Auditory metre perception refers to the ability to extract a temporally regular pulse and an underlying hierarchical structure of perceptual accents from a sequence of tones. Pulse perception is widely present in humans, and can be measured by the temporal expectancy for prospective tones, which listeners generate when presented with a metrical rhythm. We tested whether musical expertise leads to ...

Abstract�Floating-gate (FG) transistors are useful for precisely programming a large array of current sources. Present FG programming techniques require disconnection of the transistor from the rest of its circuit while it is being programmed. We present a new method of programming FG transistors that does not require this disconnection. In this indirect programming method, ...

Agreement is one of the main devices used by languages to signal grammatical relations.

This study investigates the electrical brain activity correlates of the automatic detection of suprasegmental and local speech cues by using a passive oddball paradigm, in which the standard Hungarian word 'ban�n' ('banana' in English) was contrasted with two deviants: a voiceless phoneme deviant ('pan�n'), and a stress deviant, where the stress was on the second syllable, instead of the ...

Most natural sounds are composed of a mixture of frequencies, which activate separate neurons in the tonotopic auditory cortex. Nevertheless, we perceive this mixture as an integrated sound with unique acoustic properties. We used the Mismatch Negativity (MMN), a marker of auditory change detection, to determine whether individual harmonics are represented ...

This study used the event-related brain potential mismatch negativity (MMN) to investigate preconscious discrimination of harmonically rich tones (differing in duration) and consonant-vowel syllables (differing in the initial consonant) in aphasia. Eighteen Norwegian aphasic patients, examined on average 3 months after brain injury, were compared to 11 ...

Infrequently omitting a sound from a repetitive sequence elicits the mismatch negativity (MMN) ERP response when the stimulus onset asynchrony (SOA) is less than 200 ms. We contrasted two alternative explanations of omission MMN. (1) Each sound starts a separate temporal integration process. Omissions violate the constancy of the temporal structure within ...

The mismatch negativity (MMN) is observed following rare or unique sensory events, and reflects pre-attentional sensory processing of unexpected stimuli. The MMN is altered in several mental illnesses, including post-traumatic stress disorder (PTSD), but did not yield consistent results. We measured MMN in 27 survivors of the Wenchuan earthquake, including ...

Mismatch negativity (MMN), observed in event-related potentials (ERPs), constitutes a measurable change in electrophysiological brain activity occurring after exposure to a novel stimulus. In humans, MMN is considered to be related to stimulus discrimination at the cortical level. ERP recording in dogs may present an opportunity to increase understanding ...

In an auditory four-alternative forced choice localization task, participants had to localize one of two simultaneously presented sounds while ignoring the location of the second sound. Negative priming--that is, slowed-down responses to a location that had to be ignored in the previous trial--was found only when the sound at the repeated location changed between prime and ...
