[Interhemispheric transmission of visual information: behavioral and electrophysiologic aspects].

Efficiency of callosal and extracallosal channels of interhemispheric transfer of visual information was studied by behavioural and electrophysiological methods on cats with sections of classical and commissural pathways of the visual system. The results showed a high ability of the operated animals to form conditioned defensive reflex to visual stimuli. The primary complexes of evoked potentials to light flashes in the projection cortex of both hemispheres were also preserved. The data show the significant role of the callosal and extracallosal pathways of the transmission of visual information across the midline.
