Processing of vowels in supratemporal auditory cortex.
The auditory evoked neuromagnetic fields elicited by synthesized vowels of two different fundamental frequencies F0 were recorded in six subjects over the left and right temporal cortices using a 37-channel biomagnetometer. Single equivalent current dipole modeling of the fields elicited by all vowel types localized activity to a well-circumscribed area in supratemporal auditory cortex in both ...
متن کاملEncoding of Illusory Continuity in Primary Auditory Cortex
When interfering objects occlude a scene, the visual system restores the occluded information. Similarly, when a sound of interest (a "foreground" sound) is interrupted (occluded) by loud noise, the auditory system restores the occluded information. This process, called auditory induction, can be exploited to create a continuity illusion. When a segment of a foreground sound is deleted and loud...
متن کاملRepresentations of cat meows and human vowels in the primary auditory cortex of awake cats.
Previous investigation of neural responses to cat meows in the primary auditory cortex (A1) of the anesthetized cat revealed a preponderance of phasic responses aligned to stimulus onset, offset, or envelope peaks. Sustained responses during stationary components of the stimulus were rarely seen. This observation motivates further investigation into how stationary components of naturalistic aud...
متن کاملSpectral-ripple representation of steady-state vowels in primary auditory cortex.
Responses to various steady-state vowels were recorded in single units in the primary auditory cortex (AI) of the barbiturate-anaesthetized ferret. Six vowels were presented (/a/, /epsilon/, 2 different /i/'s, and 2 different /u/'s) in a natural voiced and a synthetic unvoiced mode. In addition, the responses to broadband stimuli with a sinusoidally shaped spectral envelope (called ripple stimu...
متن کاملCategorical perception of vowels
The present research aimed at investigating the difference in perception between normal, underspecified, and overarticulated, isolated vowels. Unexpectedly, we found observed discrimination to be worse than predicted by the labelling data. There was no difference in the degree of categorical perception between the two vowel conditions.
