Science of the Brain as a Gateway to Understanding Play: An Interview with Jaak Panksepp
ERIC Educational Resources Information Center
American Journal of Play, 2010
2010-01-01
Jaak Panksepp, known best for his work on animal emotions and coining the term "affective neuroscience," investigates the primary processes of brain and mind that enable and drive emotion. As an undergraduate, he briefly considered a career in electrical engineering but turned instead to psychology, which led to a 1969 University of…

Theory of drives and emotions - from Sigmund Freud to Jaak Panksepp.
Żechowski, Cezary
2017-12-30
The article discusses the development of psychoanalytic theory in the direction of broadening the reflection on their own based on data derived from empirical studies other than clinical case study. Particularly noteworthy is the convergence that followed between neuroscience and psychoanalysis and the rise of the so-called neuropsychoanalysis. Consequently, this led to eject empirical hypotheses and begin research on defense mechanisms, self, memory, dreams, empathy, dynamic unconscious and emotional-motivational processes (theory of drives). Currently neuropsychoanalysis constituted itself as a discipline contained in itself three separate areas: the psychodynamic neuroscience, clinical neuropsychoanalysis and theory building. The article introduces the theory of Jaak Panksepp emotional systems as an example of anintegrated neurobiology of affect, behavioral biology, evolutionary psychology and psychoanalysis. The theory of emotional systems includes the description of the SEEKING system representing basic motivational system of the organism. Apart from a new perspective on the theory of drives described by Sigmund Freud, it offers the possibility to take into account the emotional and motivational systems within the understanding of mental disorders such as depression, addiction and psychosis, which is the core of psychoanalytic thinking.

Peptides of the adipokinetic hormone (AKH)/red pigment-concentrating hormone (RPCH) family were isolated and sequenced from the retrocerebral corpora cardiaca of four kissing bugs which are all vectors of the protozoan Trypanosoma cruzi responsible for Chagas' disease. The sequence of three novel AKHs were deduced from the multiple MS(N) electrospray mass data: the octapeptide pGlu-Leu-Thr-Phe-Ser-Thr-Asp-Trp amide (denoted Rhopr-AKH) in Rhodnius prolixus and Panstrongylus megistus, the nonapeptide pGlu-Leu-Thr-Phe-Thr-Pro-Asn-Trp-Gly amide (denoted Triin-AKH) in Triatoma infestans and the decapeptide pGlu-Leu-Thr-Phe-Ser-Asp-Gly-Trp-Gly-Asn amide (denoted Dipma-AKH) in Dipetalogaster maxima. The sequences were confirmed by identical behavior of natural and synthetic forms in reversed-phase HPLC and by CID-MS mass spectra. Conspecific injections of a dose of 10 pmol of the respective synthetic peptides resulted in a small but significant increase of the lipid concentration in the hemolymph. These experiments suggest that AKHs in kissing bugs act to regulate lipid metabolism, possibly during dispersal flights which is one of the mechanisms whereby the insects reach new outbreak areas.

The knowledge about the activity of polyacetylenes was extended by their new acetylcholinesterase inhibition and antibacterial activity against plant pathogenic bacteria. For this discovery, an utmost streamlined workflow, which we consider to be of high potential in the field of natural product or superfood search was developed. It demonstrates the combined power of biological, biochemical and chemical fingerprints. Bioactive components of tansy (Tanacetum vulgare L.) root extract were profiled and identified by high-performance thin-layer chromatography hyphenated with in situ effect-directed analysis, chemical derivatizations and high-resolution mass spectrometry (HPTLC-UV/Vis/FLD-EDA-HRMS). The effect-directed profiling was performed using four bacterial bioassays including two plant pathogens, an antioxidant assay and acetyl- and butyrylcholinesterase inhibitory assays. The chromatographic, spectral and powerful mass spectrometric study of zones that exerted substantial antibacterial and/or antioxidant and/or acetylcholinesterase inhibitory effects allowed these multi-potent zones to be identified as polyacetylenes. Five polyacetylene compounds were assigned to be 2-non-1-ene-3,5,7-triynyl-3-vinyl-oxirane, 2-(2,4-hexadiynylidene)-3,4-epoxy-1,6-dioxaspiro[4.5]decane, trans- and cis-2-(2,4-hexadiynylidene)-1,6-dioxaspiro[4.5]dec-3-ene and tetradeca-2,4,6-triine-8-en-12-one. This study clearly showed the advantage of the combined use of different ionization sources, i.e. electrospray ionization via an elution-head based interface and also the Direct Analysis in Real Time interface, for HRMS analysis of compounds from the same class with very similar chromatographic behavior and polarity.

What Affective Neuroscience Means for Science Of Consciousness
Almada, Leonardo Ferreira; Pereira, Alfredo; Carrara-Augustenborg, Claudia
2013-01-01
The field of affective neuroscience has emerged from the efforts of Jaak Panksepp in the 1990s and reinforced by the work of, among others, Joseph LeDoux in the 2000s. It is based on the ideas that affective processes are supported by brain structures that appeared earlier in the phylogenetic scale (as the periaqueductal gray area), they run in parallel with cognitive processes, and can influence behaviour independently of cognitive judgements. This kind of approach contrasts with the hegemonic concept of conscious processing in cognitive neurosciences, which is based on the identification of brain circuits responsible for the processing of (cognitive) representations. Within cognitive neurosciences, the frontal lobes are assigned the role of coordinators in maintaining affective states and their emotional expressions under cognitive control. An intermediary view is the Damasio-Bechara Somatic Marker model, which puts cognition under partial somatic-affective control. We present here our efforts to make a synthesis of these views, by proposing the existence of two interacting brain circuits; the first one in charge of cognitive processes and the second mediating feelings about cognitive contents. The coupling of the two circuits promotes an endogenous feedback that supports conscious processes. Within this framework, we present the defence that detailed study of both affective and cognitive processes, their interactions, as well of their respective brain networks, is necessary for a science of consciousness.

Critical notes on the neuro-evolutionary archaeology of affective systems.
Barratt, Barnaby B
2015-04-01
If progress is to be made in resolving the debate over the relevance of neuroscientific findings to psychoanalysis, a clearer distinction must be established between a narrow definition of psychoanalysis as "praxis" (the science of lived experience and its conflicts or contradictions) and a definition that focuses on metapsychology as objectivistic theory-building. The investigations of Jaak Panksepp on the "neuro-archaeology" of affective systems are reviewed as an example of how findings in neuroscience cannot be legitimately extrapolated to offer conclusions about the domain of lived experience. In this context, Freud's shifting standpoint is reviewed and, following the writings of Jean Laplanche, the significance of Freud's distinction between "drives" or libidinality, as acquired through experience, and "instincts," which are purely biological, is emphasized. It is argued that there is an unavoidable component of myth-making in any consideration of the connection between neural circuitry and the domain of psychic representations. Freud's need for a notion of drive or energy, which is required to understand the findings of free-associative method, is admittedly mythematic, but it implies a major challenge to extant philosophical doctrines of the "mind/body" question (emergentism, double-aspect monism, and neutral monism). Thus, whereas psychoanalysis as praxis is, in Freud's words, "free to follow its own requirements," the claims of metapsychology are not so unrestrained. Further debate is required on the irrelevance of a revised objectivistic theory of the "mental apparatus" to the venture of healing the fracturing of our lived experience.

According to Jaak Panksepp's Affective Neuroscience Theory and the derived self-report measure, the Affective Neuroscience Personality Scales (ANPS), differences in the responsiveness of primary emotional systems form the basis of human personality. In order to investigate neuronal correlates of personality, the underlying neuronal circuits of the primary emotional systems were analyzed in the present fMRI-study by associating the ANPS to functional connectivity in the resting brain. N=120 healthy participants were invited for the present study. The results were reinvestigated in an independent, smaller sample of N=52 participants. A seed-based whole brain approach was conducted with seed-regions bilaterally in the basolateral and superficial amygdalae. The selection of seed-regions was based on meta-analytic data on affective processing and the Juelich histological atlas. Multiple regression analyses on the functional connectivity maps revealed associations with the SADNESS-scale in both samples. Functional resting-state connectivity between the left basolateral amygdala and a cluster in the postcentral gyrus, and between the right basolateral amygdala and clusters in the superior parietal lobe and subgyral in the parietal lobe was associated with SADNESS. No other ANPS-scale revealed replicable results. The present findings give first insights into the neuronal basis of the SADNESS-scale of the ANPS and support the idea of underlying neuronal circuits. In combination with previous research on genetic associations of the ANPS functional resting-state connectivity is discussed as a possible endophenotype of personality. Copyright © 2016 Elsevier Inc.
