摘要：Experimental data was obtained from a dichotic listening test by patients with unilateralbrain lesions and corpus callosum pathology (agenesis, cysts, degenerative changes, etc).Efficiency index analysis shows that interhemispheric interaction in the audioverbal spheredepends to a greater extent on the right hemisphere state. The dichotic listening techniqueis not an informative means of studying hemispheric interaction, since it does not allow aclear distinction between hemispheric symptoms and symptoms of pathology of the corpuscallosum. Thus, violations of hemispheric relations caused by disorders of the corpus callosumand cerebral hemispheres change worth more right hemisphere activity.
