Abstract

The study investigated directional differences in interhemispheric transmission time using the VEPs method. Specificially we were interested in whether there exists an asymmetry in the transmission of information to and from the hemisphere specialized in its processing. Two typeof stimuli, specific for the left and right hemisphere, were presented in the left and right visual fields. The latency differences betweenvisual evoked potential components registered in the hemispheres ipsilateral and contralateral to the stimulated hemifield were compared. Interhemispheric transmission time was shorter when the information wastransferred from the hemisphere non-specialized for its processing tothe specialized one than in the opposite direction. The results suggest the existence of a physiological mechanism that ensures fast transmission of information to that hemisphere which is more efficient in its processing.
