Language processing in the occipital cortex of congenitally blind adults.
Humans are thought to have evolved brain regions in the left frontal and temporal cortex that are uniquely capable of language processing. However, congenitally blind individuals also activate the visual cortex in some verbal tasks. We provide evidence that this visual cortex activity in fact reflects language processing. We find that in congenitally blind individuals, the left visual cortex be...
متن کاملAuditory-tactile speech perception in congenitally blind and sighted adults.
The present study investigated whether manual tactile information from a speaker's face modulates the intelligibility of speech when audio-tactile perception is compared with audio-only perception. Since more elaborated auditory and tactile skills have been reported in the blind, two groups of congenitally blind and sighted adults were compared. Participants performed a forced-choice syllable d...
متن کامل"Visual" Cortex of Congenitally Blind Adults Responds to Syntactic Movement.
UNLABELLED Human cortex is comprised of specialized networks that support functions, such as visual motion perception and language processing. How do genes and experience contribute to this specialization? Studies of plasticity offer unique insights into this question. In congenitally blind individuals, "visual" cortex responds to auditory and tactile stimuli. Remarkably, recent evidence sugges...
متن کاملVestibulo-ocular reflexes of adventitiously and congenitally blind adults.
The vestibulo-ocular reflex (VOR) was measured in congenitally blind, adventitiously blind, and normally sighted adults to determine how it was affected by loss of vision. VOR gain and phase were measured in subjects rotated sinusoidally in total darkness, while concentrating on an imaginary earth-fixed target. Gain was lower in adventitiously blind subjects than in sighted subjects. The gain r...
متن کاملCorrelates of contrastive focus in congenitally blind adults and sighted adults
PURPOSE The role of vision in speech representation was investigated in congenitally blind speakers and sighted speakers by studying the correlates of contrastive focus, a prosodic condition in which phonemic contrasts are enhanced. It has been reported that the lips (visible articulators) are less involved in implementing the rounding feature for blind speakers. If the weight of visible gestur...
