Hemispheric asymmetries of visual and auditory information processing

The lateralization of visual and auditory functions, interhemispheric interactions and their relationship to speech dominance were studied. Spectral analysis of visual and auditory evoked potentials (EPs) recorded from left and right speech dominant subjects was employed. The results suggested a complementary processing of the temporal and spatial properties of the afferent information in the speech dominant and non-dominant hemispheres, respectively.
