotion and reward have been proposed to be closely linked to conscious experience, but empirical data are lacking. The anterior cingulate cortex (ACC) plays a central role in the hedonic dimension of conscious experience; thus potentially a key region in interactions between emotion and consciousness. Here we tested the impact of emotion on conscious experience, and directly investigated the role of the ACC. We used a masked paradigm that measures conscious reportability in terms of subjective confidence and objective accuracy in identifying the briefly presented stimulus in a forced-choice test. By manipulating the emotional valence (positive, neutral, negative) and the presentation time (16 ms, 32 ms, 80 ms) we measured the impact of these variables on conscious and subliminal (i.e. below threshold) processing. First, we tested normal participants using face and word stimuli. Results showed that participants were more confident and accurate when consciously seeing happy versus sad/neutral faces and words. When stimuli were presented subliminally, we found no effect of emotion. To investigate the neural basis of this impact of emotion, we recorded local field potentials (LFPs) directly in the ACC in a chronic pain patient. Behavioural findings were replicated: the patient was more confident and accurate when (consciously) seeing happy versus sad faces, while no effect was seen in subliminal trials. Mirroring behavioural findings, we found significant differences in the LFPs after around 500 ms (lasting 30 ms) in conscious trials between happy and sad faces, while no effect was found in subliminal trials. We thus demonstrate a striking impact of emotion on conscious experience, with positive emotional stimuli enhancing conscious reportability. In line with previous studies, the data indicate a key role of the ACC, but goes beyond earlier work by providing the first direct evidence of interaction between emotion and conscious experience in the human ACC.

Conscious experience and episodic memory: hippocampus at the crossroads.

PubMed

Behrendt, Ralf-Peter

2013-01-01

If an instance of conscious experience of the seemingly objective world around us could be regarded as a newly formed event memory, much as an instance of mental imagery has the content of a retrieved event memory, and if, therefore, the stream of conscious experience could be seen as evidence for ongoing formation of event memories that are linked into episodic memory sequences, then unitary conscious experience could be defined as a symbolic representation of the pattern of hippocampal neuronal firing that encodes an event memory - a theoretical stance that may shed light into the mind-body and binding problems in consciousness research. Exceedingly detailed symbols that describe patterns of activity rapidly self-organizing, at each cycle of the θ rhythm, in the hippocampus are instances of unitary conscious experience that jointly constitute the stream of consciousness. Integrating object information (derived from the ventral visual stream and orbitofrontal cortex) with contextual emotional information (from the anterior insula) and spatial environmental information (from the dorsal visual stream), the hippocampus rapidly forms event codes that have the informational content of objects embedded in an emotional and spatiotemporally extending context. Event codes, formed in the CA3-dentate network for the purpose of their memorization, are not only contextualized but also allocentric representations, similarly to conscious experiences of events and objects situated in a seemingly objective and observer-independent framework of phenomenal space and time. Conscious perception, creating the spatially and temporally extending world that we perceive around us, is likely to be evolutionarily related to more fleeting and seemingly internal forms of conscious experience, such as autobiographical memory recall, mental imagery, including goal anticipation, and to other forms of externalized conscious experience, namely dreaming and hallucinations; and evidence pointing to

Artificial consciousness and the consciousness-attention dissociation.

PubMed

Haladjian, Harry Haroutioun; Montemayor, Carlos

2016-10-01

Artificial Intelligence is at a turning point, with a substantial increase in projects aiming to implement sophisticated forms of human intelligence in machines. This research attempts to model specific forms of intelligence through brute-force search heuristics and also reproduce features of human perception and cognition, including emotions. Such goals have implications for artificial consciousness, with some arguing that it will be achievable once we overcome short-term engineering challenges. We believe, however, that phenomenal consciousness cannot be implemented in machines. This becomes clear when considering emotions and examining the dissociation between consciousness and attention in humans. While we may be able to program ethical behavior based on rules and machine learning, we will never be able to reproduce emotions or empathy by programming such control systems-these will be merely simulations. Arguments in favor of this claim include considerations about evolution, the neuropsychological aspects of emotions, and the dissociation between attention and consciousness found in humans. Ultimately, we are far from achieving artificial consciousness. Copyright © 2016 Elsevier Inc. All rights reserved.

Uncovering category specificity of genital sexual arousal in women: The critical role of analytic technique.

PubMed

Pulverman, Carey S; Hixon, J Gregory; Meston, Cindy M

2015-10-01

Based on analytic techniques that collapse data into a single average value, it has been reported that women lack category specificity and show genital sexual arousal to a large range of sexual stimuli including those that both match and do not match their self-reported sexual interests. These findings may be a methodological artifact of the way in which data are analyzed. This study examined whether using an analytic technique that models data over time would yield different results. Across two studies, heterosexual (N = 19) and lesbian (N = 14) women viewed erotic films featuring heterosexual, lesbian, and gay male couples, respectively, as their physiological sexual arousal was assessed with vaginal photoplethysmography. Data analysis with traditional methods comparing average genital arousal between films failed to detect specificity of genital arousal for either group. When data were analyzed with smoothing regression splines and a within-subjects approach, both heterosexual and lesbian women demonstrated different patterns of genital sexual arousal to the different types of erotic films, suggesting that sophisticated statistical techniques may be necessary to more fully understand women's genital sexual arousal response. Heterosexual women showed category-specific genital sexual arousal. Lesbian women showed higher arousal to the heterosexual film than the other films. However, within subjects, lesbian women showed significantly different arousal responses suggesting that lesbian women's genital arousal discriminates between different categories of stimuli at the individual level. Implications for the future use of vaginal photoplethysmography as a diagnostic tool of sexual preferences in clinical and forensic settings are discussed. © 2015 Society for Psychophysiological Research.

Current treatment of genital herpes is focused on ameliorating signs and symptoms but is not curative. However, as potential herpes simplex virus (HSV) cure approaches are tested in the laboratory, we aimed to assess the interest in such studies by persons with genital herpes and the willingness to assume risks associated with experimental therapy. We constructed an anonymous online questionnaire that was posted on websites that provide information regarding genital herpes. The questions collected demographic and clinical information on adults who self-reported as having genital herpes, and assessed attitudes toward and willingness to participate in HSV cure clinical research. Seven hundred eleven participants provided sufficient responses to be included in the analysis. Sixty-six percent were women; the median age was 37 years, and the median time since genital HSV diagnosis was 4.7 years. The willingness to participate in trials increased from 59.0% in phase 1 to 68.5% in phase 2, and 81.2% in phase 3 trials, and 40% reported willingness to participate even in the absence of immediate, personal benefits. The most desirable outcome was the elimination of risk for transmission to sex partner or neonate. The mean perceived severity of receiving a diagnosis of genital HSV-2 was 4.2 on a scale of 1 to 5. Despite suppressive therapy available, persons with genital herpes are interested in participating in clinical research aimed at curing HSV, especially in more advanced stages of development.

This study experimentally examined the impact of exposure to fitspiration images and self-compassion quotes on social media on young women's body satisfaction, body appreciation, self-compassion, and negative mood. Female undergraduate students (N=160) were randomly assigned to view either Instagram images of fitspiration, self-compassion quotes, a combination of both, or appearance-neutral images. Results showed no differences between viewing fitspiration images compared to viewing neutral images, except for poorer self-compassion among those who viewed fitspiration images. However, women who viewed self-compassion quotes showed greater body satisfaction, body appreciation, self-compassion, and reduced negative mood compared to women who viewed neutral images. Further, viewing a combination of fitspiration images and self-compassion quotes led to positive outcomes compared to viewing only fitspiration images. Trait levels of thin-ideal internalisation moderated some effects. The findings suggest that self-compassion might offer a novel avenue for attenuating the negative impact of social media on women's body satisfaction. Copyright © 2017 Elsevier Ltd.

Genital warts are one of the most common sexually transmitted diseases worldwide. The disease is a result of infection with low-risk types of human papillomaviruses, mostly type 6 and 11. Current therapies for genital warts are mainly ablative, or alternatively topical application of imiquimod cream and sinecatechin (polyphenon E) ointment to the warts. However, low patient compliance and high recurrence rate are significant problems for the treatment of genital warts by imiquimod and ablative therapies. We summarise recent literature in this area and propose combining imiquimod with other therapies to increase the efficacy of imiquimod.

Structured perceptual input imposes an egocentric frame of reference-pointing, imagery, and spatial self-consciousness.

Perceptual input imposes and maintains an egocentric frame of reference, which enables orientation. When blindfolded, people tended to mistake the assumed intrinsic axes of symmetry of their immediate environment (a room) for their own egocentric relation to features of the room. When asked to point to the door and window, known to be at mid-points of facing (or adjacent) walls, they pointed with their arms at 180 degrees (or 90 degrees) angles, irrespective of where they thought they were in the room. People did the same when requested to imagine the situation. They justified their responses (inappropriately) by logical necessity or a structural description of the room rather than (appropriately) by relative location of themselves and the reference points. In eight experiments, we explored the effect on this in perception and imagery of: perceptual input (without perceptibility of the target reference points); imaging oneself versus another person; aids to explicit spatial self-consciousness; order of questions about self-location; and the relation of targets to the axes of symmetry of the room. The results indicate that, if one is deprived of structured perceptual input, as well as losing one's bearings, (a) one is likely to lose one's egocentric frame of reference itself, and (b) instead of pointing to reference points, one demonstrates their structural relation by adopting the intrinsic axes of the environment as one's own. This is prevented by providing noninformative perceptual input or by inducing subjects to imagine themselves from the outside, which makes explicit the fact of their being located relative to the world. The role of perceptual contact with a structured world is discussed in relation to sensory deprivation and imagery, appeal is made to Gibson's theory of joint egoreception and exteroception, and the data are related to recent theories of spatial memory and navigation.

Self-recognition in retarded children.

PubMed

Hill, S D; Tomlin, C

1981-03-01

This study was designed to investigate the relationship between cognitive and affective development. Young preverbal retarded children watched TV images of themselves with faces marked or unmarked and of a peer whose face was marked. We used the objective technique of increased mark-directed responses as evidence of self-recognition and rated the children's reactions as they watched these images. The emergence of self-recognition was closely tied to the maturity of the children's general responsiveness to their reflections. The Down's syndrome children made a broad range of responses, including the curiosity and self-conscious behaviors characteristic of normal children during the second year of life, and all except one of these children showed evidence that they recognized their images. In contrast, the range of behaviors displayed by multihandicapped children was greatly restricted and similar to children in the first year of life. Less than half of these children showed an emergence of self-recognition.

Despite the high prevalence of genital pain in healthy young adult women, limited research has addressed genital pain during intercourse using contemporary models of multidimensional sexual function. The objectives of this study were threefold: (1) to identify differences in sexual functioning in women who experience genital pain compared to pain free women; (2) to identify predictors of sexual functioning in women with and without genital pain; and (3) to identify predictors of sexual satisfaction in women with and without genital pain. Sexually active female undergraduates (n = 651) were administered the Female Sexual Function Index and the Derogatis Sexual Functioning Inventory. We evaluated the sexual factors that impact the sexual function of women with any pain (including high and low pain groups) versus women with no history of pain. Women with genital pain reported greater rates of sexual dysfunction as compared to pain-free women; however, sexual functioning in the high versus low pain groups was distinguished primarily by vaginal lubrication. Women in the high pain group showed negative correlations between domains of sexual satisfaction and genital pain frequency and intensity that were not found in the low pain group. For pain-free women, intercourse played a strong role in sexual satisfaction, whereas non-intercourse sexual behavior was central to sexual satisfaction in women who reported pain. The evaluation of levels of genital pain may provide insight into the mechanisms underlying the impairment of sexual function, sexual behavior, and sexual satisfaction. PMID:17674182

In recent years, extensive endeavors have been paid to construct functional self-assembled nanomaterials for various applications such as catalysis, separation, energy and biomedicines. To date, different strategies have been developed for preparing nanomaterials with diversified structures and functionalities via fine tuning of self-assembled building blocks. In terms of biomedical applications, bioimaging technologies are urgently calling for high-efficient probes/contrast agents for high-performance bioimaging. Photoacoustic (PA) imaging is an emerging whole-body imaging modality offering high spatial resolution, deep penetration and high contrast in vivo. The self-assembled nanomaterials show high stability in vivo, specific tolerance to sterilization and prolonged half-life stability and desirable targeting properties, which is a kind of promising PA contrast agents for biomedical imaging. Herein, we focus on summarizing recent advances in smart self-assembled nanomaterials with NIR absorption as PA contrast agents for biomedical imaging. According to the preparation strategy of the contrast agents, the self-assembled nanomaterials are categorized into two groups, i.e., the ex situ and in situ self-assembled nanomaterials. The driving forces, assembly modes and regulation of PA properties of self-assembled nanomaterials and their applications for long-term imaging, enzyme activity detection and aggregation-induced retention (AIR) effect for diagnosis and therapy are emphasized. Finally, we conclude with an outlook towards future developments of self-assembled nanomaterials for PA imaging.

Episodic memory and autonoetic consciousness: a first-person approach.

PubMed Central

Gardiner, J M

2001-01-01

Episodic memory is identified with autonoetic consciousness, which gives rise to remembering in the sense of self-recollection in the mental re-enactment of previous events at which one was present. Autonoetic consciousness is distinguished from noetic consciousness, which gives rise to awareness of the past that is limited to feelings of familiarity or knowing. Noetic consciousness is identified not with episodic but with semantic memory, which involves general knowledge. A recently developed approach to episodic memory makes use of 'first-person' reports of remembering and knowing. Studies using this approach have revealed many independent variables that selectively affect remembering and others that selectively affect knowing. These studies can also be interpreted in terms of distinctiveness and fluency of processing. Remembering and knowing do not correspond with degrees of confidence in memory. Nor does remembering always control the memory response. There is evidence that remembering is selectively impaired in various populations, including not only amnesic patients and older adults but also adults with Asperger's syndrome. This first-person approach to episodic memory represents one way in which that most elusive aspect of consciousness, its subjectivity, can be investigated scientifically. The two kinds of conscious experiences can be manipulated experimentally in ways that are systematic, replicable and intelligible theoretically. PMID:11571027

Feminizing Genital Gender-Confirmation Surgery.

2018-02-14

For many patients with gender dysphoria, gender-confirmation surgery (GCS) helps align their physical characteristics with their gender identity and is a fundamental element of comprehensive treatment. This article is the 2nd in a 3-part series about the treatment of gender dysphoria. Non-operative management was covered in part 1. This section begins broadly by reviewing surgical eligibility criteria, benefits of GCS, and factors associated with regret for transgender men and women. Then, the scope narrows to focus on aspects of feminizing genital GCS, including a discussion of vaginoplasty techniques, complications, and sexual function outcomes. Part 3 features operative considerations for masculinizing genital GCS. To summarize the World Professional Association for Transgender Health's (WPATH) surgical eligibility criteria and describe how patients with gender dysphoria benefit from GCS, provide an overview of genital and non-genital feminizing gender-confirmation procedures, and review vaginoplasty techniques, preoperative considerations, complications, and outcomes. A review of relevant literature through April 2017 was performed using PubMed. Review of literature related to surgical eligibility criteria for GCS, benefits of GCS, and surgical considerations for feminizing genitoplasty. Most transgender men and women who satisfy WPATH eligibility criteria experience improved quality of life, overall happiness, and sexual function after GCS; regret is rare. Penile inversion vaginoplasty is the preferred technique for feminizing genital GCS according to most surgeons, including the authors whose surgical technique is described. Intestinal vaginoplasty is reserved for certain scenarios. After vaginoplasty most patients report overall high satisfaction with their sexual function even when complications occur, because most are minor and easily treatable. GCS alleviates gender dysphoria for appropriately selected transgender men and women. Preoperative

Female genital tract graft-versus-host disease (GVHD) is an under-recognized complication of allogeneic stem cell transplantation impacting on quality of life. We describe a prospective surveillance programme for female genital GVHD to better characterize incidence, risk factors and clinical features and the impact of a structured intervention policy. A retrospective audit was conducted on the medical records of all female transplant recipients surviving at least 6 months at a single centre over a 5-year period. Patients commenced topical vaginal oestrogen early post transplant with hormone replacement as appropriate for age, prior menopausal status and co-morbidities. A genital tract management programme included regular gynaecological review and self-maintenance of vaginal capacity by dilator or intercourse. The incidence of genital GVHD was 35% (95% confidence interval (CI) (25, 50%)) at 1 year and 49% (95% CI (36, 63%)) at 2 years. Topical therapy was effective in most cases; no patient required surgical intervention to divide vaginal adhesions. The main risk factor was stem cell source with peripheral blood progenitor cells posing a higher risk than marrow (hazard ratio=3.07 (1.22, 7.73), P=0.017). Extensive GVHD in other organs was a common association. We conclude that female genital GVHD is common, and early detection and commencement of topical immunosuppression with dilator use appears to be highly effective at preventing progression.

Is Schizophrenia a Disorder of Consciousness? Experimental and Phenomenological Support for Anomalous Unconscious Processing

PubMed Central

Giersch, Anne; Mishara, Aaron L.

2017-01-01

Decades ago, several authors have proposed that disorders in automatic processing lead to intrusive symptoms or abnormal contents in the consciousness of people with schizophrenia. However, since then, studies have mainly highlighted difficulties in patients’ conscious experiencing and processing but rarely explored how unconscious and conscious mechanisms may interact in producing this experience. We report three lines of research, focusing on the processing of spatial frequencies, unpleasant information, and time-event structure that suggest that impairments occur at both the unconscious and conscious level. We argue that focusing on unconscious, physiological and automatic processing of information in patients, while contrasting that processing with conscious processing, is a first required step before understanding how distortions or other impairments emerge at the conscious level. We then indicate that the phenomenological tradition of psychiatry supports a similar claim and provides a theoretical framework helping to understand the relationship between the impairments and clinical symptoms. We base our argument on the presence of disorders in the minimal self in patients with schizophrenia. The minimal self is tacit and non-verbal and refers to the sense of bodily presence. We argue this sense is shaped by unconscious processes, whose alteration may thus affect the feeling of being a unique individual. This justifies a focus on unconscious mechanisms and a distinction from those associated with consciousness. PMID:29033868

Synthetic consciousness: the distributed adaptive control perspective

PubMed Central

2016-01-01

Understanding the nature of consciousness is one of the grand outstanding scientific challenges. The fundamental methodological problem is how phenomenal first person experience can be accounted for in a third person verifiable form, while the conceptual challenge is to both define its function and physical realization. The distributed adaptive control theory of consciousness (DACtoc) proposes answers to these three challenges. The methodological challenge is answered relative to the hard problem and DACtoc proposes that it can be addressed using a convergent synthetic methodology using the analysis of synthetic biologically grounded agents, or quale parsing. DACtoc hypothesizes that consciousness in both its primary and secondary forms serves the ability to deal with the hidden states of the world and emerged during the Cambrian period, affording stable multi-agent environments to emerge. The process of consciousness is an autonomous virtualization memory, which serializes and unifies the parallel and subconscious simulations of the hidden states of the world that are largely due to other agents and the self with the objective to extract norms. These norms are in turn projected as value onto the parallel simulation and control systems that are driving action. This functional hypothesis is mapped onto the brainstem, midbrain and the thalamo-cortical and cortico-cortical systems and analysed with respect to our understanding of deficits of consciousness. Subsequently, some of the implications and predictions of DACtoc are outlined, in particular, the prediction that normative bootstrapping of conscious agents is predicated on an intentionality prior. In the view advanced here, human consciousness constitutes the ultimate evolutionary transition by allowing agents to become autonomous with respect to their evolutionary priors leading to a post-biological Anthropocene. This article is part of the themed issue ‘The major synthetic evolutionary transitions’. PMID

A Model of Female Sexual Desire: Internalized Working Models of Parent-Child Relationships and Sexual Body Self-Representations.

PubMed

Cherkasskaya, Eugenia; Rosario, Margaret

2017-11-01

The etiology of low female sexual desire, the most prevalent sexual complaint in women, is multi-determined, implicating biological and psychological factors, including women's early parent-child relationships and bodily self-representations. The current study evaluated a model that hypothesized that sexual body self-representations (sexual subjectivity, self-objectification, genital self-image) explain (i.e., mediate) the relation between internalized working models of parent-child relationships (attachment, separation-individuation, parental identification) and sexual desire in heterosexual women. We recruited 614 young, heterosexual women (M = 25.5 years, SD = 4.63) through social media. The women completed an online survey. Structural equation modeling was used. The hypotheses were supported in that the relation between internalized working models of parent-child relationships (attachment and separation-individuation) and sexual desire was mediated by sexual body self-representations (sexual body esteem, self-objectification, genital self-image). However, parental identification was not related significantly to sexual body self-representations or sexual desire in the model. Current findings demonstrated that understanding female sexual desire necessitates considering women's internalized working models of early parent-child relationships and their experiences of their bodies in a sexual context. Treatment of low or absent desire in women would benefit from modalities that emphasize early parent-child relationships as well as interventions that foster mind-body integration.

We aimed to describe the presentation of long-term complications of female genital mutilation/cutting and the surgical management of clitoral keloids secondary to female genital mutilation/cutting. Twenty-seven women who underwent surgery because of clitoral keloid between May 2014 and September 2015 in Sudan Nyala Turkish Hospital were evaluated in this retrospective descriptive case series study. The prevalence of type 1, type 2, and type 3 female genital mutilation/cutting were 3.7%, 22.2%, and 74.1%, respectively (type 1: 1/27, type 2: 6/27, and type 3: 20/27). All patients had long-term health problems (dysuria, chronic pelvic pain, vaginal discharge, and chronic pruritus) and sexual dysfunction. Keloids were removed by surgical excision. There were no postoperative complications in any patient. Although clitoral keloid lesions can be seen after any type of female genital mutilation/cutting, they usually develop after type 3 female genital mutilation/cutting. Most of these keloids were noticed after menarche. Keloids can be removed by surgical excision and this procedure can alleviate some long-term morbidities of female genital mutilation/cutting.

Whether unique human immunodeficiency type 1 (HIV) genotypes occur in the genital tract is important for vaccine development and management of drug resistant viruses. Multiple cross-sectional studies suggest HIV is compartmentalized within the female genital tract. We hypothesize that bursts of HIV replication and/or proliferation of infected cells captured in cross-sectional analyses drive compartmentalization but over time genital-specific viral lineages do not form; rather viruses mix between genital tract and blood. Eight women with ongoing HIV replication were studied during a period of 1.5 to 4.5 years. Multiple viral sequences were derived by single-genome amplification of the HIV C2-V5 region of env from genital secretions and blood plasma. Maximum likelihood phylogenies were evaluated for compartmentalization using 4 statistical tests. In cross-sectional analyses compartmentalization of genital from blood viruses was detected in three of eight women by all tests; this was associated with tissue specific clades containing multiple monotypic sequences. In longitudinal analysis, the tissues-specific clades did not persist to form viral lineages. Rather, across women, HIV lineages were comprised of both genital tract and blood sequences. The observation of genital-specific HIV clades only in cross-sectional analysis and an absence of genital-specific lineages in longitudinal analyses suggest a dynamic interchange of HIV variants between the female genital tract and blood.

1999-08-01

This study examined the relationship between self-image and ethnic identification among 3 South African groups. Participants included random samples of 347 Afrikaans-speaking Whites, 113 English-speaking Whites, and 466 Blacks in urban Gauteng. Positive and negative self-image were extracted using the Rosenberg Self-Esteem Scale (M. Rosenberg, 1965). Afrikaans-speaking Whites had the most positive self-image and Blacks the most negative self-image. A positive self-image was correlated with stronger ethnic identification among Afrikaans-speaking Whites. The opposite was true for Blacks. This relationship was insignificant among English-speaking Whites. Ambivalence toward ingroup identity was persistently correlated with self-image for all groups.

To measure the effect on genital warts of the national human papillomavirus vaccination programme in Australia, which started in mid-2007. Trend analysis of national surveillance data. Data collated from eight sexual health services from 2004 to 2011; the two largest clinics also collected self reported human papillomavirus vaccination status from 2009. Between 2004 and 2011, 85,770 Australian born patients were seen for the first time; 7686 (9.0%) were found to have genital warts. Rate ratios comparing trends in proportion of new patients diagnosed as having genital warts in the pre-vaccination period (2004 to mid-2007) and vaccination period (mid-2007 to the end of 2011). Large declines occurred in the proportions of under 21 year old (92.6%) and 21-30 year old (72.6%) women diagnosed as having genital warts in the vaccination period-from 11.5% in 2007 to 0.85% in 2011 (P<0.001) and from 11.3% in 2007 to 3.1% in 2011 (P<0.001), respectively. No significant decline in wart diagnoses was seen in women over 30 years of age. Significant declines occurred in proportions of under 21 year old (81.8%) and 21-30 year old (51.1%) heterosexual men diagnosed as having genital warts in the vaccination period-from 12.1% in 2007 to 2.2% in 2011 (P<0.001) and from 18.2% in 2007 to 8.9% in 2011 (P<0.001), respectively. No significant decline in genital wart diagnoses was seen in heterosexual men over 30 years of age. In 2011 no genital wart diagnoses were made among 235 women under 21 years of age who reported prior human papillomavirus vaccination. The significant declines in the proportion of young women found to have genital warts and the absence of genital warts in vaccinated women in 2011 suggests that the human papillomavirus vaccine has a high efficacy outside of the trial setting. Large declines in diagnoses of genital warts in heterosexual men are probably due to herd immunity.

A Heuristic Model of Consciousness with Applications to the Development of Science and Society

NASA Technical Reports Server (NTRS)

Curreri, Peter A.

2010-01-01

A working model of consciousness is fundamental to understanding of the interactions of the observer in science. This paper examines contemporary understanding of consciousness. A heuristic model of consciousness is suggested that is consistent with psycophysics measurements of bandwidth of consciousness relative to unconscious perception. While the self reference nature of consciousness confers a survival benefit by assuring the all points of view regarding a problem are experienced in sufficiently large population, conscious bandwidth is constrained by design to avoid chaotic behavior. The multiple hypotheses provided by conscious reflection enable the rapid progression of science and technology. The questions of free will and the problem of attention are discussed in relation to the model. Finally the combination of rapid technology growth with the assurance of many unpredictable points of view is considered in respect to contemporary constraints to the development of society.

Body image and borderline personality disorder among psychiatric inpatients.

Sansone, Randy A; Chu, Jamie W; Wiederman, Michael W

2010-01-01

With the exclusion of studies in individuals with eating disorders, few investigators have examined body image issues in patients with borderline personality disorder (BPD). In this study, we examined among psychiatric inpatients relationships between body image and BPD. In a cross-sectional sample of convenience, we surveyed 126 women in an inpatient psychiatric unit using 5 measures for body image and 2 measures for BPD. Using standardized cutoffs for BPD diagnosis, participants with BPD demonstrated a number of differentiating features with regard to body image issues. Explicitly, BPD did not seem to be related to being self-conscious about one's appearance, although BPD was related to being more self-conscious, in general. Individuals with BPD were not more invested in their appearance as a source of self-definition but evaluated their own appearance more negatively and were more likely to believe that attractiveness is an important factor for happiness and acceptance. Although BPD was not related to perceptions about the strength and competence of one's own body, those with BPD indicated less comfort and trust in their own bodies. In general, it appeared that body image measures that were more perceptually grounded were more likely to be similar to non-BPD participants, whereas body image measures that were more cognitively grounded were more likely to be statistically significantly different in comparison with non-BPD participants. Psychiatric inpatients with BPD demonstrate a number of disturbances in body image. Copyright © 2010 Elsevier Inc. All rights reserved.

Female genital mutilation.

PubMed

Ladjali, M; Rattray, T W; Walder, R J

1993-08-21

Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees.

Genital contact allergy: A diagnosis missed

Genital allergy should be considered as a possible diagnosis in all patients with genital soreness or irritation for which no infection or dermatosis can be identified and in whom symptoms remain unchanged or worsen with treatment. It is an underreported and underdiagnosed condition as patients may not complain about symptoms in this area. Moreover, diagnosis and therapy may not often be conducted by a dermatologist or allergologist. Therefore, many cases of allergic diseases in the genital area remain undetected. PMID:27190404

Consciousness can only be measured through first-person reports, which raises problems about the accuracy of first-person reports, the possibility of non-reportable consciousness and the causal closure of the physical world. Many of these issues could be resolved by assuming that consciousness is entirely physical or functional. However, this would sacrifice the theory-neutrality that is a key attraction of a correlates-based approach to the study of consciousness. This paper puts forward a different solution that uses a framework of definitions and assumptions to explain how consciousness can be measured. This addresses the problems associated with first-person reports and avoids the issues with the causal closure of the physical world. This framework is compatible with most of the current theories of consciousness and it leads to a distinction between two types of correlates of consciousness. PMID:25071677

Many recent behavioral and neuroscientific studies have revealed the importance of investigating meditation states and traits to achieve an increased understanding of cognitive and affective neuroplasticity, attention and self-awareness, as well as for their increasingly recognized clinical relevance. The investigation of states and traits related to meditation has especially pronounced implications for the neuroscience of attention, consciousness, self-awareness, empathy and theory of mind. In this article we present the main features of meditation-based mental training and characterize the current scientific approach to meditation states and traits with special reference to attention and consciousness, in light of the articles contributed to this issue.

Drinking and desired self-images: path models of self-image goals, coping motives, heavy-episodic drinking, and alcohol problems.

Coping motives for drinking initiate alcohol-related problems. Interpersonal goals, which powerfully influence affect, could provide a starting point for this relation. Here we tested effects of self-image goals (which aim to construct and defend desired self-views) and compassionate goals (which aim to support others) on heavy-episodic drinking and alcohol-related problems. Undergraduate drinkers (N=258) completed measures of self-image and compassionate goals in academics and friendships, coping and enhancement drinking motives, heavy-episodic drinking, and alcohol-related problems in a cross-sectional design. As predicted, self-image goals, but not compassionate goals, positively related to alcohol-related problems. Path models showed that self-image goals relate to coping motives, but not enhancement motives; coping motives then relate to heavy-episodic drinking, which in turn relate to alcohol-related problems. Self-image goals remained a significant predictor in the final model, which accounted for 34% of the variance in alcohol-related problems. These findings indicate that self-image goals contribute to alcohol-related problems in college students both independently and through coping motives. Interventions can center on reducing self-image goals and their attendant negative affect. Copyright (c) 2009 APA, all rights reserved.

Background. Whether unique human immunodeficiency type 1 (HIV) genotypes occur in the genital tract is important for vaccine development and management of drug resistant viruses. Multiple cross-sectional studies suggest HIV is compartmentalized within the female genital tract. We hypothesize that bursts of HIV replication and/or proliferation of infected cells captured in cross-sectional analyses drive compartmentalization but over time genital-specific viral lineages do not form; rather viruses mix between genital tract and blood. Methods. Eight women with ongoing HIV replication were studied during a period of 1.5 to 4.5 years. Multiple viral sequences were derived by single-genome amplification of the HIV C2-V5 region of env from genital secretions and blood plasma. Maximum likelihood phylogenies were evaluated for compartmentalization using 4 statistical tests. Results. In cross-sectional analyses compartmentalization of genital from blood viruses was detected in three of eight women by all tests; this was associated with tissue specific clades containing multiple monotypic sequences. In longitudinal analysis, the tissues-specific clades did not persist to form viral lineages. Rather, across women, HIV lineages were comprised of both genital tract and blood sequences. Conclusions. The observation of genital-specific HIV clades only in cross-sectional analysis and an absence of genital-specific lineages in longitudinal analyses suggest a dynamic interchange of HIV variants between the female genital tract and blood.

From the advent of digital imaging through several decades of studies, the human vision research community systematically focused on perceived image quality and digital artifacts due to resolution, compression, gamma, dynamic range, capture and reproduction noise, blur, etc., to help overcome existing technological challenges and shortcomings. Technological advances made digital images and digital multimedia nearly flawless in quality, and ubiquitous and pervasive in usage, provide us with the exciting but at the same time demanding possibility to turn to the domain of human experience including higher psychological functions, such as cognition, emotion, awareness, social interaction, consciousness and Self. In this paper we will outline the evolution of human centered multidisciplinary studies related to imaging and propose steps and potential foci of future research.

Diagnosis of consciousness can be very challenging in some clinical situations such as severe sensory-motor impairments. We report the case study of a patient who presented a total "locked-in syndrome" associated with and a multi-sensory deafferentation (visual, auditory and tactile modalities) following a protuberantial infarction. In spite of this severe and extreme disconnection from the external world, we could detect reliable evidence of consciousness using a multivariate analysis of his high-density resting state electroencephalogram. This EEG-based diagnosis was eventually confirmed by the clinical evolution of the patient. This approach illustrates the potential importance of functional brain-imaging data to improve diagnosis of consciousness and of cognitive abilities in critical situations in which the behavioral channel is compromised such as deafferented locked-in syndrome.

Is Your Gut Conscious? Is an Extraterrestrial?

This paper speculates on questions intending to be taken scientifically rather than metaphysically: "Can the human gut (enteric nervous system) be conscious?"; "Can your immune system think?"; "Could consciousness be coded in DNA?"; "What do we mean when asserting that an Extraterrestrial is Thinking, or is Conscious? We explore through reference to theory, experiment, and computational models by Christof Koch (Caltech), Barbara Wold (Caltech), and Stuart Kauffman (University of Calgary, Tampere University of Technology, Santa Fe Institute). We use a tentative new definition of thinking, designed to be applicable for humans, cetecea, corvids, artificial intelligences, and extraterrestrial intelligences of any substrate (i.e. Life as We Do Not Know It): "Thinking is the occurrence, transformation, and storage in a mind or brain (or simulation thereof) of information-bearing structures (representations) of one kind or another, such as thoughts, concept, percepts, ideas, impressions, notions, rules, schemas, images, phantasms, or subpersonal representations." We use the framework for Consciousness developed by Francis Crick and Christof Koch. We try to describe scientific goals, but discuss Philosophy sufficient to avoid naïve philosophical category errors (thus are careful not to conflate thought, consciousness, and language) Penrose, Hameroff, and Kauffman speculate (differently) that CNS consciousness is a macroscopic quantum phenomenon. Might intestinal, immune system, or genetic regulatory network dynamics exhibit emergent cooperative quantum effects? The speculations are in the context of Evolution by Natural Selection, presumed to operate throughout the Cosmos, and recent work in the foundations of Computational Biology and Quantum Mechanics.

Phenotypic engineering unveils the function of genital morphology.

The rapidly evolving and often extraordinarily complex appearance of male genital morphology of internally fertilizing animals has been recognized for centuries. Postcopulatory sexual selection is regarded as the likely evolutionary engine of this diversity, but direct support for this hypothesis is limited. We used two complementary approaches, evolution through artificial selection and microscale laser surgery, to experimentally manipulate genital morphology in an insect model system. We then assessed the competitive fertilization success of these phenotypically manipulated males and studied the fate of their ejaculate in females using high-resolution radioisotopic labeling of ejaculates. Males with longer genital spines were more successful in gaining fertilizations, providing experimental evidence that male genital morphology influences success in postcopulatory reproductive competition. Furthermore, a larger proportion of the ejaculate moved from the reproductive tract into the female body following mating with males with longer spines, suggesting that genital spines increase the rate at which seminal fluid passes into the female hemolymph. Our results show that genital morphology affects male competitive fertilization success and imply that sexual selection on genital morphology may be mediated in part through seminal fluid.

Psychophysiology of dissociated consciousness.

PubMed

Bob, Petr

2014-01-01

Recent study of consciousness provides an evidence that there is a limit of consciousness, which presents a barrier between conscious and unconscious processes. This barrier likely is specifically manifested as a disturbance of neural mechanisms of consciousness that through distributed brain processing, attentional mechanisms and memory processes enable to constitute integrative conscious experience. According to recent findings a level of conscious integration may change during certain conditions related to experimental cognitive manipulations, hypnosis, or stressful experiences that can lead to dissociation of consciousness. In psychopathological research the term dissociation was proposed by Pierre Janet for explanation of processes related to splitting of consciousness due to traumatic events or during hypnosis. According to several recent findings dissociation of consciousness likely is related to deficits in global distribution of information and may lead to heightened levels of "neural complexity" that reflects brain integration or differentiation based on numbers of independent neural processes in the brain that may be specifically related to various mental disorders.

To examine the association between schistosomiasis and reproductive tract symptoms. A cross-sectional study was conducted in a Schistosoma haematobium-endemic area of rural Zimbabwe. A total of 483 permanently resident adult women of Mupfure Ward aged 20-49 were interviewed and examined clinically, each providing three consecutive urine samples. Logistic regression analysis was used to control for sexually transmitted diseases (STDs). Women with genital sandy patches had significantly more genital itch (P = 0.009) and perceived their discharge as abnormal (P = 0.003). Eighty percent of the women who had genital itch, yellow discharge, and childhood or current waterbody contact had sandy patches. Fifty-two percent of the women with genital sandy patches did not have detectable S. haematobium ova in urine. Genital schistosomiasis was associated with stress incontinence and pollakisuria, but not with menstrual irregularities, current or previous ulcers, or tumours. Genital schistosomiasis may be a differential diagnosis to the STDs in women who have been exposed to fresh water in endemic areas. Because of the chronic nature of the disease in adults, we suggest to pay special attention to the prevention of morbidity.

Conscious perception relies on interactions between spatially and functionally distinct modules of the brain at various spatiotemporal scales. These interactions are altered by anesthesia, an intervention that leads to fading consciousness. Relatively little is known about brain functional connectivity and its anesthetic modulation at a fine spatial scale. Here, we used functional imaging to examine propofol-induced changes in functional connectivity in brain networks defined at a fine-grained parcellation based on a combination of anatomical and functional features. Fifteen healthy volunteers underwent resting-state functional imaging in wakeful baseline, mild sedation, deep sedation, and recovery of consciousness. Compared with wakeful baseline, propofol produced widespread, dose-dependent functional connectivity changes that scaled with the extent to which consciousness was altered. The dominant changes in connectivity were associated with the frontal lobes. By examining node pairs that demonstrated a trend of functional connectivity change between wakefulness and deep sedation, quadratic discriminant analysis differentiated the states of consciousness in individual participants more accurately at a fine-grained parcellation (e.g., 2000 nodes) than at a coarse-grained parcellation (e.g., 116 anatomical nodes). Our study suggests that defining brain networks at a high granularity may provide a superior imaging-based distinction of the graded effect of anesthesia on consciousness.

Evolution of human brain functions: the functional structure of human consciousness.

PubMed

Cloninger, C Robert

2009-11-01

The functional structure of self-aware consciousness in human beings is described based on the evolution of human brain functions. Prior work on heritable temperament and character traits is extended to account for the quantum-like and holographic properties (i.e. parts elicit wholes) of self-aware consciousness. Cladistic analysis is used to identify the succession of ancestors leading to human beings. The functional capacities that emerge along this lineage of ancestors are described. The ecological context in which each cladogenesis occurred is described to illustrate the shifting balance of evolution as a complex adaptive system. Comparative neuroanatomy is reviewed to identify the brain structures and networks that emerged coincident with the emergent brain functions. Individual differences in human temperament traits were well developed in the common ancestor shared by reptiles and humans. Neocortical development in mammals proceeded in five major transitions: from early reptiles to early mammals, early primates, simians, early Homo, and modern Homo sapiens. These transitions provide the foundation for human self-awareness related to sexuality, materiality, emotionality, intellectuality, and spirituality, respectively. The functional structure of human self-aware consciousness is concerned with the regulation of five planes of being: sexuality, materiality, emotionality, intellectuality, and spirituality. Each plane elaborates neocortical functions organized around one of the five special senses. The interactions among these five planes gives rise to a 5 x 5 matrix of subplanes, which are functions that coarsely describe the focus of neocortical regulation. Each of these 25 neocortical functions regulates each of five basic motives or drives that can be measured as temperaments or basic emotions related to fear, anger, disgust, surprise, and happiness/sadness. The resulting 5 x 5 x 5 matrix of human characteristics provides a general and testable model of the

The quadrivalent human papillomavirus (HPV) vaccine is effective against HPV types responsible for 90% of anogenital warts. This study estimated the quality of life lost to genital warts using the EQ-5D, a generic instrument widely used for applications in economic analyses. The findings are described in terms that are more specific to individuals with genital warts using psychosocial questions adapted from the HPV impact profile, a measure developed for HPV-related conditions. Between September 2006 and February 2008, 42 physicians across Canada recruited 330 consenting patients 18 years and older with genital warts, either at the first or follow-up visit for an initial or recurrent episode. The quality of life lost associated with genital warts was estimated by the difference between participants' EQ-5D scores and age and gender-specific population norms. The study questionnaire was self-completed by 270 participants who were aged 31.5 years (SD 10.4) on average. The majority of participants were women (53.3%), heterosexual (93.5%) and in a stable relationship (66.0%). Genital warts were associated with detriments in the EQ-5D domains of anxiety/depression, pain/discomfort and usual activities. The absolute difference in the EQ-5D utility score and the EQ-VAS health status between genital warts patients and population norms was 9.9 (95% CI 7.3 to 12.5) and 6.0 (95% CI 4.1 to 7.9) percentage points, respectively. These results did not vary significantly according to patient age, gender, time since first episode or number of episodes. The results suggest that genital warts negatively affect the wellbeing of men and women as reflected by poorer quality of life scores compared with population norms.

This paper presents the amplitude and phase imaging of onion epidermis cell using the self-imaging capabilities of a grating (Talbot effect) in visible light region. In proposed method, the Fresnel diffraction pattern from the first grating and object is recorded at self-image plane. Fast Fourier Transform (FFT) is used for extracting the 3D amplitude and phase image of onion epidermis cell. The stability of the proposed system, from environmental perturbation as well as its compactness and portability give the proposed system a high potential for several clinical applications.

Noninvasive assessment of vascular structure and function in conscious rats based on in vivo imaging of the albino iris

Experimental techniques allowing longitudinal studies of vascular disease progression or treatment effects are not readily available for most animal models. Thus, most existing studies are destined to either study individual time points or use large cohorts of animals. Here we describe a noninvasive technique for studying vascular disease that is based on in vivo imaging of the long posterior ciliary artery (LPCA) in the iris of albino rats. Using a slit-lamp biomicroscope, images of the LPCA were taken weekly in conscious normotensive Wistar Kyoto rats (WKY, n = 10) and spontaneously hypertensive rats (SHR, n = 10) for 10 wk. Using imaging software, we found that lumen diameter was significantly smaller and the wall-to-lumen (W/L) ratio larger in SHR than in WKY. Wall thickness was not different. Blood pressure correlated with the W/L ratio. Histology of the abdominal aorta also revealed a smaller lumen diameter and greater W/L ratio in SHR compared with WKY. Corneal application of the muscarinic receptor agonist pilocarpine elicited a dose-dependent vasodilation of the LPCA that could be antagonized by inhibition of nitric oxide synthase, suggesting that the pilocarpine response is mainly mediated by endothelium-derived nitric oxide. Consistent with endothelial dysfunction in SHR, pilocarpine-induced vasodilation was greater in WKY rats than in SHR. These findings indicate that in vivo imaging of the LPCA allows assessment of several structural and functional vascular parameters in conscious rats and that the LPCA responds to disease insults and pharmacologic treatments in a fashion that will make it a useful model for further studies.

This study explores the association between private and public body consciousness and past 30-day cigarette, alcohol, marijuana, and hard drug use among adolescents. Self-reported data from alterative high school students in California were analyzed (N = 976) using multilevel regression models to account for student clustering within schools. Separate regression analyses were conducted for males and females. Both cross-sectional baseline data and one-year longitudinal prediction models indicated that body consciousness is associated with specific drug use categories differentially by gender. Findings suggest that body consciousness accounts for additional variance in substance use etiology not explained by previously recognized dispositional variables.

Predicting Visual Consciousness Electrophysiologically from Intermittent Binocular Rivalry

PubMed Central

O’Shea, Robert P.; Kornmeier, Jürgen; Roeber, Urte

2013-01-01

Purpose We sought brain activity that predicts visual consciousness. Methods We used electroencephalography (EEG) to measure brain activity to a 1000-ms display of sine-wave gratings, oriented vertically in one eye and horizontally in the other. This display yields binocular rivalry: irregular alternations in visual consciousness between the images viewed by the eyes. We replaced both gratings with 200 ms of darkness, the gap, before showing a second display of the same rival gratings for another 1000 ms. We followed this by a 1000-ms mask then a 2000-ms inter-trial interval (ITI). Eleven participants pressed keys after the second display in numerous trials to say whether the orientation of the visible grating changed from before to after the gap or not. Each participant also responded to numerous non-rivalry trials in which the gratings had identical orientations for the two eyes and for which the orientation of both either changed physically after the gap or did not. Results We found that greater activity from lateral occipital-parietal-temporal areas about 180 ms after initial onset of rival stimuli predicted a change in visual consciousness more than 1000 ms later, on re-presentation of the rival stimuli. We also found that less activity from parietal, central, and frontal electrodes about 400 ms after initial onset of rival stimuli predicted a change in visual consciousness about 800 ms later, on re-presentation of the rival stimuli. There was no such predictive activity when the change in visual consciousness occurred because the stimuli changed physically. Conclusion We found early EEG activity that predicted later visual consciousness. Predictive activity 180 ms after onset of the first display may reflect adaption of the neurons mediating visual consciousness in our displays. Predictive activity 400 ms after onset of the first display may reflect a less-reliable brain state mediating visual consciousness. PMID:24124536

Sacral myeloradiculitis complicating genital herpes in a HIV-infected patient.

Myeloradiculitis is a rare neurological complication of herpes simplex type 2 (HSV-2) infection, frequently associated with a fatal outcome. Among patients with HIV infection, HSV-2 myeloradiculitis has occasionally been reported, always associated with advanced immunosuppression and AIDS. We report a patient with HIV infection but no history of previous opportunistic infections, who developed sacral myeloradiculitis immediately after an episode of genital herpes. Magnetic resonance imaging with gadolinium showed necrotizing myelitis in the conus medullaris and enhancement of sacral roots. CD4 lymphocyte count was 530/mm3. Other possible causes of myeloradiculitis in HIV-infected patients were appropriately excluded. Acyclovir therapy resulted in partial clinical improvement. This report shows that myeloradiculitis as a complication of genital herpes may occur in the early stages of HIV infection and may have a favourable outcome with antiviral treatment.

Free will as relative freedom with conscious component.

PubMed

Hájícek, P

2009-03-01

The general notion of relative freedom is introduced. It is a kind of freedom that is observed everywhere in nature. In biology, incomplete knowledge is defined for all organisms. They cope with the problem by Popper's trial-and-error processes. One source of their success is the relative freedom of choice from the basic option ranges: mutations, motions and neuron connections. After the conjecture is adopted that communicability can be used as a criterion of consciousness, free will is defined as a conscious version of relative freedom. The resulting notion is logically self-consistent and it describes an observable phenomenon that agrees with our experience.

Spontaneous brain activity has recently received increasing interest in the neuroimaging community. However, the value of resting-state studies to a better understanding of brain–behavior relationships has been challenged. That altered states of consciousness are a privileged way to study the relationships between spontaneous brain activity and behavior is proposed, and common resting-state brain activity features observed in various states of altered consciousness are reviewed. Early positron emission tomography studies showed that states of extremely low or high brain activity are often associated with unconsciousness. However, this relationship is not absolute, and the precise link between global brain metabolism and awareness remains yet difficult to assert. In contrast, voxel-based analyses identified a systematic impairment of associative frontoparieto–cingulate areas in altered states of consciousness, such as sleep, anesthesia, coma, vegetative state, epileptic loss of consciousness, and somnambulism. In parallel, recent functional magnetic resonance imaging studies have identified structured patterns of slow neuronal oscillations in the resting human brain. Similar coherent blood oxygen level–dependent (BOLD) systemwide patterns can also be found, in particular in the default-mode network, in several states of unconsciousness, such as coma, anesthesia, and slow-wave sleep. The latter results suggest that slow coherent spontaneous BOLD fluctuations cannot be exclusively a reflection of conscious mental activity, but may reflect default brain connectivity shaping brain areas of most likely interactions in a way that transcends levels of consciousness, and whose functional significance remains largely in the dark.

Current thinking on genital herpes.

Hofstetter, Annika M; Rosenthal, Susan L; Stanberry, Lawrence R

2014-02-01

Genital herpes has a high global prevalence and burden of disease. This manuscript highlights recent advances in our understanding of genital herpes simplex virus (HSV) infections. Studies demonstrate a changing epidemiological landscape with an increasing proportion of genital herpes cases associated with HSV type 1. There is also growing evidence that the majority of infected individuals exhibit frequent, brief shedding episodes that are most often asymptomatic, which likely contribute to high HSV transmission rates. Given this finding as well as readily available serological assays, some have proposed that routine HSV screening be performed; however, this remains controversial and is not currently recommended. Host immune responses, particularly local CD4 and CD8 T cell activity, are crucial for HSV control and clearance following initial infection, during latency and after reactivation. Prior HSV immunity may also afford partial protection against HSV reinfection and disease. Although HSV vaccine trials have been disappointing to date and existing antiviral medications are limited, novel prophylactic and therapeutic modalities are currently in development. Although much remains unknown about genital herpes, improved knowledge of HSV epidemiology, pathogenesis and host immunity may help guide new strategies for disease prevention and control.

Purpose and Methods: This is a series of three cases diagnosed with xanthogranulomatous inflammation of the female genital with emphasis on the etiology, clinical-pathologic features and biological behavior. Clinical, pathologic, radiologic and follow up data are reported. Results: The three cases of Xanthogranulomatous inflammation of the female genital tract are the followings: 1) one case affecting the endometrium, 2) one case affecting the fallopian tube, and 3) one case confined to the ovary. The patient's age was 37, 22 and 62 year-old, respectively. Histologic examination revealed extensive infiltration of foamy histiocytes admixed with variable amount of inflammatory cells. The later include plasma cells, lymphocytes, and occasional multinucleated giant cells. Immunohistochemistry showed positive staining for CD68, a histiocytic marker, in foamy histiocytes, CD3, a T cell marker, and CD20, a B cell marker, in the background lymphocytes. The plasma cells were polyclonal with expression of both κ and λ light chains. Conclusion: Xanthogranulomatous inflammation of the female genital tract is an unusual lesion, and clinically forms mass- like lesion in the pelvic cavity that invades the surrounding tissues, which may mimic the tumor clinically and by imaging.

Self-esteem and self-image are psychological aspects that affect sexual function. To validate a new measurement tool that correlates the concepts of self-esteem, self-image, and sexuality. A 20-question test (the self-esteem/self-image female sexuality [SESIFS] questionnaire) was created and tested on 208 women. Participants answered: Rosenberg's self-esteem scale, the female sexual quotient (FSQ), and the SESIFS questionnaire. Pearson's correlation coefficient was used to test concurrent validity of the SESIFS against Rosenberg's self-esteem scale and the FSQ. Reliability was tested using the Cronbach's alpha coefficient. The new questionnaire had a good overall reliability (Cronbach's alpha r = 0.862, p < 0.001), but the sexual domain scored lower than expected (r = 0.65). The validity was good: overall score r = 0.38, p < 0.001, self-esteem domain r = 0.32, p < 0.001, self-image domain r = 0.31, p < 0.001, sexual domain r = 0.29, p < 0.001. The SESIFS questionnaire has limitations in measuring the correlation among self-esteem, self-image, and sexuality domains. A new, revised version is being tested and will be presented in an upcoming publication.

Living close to death means an inevitable confrontation with one's own existential limitation. In this article, we argue that everyday life close to death embodies an identity work in progress. We used a narrative approach and a holistic-content reading to analyze 12 interviews conducted with three persons close to death. By illuminating the unique stories and identifying patterns among the participants' narratives, we found four themes exemplifying important aspects of the identity work related to everyday life close to death. Two of the themes, named "Inside and outside of me" and "Searching for togetherness," represented the core of the self-image and were framed by the other themes, "My place in space" and "My death and my time." Our findings elucidate the way the individual stories moved between the past, the present, and the future. This study challenges the idea that everyday life close to impending death primarily means limitations. The findings show that the search for meaning, new knowledge, and community can form a part of a conscious and ongoing identity work close to death.

How do we manage to understand a completely novel state of affairs, such as the sudden effects of an unexpected earthquake, or the arrival of a total stranger instead of the sister we were waiting for? In each case, for a moment we might be stunned, but we are able quite quickly to fit these events into our overall framework for understanding the world. However, terrified and despairing we feel, we know what earthquakes are and this event fits that schema; in the case of the stranger we know that this kind of thing happens, and that we must ask the stranger "Who are you, and where is my sister?" This paper asks about the mechanisms by which we rapidly achieve an understanding of our world, both the unexpected changes we may experience, and the ongoing comfortable familiarity we normally have with our surroundings. We attempt a solution by means of examining fundamental questions: What is it to understand something?What sorts of things do we try to understand?Is there a conscious EXPERIENCE of understanding?Does understanding involve conscious mental images?What is self-organization? I will argue that these questions revolve around the need of a living organism to take action, and that understanding anything involves knowing how we might act relative to that thing in our environment. The experience of understanding is a feeling that the action affordances of a situation are clear and available. Action (as opposed to reaction) includes imagery, particularly motor imagery, which can be used in the guidance of action. Understanding requires a conscious process involving motor imagery of action affordances, and action can be understood only in self-organizational terms. I explain how self-organization can ground the kinds of action affordance experience needed for conscious understanding. The paper concludes that our day-to-day understanding of our environment is the result of a self-organizing process.

The Dynamic Core and Global Workspace hypotheses were independently put forward to provide mechanistic and biologically plausible accounts of how brains generate conscious mental content. The Dynamic Core proposes that reentrant neural activity in the thalamocortical system gives rise to conscious experience. Global Workspace reconciles the limited capacity of momentary conscious content with the vast repertoire of long-term memory. In this paper we show the close relationship between the two hypotheses. This relationship allows for a strictly biological account of phenomenal experience and subjectivity that is consistent with mounting experimental evidence. We examine the constraints on causal analyses of consciousness and suggest that there is now sufficient evidence to consider the design and construction of a conscious artifact. PMID:21713129

The majority of scientific studies on consciousness have focused on vision, exploring the cognitive and neural mechanisms of conscious access to visual stimuli. In parallel, studies on bodily consciousness have revealed that bodily (i.e. tactile, proprioceptive, visceral, vestibular) signals are the basis for the sense of self. However, the role of bodily signals in the formation of visual consciousness is not well understood. Here we investigated how body-related visuo-tactile stimulation modulates conscious access to visual stimuli. We used a robotic platform to apply controlled tactile stimulation to the participants' back while they viewed a dot moving either in synchrony or asynchrony with the touch on their back. Critically, the dot was rendered invisible through continuous flash suppression. Manipulating the visual context by presenting the dot moving on either a body form, or a non-bodily object we show that: (i) conflict induced by synchronous visuo-tactile stimulation in a body context is associated with a delayed conscious access compared to asynchronous visuo-tactile stimulation, (ii) this effect occurs only in the context of a visual body form, and (iii) is not due to detection or response biases. The results indicate that body-related visuo-tactile conflicts impact visual consciousness by facilitating access of non-conflicting visual information to awareness, and that these are sensitive to the visual context in which they are presented, highlighting the interplay between bodily signals and visual experience.

Biochemical factors modulating female genital sexual arousal physiology.

Traish, Abdulmaged M; Botchevar, Ella; Kim, Noel N

2010-09-01

Female genital sexual arousal responses are complex neurophysiological processes consisting of central and peripheral components that occur following sexual stimulation. The peripheral responses in sexual arousal include genital vasocongestion, engorgement and lubrication resulting from a surge of vaginal and clitoral blood flow. These hemodynamic events are mediated by a host of neurotransmitters and vasoactive agents. To discuss the role of various biochemical factors modulating female genital sexual arousal responses. A comprehensive literature review was conducted using the PubMed database and citations were selected, based on topical relevance, and examined for study methodology and major findings. Data from peer-reviewed publications. Adrenergic as well as non-adrenergic non-cholinergic neurotransmitters play an important role in regulating genital physiological responses by mediating vascular and non-vascular smooth muscle contractility. Vasoactive peptides and neuropeptides also modulate genital sexual responses by regulating vascular and non-vascular smooth muscle cells and epithelial function. The endocrine milieu, particularly sex steroid hormones, is critical in the maintenance of tissue structure and function. Reduced levels of estrogens and androgen are associated with dramatic alterations in genital tissue structure, including the nerve network, as well as the response to physiological modulators. Furthermore, estrogen and androgen deficiency is associated with reduced expression of sex steroid receptors and most importantly with attenuated genital blood flow and lubrication in response to pelvic nerve stimulation. This article provides an integrated framework describing the physiological and molecular basis of various pathophysiological conditions associated with female genital sexual arousal dysfunction. © 2010 International Society for Sexual Medicine.

Context Since HSV-2 antibody tests have become commercially available, an increasing number of persons learn that they have genital herpes through serologic testing. The course of natural history of HSV-2 in asymptomatic, seropositive persons is uncertain. Objective To evaluate the virologic and clinical course of HSV genital shedding among participants with symptomatic and asymptomatic HSV-2 infection. Design, Setting and Participants Cohort of 498 immunocompetent HSV-2 seropositive persons enrolled in prospective studies of genital HSV shedding at the University of Washington Virology Research Clinic, Seattle, Washington, and Westover Heights Clinic in Portland, Oregon, between 1992 and 2008. Each participant obtained daily self-collected swabs of genital secretions for ≥ 30 days. Main Outcome Measurement The rate of viral shedding measured by quantitative real-time fluorescence polymerase chain reaction (PCR) for HSV DNA from genital swabs. Results HSV was detected on 4,753 of 23,683 days (20.1%; 95% CI, 18.3 to 22.0) in persons with symptomatic genital HSV-2 infection compared with 519 of 5,070 days (10.2%; 95% CI, 7.7 to 13.6) in persons with asymptomatic infection, p<0.001. Subclinical shedding rates were higher in persons with symptomatic infection compared with asymptomatic infection (2,708 of 20,735 days (13.1%; 95% CI, 11.5 to14.6) vs. 434 of 4,929 days (8.8%; 95% CI, 6.3 to 11.5), p<0.001. However, the amount of HSV detected during subclinical shedding episodes was similar (median 4.3 [IQR 3.1-5.6] log10 copies in the symptomatic infection group vs. 4.2 [IQR, 2.9-5.5], p=0.27 in the asymptomatic infection group). Days with lesions accounted for 2,045 of 4,753 days (43.0%; 95% CI, 39.8 to 46.5) with genital viral shedding among persons with symptomatic genital HSV-2 infection compared with 85 of 519 days (16.4%; 95% CI, 11.2 to 23.9) among persons with asymptomatic infection, p<0.001.

Mammalian external genitals show sexual dimorphism [1, 2] and can change size and shape upon sexual arousal. Genitals feature prominently in the oldest pieces of figural art [3] and phallic depictions of penises informed psychoanalytic thought about sexuality [4, 5]. Despite this longstanding interest, the neural representations of genitals are still poorly understood [6]. In somatosensory cortex specifically, many studies did not detect any cortical representation of genitals [7-9]. Studies in humans debate whether genitals are represented displaced below the foot of the cortical body map [10-12] or whether they are represented somatotopically [13-15]. We wondered what a high-resolution mapping of genital representations might tell us about the sexual differentiation of the mammalian brain. We identified genital responses in rat somatosensory cortex in a region previously assigned as arm/leg cortex. Genital responses were more common in males than in females. Despite such response dimorphism, we observed a stunning anatomical monomorphism of cortical penis and clitoris input maps revealed by cytochrome-oxidase-staining of cortical layer 4. Genital representations were somatotopic and bilaterally symmetric, and their relative size increased markedly during puberty. Size, shape, and erect posture give the cortical penis representation a phallic appearance pointing to a role in sexually aroused states. Cortical genital neurons showed unusual multi-body-part responses and sexually dimorphic receptive fields. Specifically, genital neurons were co-activated by distant body regions, which are touched during mounting in the respective sex. Genital maps indicate a deep homology of penis and clitoris representations in line with a fundamentally bi-sexual layout [16] of the vertebrate brain. Copyright © 2016 Elsevier Ltd.

Objective: Probing consciousness in noncommunicating patients is a major medical and neuroscientific challenge. While standardized and expert behavioral assessment of patients constitutes a mandatory step, this clinical evaluation stage is often difficult and doubtful, and calls for complementary measures which may overcome its inherent limitations. Several functional brain imaging methods are currently being developed within this perspective, including fMRI and cognitive event-related potentials (ERPs). We recently designed an original rule extraction ERP test that is positive only in subjects who are conscious of the long-term regularity of auditory stimuli. Methods: In the present work, we report the results of this test in a population of 22 patients who met clinical criteria for vegetative state. Results: We identified 2 patients showing this neural signature of consciousness. Interestingly, these 2 patients showed unequivocal clinical signs of consciousness within the 3 to 4 days following ERP recording. Conclusions: Taken together, these results strengthen the relevance of bedside neurophysiological tools to improve diagnosis of consciousness in noncommunicating patients. PMID:21593438

Standard clinical characterization of patients with disorders of consciousness (DOC) relies on observation of motor output and may therefore lead to the misdiagnosis of vegetative state or minimally conscious state in patients with preserved cognition. We used conventional electroencephalographic (EEG) measures to assess a cohort of DOC patients with and without functional magnetic resonance imaging (fMRI)-based evidence of command-following, and correlated the findings with standard clinical behavioral evaluation and brain metabolic activity. We enrolled 44 patients with severe brain injury. Behavioral diagnosis was established using standardized clinical assessments. Long-term EEG recordings were analyzed to determine wakeful background organization and presence of elements of sleep architecture. A subset of patients had fMRI testing of command-following using motor imagery paradigms (26 patients) and resting brain metabolism measurement using (18) fluorodeoxyglucose positron emission tomography (31 patients). All 4 patients with fMRI evidence of covert command-following consistently demonstrated well-organized EEG background during wakefulness, spindling activity during sleep, and relative preservation of cortical metabolic activity. In the entire cohort, EEG organization and overall brain metabolism showed no significant association with bedside behavioral testing, except in a few cases when EEG was severely abnormal. These findings suggest that conventional EEG is a simple strategy that complements behavioral and imaging characterization of DOC patients. Preservation of specific EEG features may be used to assess the likelihood of unrecognized cognitive abilities in severely brain-injured patients with very limited or no motor responses. © 2014 American Neurological Association.

Functional and phylogenetic analysis shows that Fgf8 is a marker of genital induction in mammals but is not required for external genital development

Summary In mammalian embryos, male and female external genitalia develop from the genital tubercle. Outgrowth of the genital tubercle is maintained by the urethral epithelium, and it has been reported that Fgf8 mediates this activity. To test directly whether Fgf8 is required for external genital development, we conditionally removed Fgf8 from the cloacal/urethral epithelium. Surprisingly, Fgf8 is not necessary for initiation, outgrowth or normal patterning of the external genitalia. In early genital tubercles, we found no redundant Fgf expression in the urethral epithelium, which contrasts with the situation in the apical ectodermal ridge (AER) of the limb. Analysis of Fgf8 pathway activity showed that four putative targets are either absent from early genital tubercles or are not regulated by Fgf8. We therefore examined the distribution of Fgf8 protein and report that, although it is present in the AER, Fgf8 is undetectable in the genital tubercle. Thus, Fgf8 is transcribed, but the signaling pathway is not activated during normal genital development. A phylogenetic survey of amniotes revealed Fgf8 expression in genital tubercles of eutherian and metatherian mammals, but not turtles or alligators, indicating that Fgf8 expression is neither a required nor a conserved feature of amniote external genital development. The results indicate that Fgf8 expression is an early readout of the genital initiation signal rather than the signal itself. We propose that induction of external genitalia involves an epithelial-epithelial interaction at the cloacal membrane, and suggest that the cloacal ectoderm may be the source of the genital initiation signal.

Occupational Consciousness.

PubMed

Ramugondo, Elelwani L

2015-10-02

Occupational consciousness refers to ongoing awareness of the dynamics of hegemony and recognition that dominant practices are sustained through what people do every day, with implications for personal and collective health. The emergence of the construct in post-apartheid South Africa signifies the country's ongoing struggle with negotiating long-standing dynamics of power that were laid down during colonialism, and maintained under black majority rule. Consciousness, a key component of the new terminology, is framed from post-colonial perspectives - notably work by Biko and Fanon - and grounded in the philosophy of liberation, in order to draw attention to continuing unequal intersubjective relations that play out through human occupation. The paper also draws important links between occupational consciousness and other related constructs, namely occupational possibilities, occupational choice, occupational apartheid, and collective occupation. The use of the term 'consciousness' in sociology, with related or different meanings, is also explored. Occupational consciousness is then advanced as a critical notion that frames everyday doing as a potentially liberating response to oppressive social structures. This paper advances theorizing as a scholarly practice in occupational science, and could potentially expand inter or transdisciplinary work for critical conceptualizations of human occupation.

Psychological factors predicting the distress to female persistent genital arousal symptoms.

2015-01-01

Symptoms of persistent genital arousal are expected to negatively affect women's sexual and emotional well-being. However, not all women who experience persistent genital arousal complain about their genital condition. Against this background, this study aimed to evaluate psychological predictors of the distress associated with persistent genital arousal symptoms, as well as psychological moderators influencing the conditions under which persistent genital arousal causes distress. A total of 117 women reporting symptoms of persistent genital arousal answered to online questionnaires measuring personality traits, sexual beliefs, and dyadic adjustment. Women have also completed a checklist measuring the frequency/severity of persistent genital arousal symptoms and the distress/impairment caused by these symptoms. Results showed that neuroticism, (low) openness, sexual conservatism, and (low) dyadic adjustment significantly predicted distress associated with genital symptoms. Furthermore, sexual conservatism was found to moderate the relation between the symptoms' severity and the distress associated with those symptoms. Overall, sexual conservatism seems to be a key differentiator factor, influencing the psychological conditions under which women may report higher levels of distress caused by persistent genital arousal. Because such findings focus on the distress to genital arousal symptoms rather than on persistent genital arousal disorder as a clinical entity, the results under consideration may or may not characterize women formally assigned to the persistent genital arousal disorder label.

INTRODUCTION Self-esteem and self-image are psychological aspects that affect sexual function. AIMS To validate a new measurement tool that correlates the concepts of self-esteem, self-image, and sexuality. METHODS A 20-question test (the self-esteem/self-image female sexuality [SESIFS] questionnaire) was created and tested on 208 women. Participants answered: Rosenberg’s self-esteem scale, the female sexual quotient (FSQ), and the SESIFS questionnaire. Pearson’s correlation coefficient was used to test concurrent validity of the SESIFS against Rosenberg’s self-esteem scale and the FSQ. Reliability was tested using the Cronbach’s alpha coefficient. RESULT The new questionnaire had a good overall reliability (Cronbach’s alpha r = 0.862, p < 0.001), but the sexual domain scored lower than expected (r = 0.65). The validity was good: overall score r = 0.38, p < 0.001, self-esteem domain r = 0.32, p < 0.001, self-image domain r = 0.31, p < 0.001, sexual domain r = 0.29, p < 0.001. CONCLUSIONS The SESIFS questionnaire has limitations in measuring the correlation among self-esteem, self-image, and sexuality domains. A new, revised version is being tested and will be presented in an upcoming publication. PMID:25574149

Improving the clinical assessment of consciousness with advances in electrophysiological and neuroimaging techniques

PubMed Central

2010-01-01

In clinical neurology, a comprehensive understanding of consciousness has been regarded as an abstract concept - best left to philosophers. However, times are changing and the need to clinically assess consciousness is increasingly becoming a real-world, practical challenge. Current methods for evaluating altered levels of consciousness are highly reliant on either behavioural measures or anatomical imaging. While these methods have some utility, estimates of misdiagnosis are worrisome (as high as 43%) - clearly this is a major clinical problem. The solution must involve objective, physiologically based measures that do not rely on behaviour. This paper reviews recent advances in physiologically based measures that enable better evaluation of consciousness states (coma, vegetative state, minimally conscious state, and locked in syndrome). Based on the evidence to-date, electroencephalographic and neuroimaging based assessments of consciousness provide valuable information for evaluation of residual function, formation of differential diagnoses, and estimation of prognosis.

Comparison of Brain Activity Correlating with Self-Report versus Narrative Attachment Measures during Conscious Appraisal of an Attachment Figure.

2016-01-01

The Adult Attachment Interview (AAI) has been the gold standard of attachment assessment, but requires special training. The Relationship Scales Questionnaire (RSQ) is a widely used self-report measure. We investigate how each correlates with brain activity during appraisal of subjects' mothers. Twenty-eight women were scored on the AAI, RSQ, and mood measures. During functional magnetic resonance imaging, subjects viewed their mothers in neutral-, valence-, and salience-rating conditions. We identified regions where contrasts in brain activity between appraisal and neutral viewing conditions correlated with each measure of attachment after covarying for mood. AAI and RSQ measures were then compared in terms of the extent to which regions of correlating brain activity overlapped with "default mode network" (DMN) vs. executive frontal network (EFN) masks and cortical vs. subcortical masks. Additionally, interactions with mood were examined. Salience and valence processing associated with increased thalamo-striatal, posterior cingulate, and visual cortex activity. Salience processing decreased PFC activity, whereas valence processing increased left insula activity. Activity correlating with AAI vs. RSQ measures demonstrated significantly more DMN and subcortical involvement. Interactions with mood were observed in the middle temporal gyrus and precuneus for both measures. The AAI appears to disproportionately correlate with conscious appraisal associated activity in DMN and subcortical structures, while the RSQ appears to tap EFN structures more extensively. Thus, the AAI may assess more interoceptive, 'core-self'-related processes, while the RSQ captures higher-order cognitions involved in attachment. Shared interaction effects between mood and AAI and RSQ-measures may suggest that processes tapped by each belong to a common system.

Pain, dissociation and subliminal self-representations.

PubMed

Bob, Petr

2008-03-01

According to recent evidence, neurophysiological processes coupled to pain are closely related to the mechanisms of consciousness. This evidence is in accordance with findings that changes in states of consciousness during hypnosis or traumatic dissociation strongly affect conscious perception and experience of pain, and markedly influence brain functions. Past research indicates that painful experience may induce dissociated state and information about the experience may be stored or processed unconsciously. Reported findings suggest common neurophysiological mechanisms of pain and dissociation and point to a hypothesis of dissociation as a defense mechanism against psychological and physical pain that substantially influences functions of consciousness. The hypothesis is also supported by findings that information can be represented in the mind/brain without the subject's awareness. The findings of unconsciously present information suggest possible binding between conscious contents and self-functions that constitute self-representational dimensions of consciousness. The self-representation means that certain inner states of own body are interpreted as mental and somatic identity, while other bodily signals, currently not accessible to the dominant interpreter's access are dissociated and may be defined as subliminal self-representations. In conclusion, the neurophysiological aspects of consciousness and its integrative role in the therapy of painful traumatic memories are discussed.

Chlamydial variants differ in ability to ascend the genital tract in the guinea pig model of chlamydial genital infection.

2015-08-01

An important question in the study of chlamydial genital tract disease is why some women develop severe upper tract disease while others have mild or even "silent" infections with or without pathology. Animal studies suggest that the pathological outcome of an infection is dependent upon both the composition of the infecting chlamydial population and the genotype of the host, along with host physiological effects, such as the cyclical production of reproductive hormones and even the size of the infecting inoculum or the number of repeated infections. In this study, we compared two variants of Chlamydia caviae, contrasting in virulence, with respect to their abilities to ascend the guinea pig genital tract. We then determined the effect of combining the two variants on the course of infection and on the bacterial loads of the two variants in the genital tract. Although the variants individually had similar infection kinetics in the cervix, SP6, the virulent variant, could be isolated from the oviducts more often and in greater numbers than the attenuated variant, AZ2. SP6 also elicited higher levels of interleukin 8 (IL-8) in the lower genital tract and increased leukocyte infiltration in the cervix and uterus compared to AZ2. When the two variants were combined in a mixed infection, SP6 outcompeted AZ2 in the lower genital tract; however, AZ2 was able to ascend the genital tract as readily as SP6. These data suggest that the ability of SP6 to elicit an inflammatory response in the lower genital tract facilitates the spread of both variants to the oviducts.

The persistent or recurrent difficulties of the woman to allow vaginal entry of a penis, a finger, and/or any object, despite the woman's expressed wish to do so" is vaginismus. Early traumatic sexual experiences (e.g. sexual abuse), religious orthodoxy, low self-esteem and body image, negative attitudes about sexuality, lack of knowledge about sex and fear responses are some of the traditional etiological correlates of vaginismus. Vaginismus is largely a diagnosis of exclusion. An interview is crucial in differentiating the causes of this disease and it should involve the following key questions: -whether the contraction of the vaginal muscles was recorded from the first sexual contact and still remains a need for sexual satisfaction is achieved without relations vaginal or -symptom occurs for some time and what circumstances it bound or -contraction of the muscles is independent of the will, reflex and is at the very idea of sexual intercourse, and -that the contraction of the vaginal muscles occurs when you try to enter the member into the vagina which is very painful. The physical, gynecological and sexuological examinations exclude local causes of the disease. The mainstay of treatment in the majority of cases is psychosexual support. The cause of organic vaginismus is congenital malformation of the genital tract. It results from abnormal development of genital paramesonephric (Müllerian) ducts and the urogenital sinus, which are structures involved in the process of oviduct, uterus, and vagina organogenesis. This has strong implications in the practices of gynecology and sexuology in general, not only in adolescent gynecology and sexuology. Vaginismus with congenital malformation is an important problem in these fields.

Impaired Consciousness in Epilepsy

Blumenfeld, Hal

2013-01-01

Consciousness is essential to normal human life. In epileptic seizures consciousness is often transiently lost making it impossible for the individual to experience or respond. This has huge consequences for safety, productivity, emotional health and quality of life. To prevent impaired consciousness in epilepsy it is necessary to understand the mechanisms leading to brain dysfunction during seizures. Normally the “consciousness system”—a specialized set of cortical-subcortical structures—maintains alertness, attention and awareness. Recent advances in neuroimaging, electrophysiology and prospective behavioral testing have shed new light on how epileptic seizures disrupt the consciousness system. Diverse seizure types including absence, generalized tonic-clonic and complex partial seizures converge on the same set of anatomical structures through different mechanisms to disrupt consciousness. Understanding these mechanisms may lead to improved treatment strategies to prevent impaired consciousness and improve quality of life in people with epilepsy. PMID:22898735

Female genital mutilation in Djibouti.

2012-12-01

The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C.

Management of external genital warts.

Genital warts affect 1% of the sexually active U.S. population and are commonly seen in primary care. Human papillomavirus types 6 and 11 are responsible for most genital warts. Warts vary from small, flat-topped papules to large, cauliflower-like lesions on the anogenital mucosa and surrounding skin. Diagnosis is clinical, but atypical lesions should be confirmed by histology. Treatments may be applied by patients, or by a clinician in the office. Patient-applied treatments include topical imiquimod, podofilox, and sinecatechins, whereas clinician-applied treatments include podophyllin, bichloroacetic acid, and trichloroacetic acid. Surgical treatments include excision, cryotherapy, and electrosurgery. The quadrivalent human papillomavirus vaccine is active against virus subtypes that cause genital warts in men and women. Additionally, male circumcision may be effective in decreasing the transmission of human immunodeficiency virus, human papillomavirus, and herpes simplex virus.

A half billion people have genital herpes infections worldwide. Approximately one-fifth of American women between ages 14 and 49 are HSV-2 seropositive. The development of an effective genital herpes vaccine is a global health necessity based on the mental anguish genital herpes causes for some individuals, the fact that pregnant women with genital herpes risk transmitting infection to their newborn children, and the observation that HSV-2 infection is associated with a 3-fold to 4-fold increased probability of HIV acquisition. We review the strengths and limitations of preclinical animal models used to assess genital herpes vaccine candidates and the goals of prophylactic and therapeutic vaccines. We also discuss the current pipeline of vaccine candidates and lessons learned from past clinical trials that serve as a stimulus for new strategies, study designs and endpoint determinations.

Objective. To determine forms of female genital mutilation (FGM), assess consistency between self-reported and observed FGM status, and assess the accuracy of Demographic and Health Surveys (DHS) FGM questions in Sierra Leone. Methods. This cross-sectional study, conducted between October 2010 and April 2012, enrolled 558 females aged 12–47 from eleven antenatal clinics in northeast Sierra Leone. Data on demography, FGM status, and self-reported anatomical descriptions were collected. Genital inspection confirmed the occurrence and extent of cutting. Results. All participants reported FGM status; 4 refused genital inspection. Using the WHO classification of FGM, 31.7% had type Ib; 64.1% type IIb; and 4.2% type IIc. There was a high level of agreement between reported and observed FGM prevalence (81.2% and 81.4%, resp.). There was no correlation between DHS FGM responses and anatomic extent of cutting, as 2.7% reported pricking; 87.1% flesh removal; and 1.1% that genitalia was sewn closed. Conclusion. Types I and II are the main forms of FGM, with labia majora alterations in almost 5% of cases. Self-reports on FGM status could serve as a proxy measurement for FGM prevalence but not for FGM type. The DHS FGM questions are inaccurate for determining cutting extent. PMID:24204384

Functional magnetic resonance imaging (fMRI) is a technique with significant potential to advance our understanding of multiple brain systems. However, when human subjects undergo fMRI studies they are typically conscious whereas pre-clinical fMRI studies typically utilize anesthesia, which complicates comparisons across studies. Therefore, we have developed an apparatus suitable for imaging conscious rhesus monkeys. In order to minimize subject stress and spatial motion, each subject was acclimated to the necessary procedures over several months. The effectiveness of this process was then evaluated, in fully trained subjects, by quantifying objective physiological measures. These physiological metrics were stable both within and across sessions and did not differ from when these same subjects were immobilized using standard primate handling procedures. Subject motion and blood oxygenation level dependent (BOLD) fMRI measurements were then evaluated by scanning subjects under three different conditions: the absence of stimulation, presentation of a visual stimulus, or administration of intravenous (i.v.) cocaine (0.3mg/kg). Spatial motion differed neither by condition nor along the three principal axes. In addition, maximum translational and rotational motion never exceeded one half of the voxel size (0.75 mm) or 1.5 degrees, respectively. Furthermore, the localization of changes in blood oxygenation closely matched those reported in previous studies using similar stimuli. These findings document the feasibility of fMRI data collection in conscious rhesus monkeys using these procedures and allow for the further study of the neural effects of psychoactive drugs.

Nano-imaging enabled via self-assembly

SUMMARY Imaging object details with length scales below approximately 200 nm has been historically difficult for conventional microscope objective lenses because of their inability to resolve features smaller than one-half the optical wavelength. Here we review some of the recent approaches to surpass this limit by harnessing self-assembly as a fabrication mechanism. Self-assembly can be used to form individual nano- and micro-lenses, as well as to form extended arrays of such lenses. These lenses have been shown to enable imaging with resolutions as small as 50 nm half-pitch using visible light, which is well below the Abbe diffraction limit. Furthermore, self-assembled nano-lenses can be used to boost contrast and signal levels from small nano-particles, enabling them to be detected relative to background noise. Finally, alternative nano-imaging applications of self-assembly are discussed, including three-dimensional imaging, enhanced coupling from light-emitting diodes, and the fabrication of contrast agents such as quantum dots and nanoparticles.

Chlamydia muridarum is known to colonize in the gastrointestinal tract for long periods of time, which has been hypothesized to serve as a reservoir for spreading to the genital tract. To test this hypothesis, a luciferase-expressing C. muridarum was used to establish a long-lasting infection in the mouse gastrointestinal tract following either intragastric or intrarectal inoculations. In vivo imaging revealed significant bioluminescent signals mainly in the mouse abdominal area throughout the experiments. Ex vivo imaging localized the signals to the mouse gastrointestinal tract, which was confirmed by monitoring the C. muridarum organisms in the mouse organs/tissues. Despite the long-lasting colonization in the gastrointestinal tract and active shedding of infectious organisms in the rectal swabs, the organisms did not cause any significant infection or pathology in the genital tract throughout the experiments, which was reproduced in multiple strains of mice and with an increased inoculation dose to the gastrointestinal tract. The above observations have demonstrated that the long-lasting C. muridarum organisms from the gastrointestinal tract are inefficient in auto-inoculating the genital tract, suggesting that the gastrointestinal tract Chlamydia may utilize an indirect mechanism to affect its pathogenicity in the genital tract.

What aspects of neuronal activity distinguish the conscious from the unconscious brain? This has been a subject of intense interest and debate since the early days of neurophysiology. However, as any practicing anesthesiologist can attest, it is currently not possible to reliably distinguish a conscious state from an unconscious one on the basis of brain activity. Here we approach this problem from the perspective of dynamical systems theory. We argue that the brain, as a dynamical system, is self-regulated at the boundary between stable and unstable regimes, allowing it in particular to maintain high susceptibility to stimuli. To test this hypothesis, we performed stability analysis of high-density electrocorticography recordings covering an entire cerebral hemisphere in monkeys during reversible loss of consciousness. We show that, during loss of consciousness, the number of eigenmodes at the edge of instability decreases smoothly, independently of the type of anesthetic and specific features of brain activity. The eigenmodes drift back toward the unstable line during recovery of consciousness. Furthermore, we show that stability is an emergent phenomenon dependent on the correlations among activity in different cortical regions rather than signals taken in isolation. These findings support the conclusion that dynamics at the edge of instability are essential for maintaining consciousness and provide a novel and principled measure that distinguishes between the conscious and the unconscious brain. SIGNIFICANCE STATEMENT What distinguishes brain activity during consciousness from that observed during unconsciousness? Answering this question has proven difficult because neither consciousness nor lack thereof have universal signatures in terms of most specific features of brain activity. For instance, different anesthetics induce different patterns of brain activity. We demonstrate that loss of consciousness is universally and reliably associated with stabilization

Why patients mutilate themselves.

Favazza, A R

1989-02-01

Self-mutilation, the deliberate destruction or alteration of body tissue without conscious suicidal intent, occurs in a variety of psychiatric disorders. Major self-mutilation includes eye enucleation and amputation of limbs or genitals. Minor self-mutilation includes self-cutting and self-hitting. The author examines patients' explanations for self-mutilation which frequently focus on religions or sexual themes, and discusses scientific explanations that draw on biological, psychological, social, and cultural theories. Although no one approach adequately solves the riddle of such behaviors, habitual self-mutilation may best be thought of as a purposeful, if morbid, act of self-help.

ABSTRACT An estimated 417 million people worldwide ages 15 to 49 are infected with herpes simplex virus type 2 (HSV-2), the most common cause of genital ulcer disease. Some individuals experience frequent recurrences of genital lesions, while others only have subclinical infection, yet all risk transmitting infection to their intimate partners. A vaccine was developed that prevents shingles, which is a recurrent infection caused by varicella-zoster virus (VZV), a closely related member of the Herpesviridae family. The success of the VZV vaccine has stimulated renewed interest in a therapeutic vaccine for genital herpes. We have been evaluating a trivalent subunit antigen vaccine for prevention of genital herpes. Here, we assess the trivalent vaccine as immunotherapy in guinea pigs that were previously infected intravaginally with HSV-2. The trivalent vaccine contains HSV-2 glycoproteins C, D, and E (gC2, gD2, gE2) subunit antigens administered with CpG and alum as adjuvants. We previously demonstrated that antibodies to gD2 neutralize the virus while antibodies to gC2 and gE2 block their immune evasion activities, including evading complement attack and inhibiting activities mediated by the IgG Fc domain, respectively. Here, we demonstrate that the trivalent vaccine significantly boosts ELISA titers and neutralizing antibody titers. The trivalent vaccine reduces the frequency of recurrent genital lesions and vaginal shedding of HSV-2 DNA by approximately 50% and almost totally eliminates vaginal shedding of replication-competent virus, suggesting that the trivalent vaccine is a worthy candidate for immunotherapy of genital herpes.

Previous studies implicated potential value of mismatch negativity (MMN) in predicting recovery of consciousness in patients with disorders of consciousness (DOC). We have adopted a novel MMN evoked by subject's own name (SON), a self-referential stimulus thought to be powerful in evoking residual brain activity, and examined the correlation between the MMN and recovery of consciousness in patients with chronic (>1 month) DOC. Twelve patients and 12 age-matched healthy controls were investigated. The patients were diagnosed as coma (n=4), vegetative state (VS, n=6), and minimally conscious state (MCS, n=2), mainly based on the JFK Coma Recovery Scale-Revised. The SON-evoked MMN (SON-MMN) was present in seven patients. Critically, the presence of SON-MMN was significantly correlated with recovery of consciousness. While four of the five patients (three VS and two coma) showing SON-MMN changed to MCS 3 months later, the rest of the patients (three VS and two coma) without SON-MMN failed to show any clinical improvement. Our study thus illustrates that the subject's own name is effective in evoking MMN in patients with DOC, and that SON-MMN has potential prognostic values in predicting recovery of consciousness.

This study examines the effect of thin-body media images on mood, self-esteem, and self-image ratings of restrained and unrestrained eaters. A secondary purpose was to examine whether these effects were influenced by exposure duration. Under the guise of a perception study, participants were exposed to thin-body or control advertisements (e.g., perfume bottles) for either 7 or 150 ms and then completed a questionnaire packet. Restrained eaters reported more favorable self-image and social self-esteem (but not appearance self-esteem) scores after exposure to thin-body images than after exposure to control advertisements. The self-image and social self-esteem scores of unrestrained eaters were unaffected by advertisement type, but their appearance self-esteem scores were lower after exposure to thin-body advertisements. No differences were found for mood ratings and total self-esteem. We discuss restraint status as a moderator of the effects of thin-body images on women's body image.

Genital herpes is an incurable, chronic disease that affects millions of people worldwide. Not only does genital herpes cause painful, recurrent symptoms, it is also a significant risk factor for the acquisition of other sexually transmitted infections such as HIV-1. Antiviral drugs are used to treat herpes simplex virus (HSV) infection, but they cannot stop viral shedding and transmission. Thus, developing a vaccine that can prevent or clear infection will be crucial in limiting the spread of disease. In this review we outline recent studies that improve our understanding of host responses against HSV infection, discuss past clinical vaccine trials, and highlight new strategies for vaccine design against genital herpes.

Narrating consciousness: language, media and embodiment.

Hayles, N Katherine; Pulizzi, James J

2010-01-01

Although there has long been a division in studies of consciousness between a focus on neuronal processes or conversely an emphasis on the ruminations of a conscious self, the long-standing split between mechanism and meaning within the brain was mirrored by a split without, between information as a technical term and the meanings that messages are commonly thought to convey. How to heal this breach has posed formidable problems to researchers. Working through the history of cybernetics, one of the historical sites where Claude Shannon's information theory quickly became received doctrine, we argue that the cybernetic program as it developed through second-order cybernetics and autopoietic theory remains incomplete. In this article, we return to fundamental questions about pattern and noise, context and meaning, to forge connections between consciousness, narrative and media. The thrust of our project is to reintroduce context and narrative as crucial factors in the processes of meaning-making. The project proceeds along two fronts: advancing a theoretical framework within which context plays its property central role; and demonstrating the importance of context by analyzing two fictions, Stanislaw Lem's "His Master's Voice" and Joseph McElroy's "Plus," in which context has been deformed by being wrenched away from normal human environments, with radical consequences for processes of meaning-making.

Global environmental challenges require changes in both the production and the consumption of goods. In this paper we analyse how consumers perceive the high environmental burden of meat. We analysed consumer environmental consciousness, including problem awareness and a support to action dimensions, latter including perceived self-efficacy as well as solutions to problems. The solutions were positioned on a continuum from increasing the efficiency of production to discussing sufficiency levels in consumption practices (techno-optimism, local meat, organic meat and meat reduction, respectively). We used a statistically representative survey sample (n = 1890) from the population of Finland and cluster analysis to explore differences among consumers. The analysis revealed that most Finns seem to be rather unsure of the study topic. At the same time they tend to have a comparably high level of self-efficacy (55 per cent of respondents) and endorsement of particularly local meat solution type (55%), followed by organic meat (35%), meat reduction (25%) and techno-optimism (15%), though the neutral stand was the most common one across the data. We also identified six consumer groups that reveal not only a high number of Highly unsure consumers (40%), but also some Rather conscious (20%) and a relatively small number of Highly conscious (8%). In addition, there were also easily observable groups of Careless conscious (14%), Rather unsure (9%) and Resistant (8%). The results highlight the need for a multitude of political actions to guide meat consumption, as there are groups that may benefit from practical tools for making dietary changes as well as groups in need for more comprehensive selection of measures, including environmental information.

To conduct an empirical analysis of self-referred whole-body computed tomography (CT) and develop a profile of the geographic and demographic distribution of centers, types of services and modalities, costs, and procedures for reporting results. An analysis was conducted of Web sites for imaging centers accepting self-referred patients identified by two widely used Internet search engines with large indexes. These Web sites were analyzed for geographic location, type of screening center, services, costs, and procedures for managing imaging results. Demographic data were extrapolated for analysis on the basis of center location. Descriptive statistics, such as frequencies, means, SDs, ranges, and CIs, were generated to describe the characteristics of the samples. Data were compared with national norms by using a distribution-free method for calculating a 95% CI (P <.05) for the median. Eighty-eight centers identified with the search methods were widely distributed across the United States, with a concentration on both coasts. Demographic analysis further situated them in areas of the country characterized by a population that consisted largely of European Americans (P <.05) and individuals of higher education (P <.05) and socioeconomic status (P <.05). Forty-seven centers offered whole-body screening; heart and lung examinations were most frequently offered. Procedures for reporting results were highly variable. The geographic distribution of the centers suggests target populations of educated health-conscious consumers who can assume high out-of-pocket costs. Guidelines developed from within the profession and further research are needed to ensure that benefits of these services outweigh risks to individuals and the health care system.

Women’s perspectives of female genital cutting: Q-methodology

PubMed Central

2014-01-01

Background Understanding women’s perspectives of female genital cutting is particularly critical for understanding the roots of the problem and enhancing effectiveness of any prevention program. Very limited research has examined how people in Iraqi Kurdistan Region think about this practice. This study aimed to explore the perspectives of women of female genital cutting with the aim of uncovering discrepancies and commonalities between women of different socio-educational groups. Methods An explorative study using Q-methodology was conducted with 29 women from different educational and socio-economic statuses in Erbil, the main city of the Iraqi Kurdistan Region. Participants were asked to rank-order a set of 39 statements about different aspects of female genital cutting into a distribution on a scale of nine from “disagree most” to “agree most”. By-person factor analysis was performed with factors or latent viewpoints extracted through centroid method and varimax rotation. Results A four-factor solution and one consensus perspective provided the best conceptual fit for the women’s perspectives about female genital cutting. Factor 1, entitled “positive cultural tradition”, centers on recognizing female genital cutting as a positive cultural aspect and an essential part of the Kurdish culture. Factor 2, “active opponents”, positions around actively opposing the practice of female genital cutting and considering the practice a violation of human rights. Factor 3, “role of law”, stresses the importance of developing and enforcing law for combating female genital cutting. Factor 4, “health concerns and passive opposition”, represents the perspectives of recognizing the importance of health concerns resulting from female genital cutting and opposition of the practice but not in an active manner. A consensus perspective, “marital role”, centers primarily on lack of effect of female genital cutting on women’s marital role. Conclusions
