[The specific features of the work of the visual mechanisms in the right and left hemispheres of the human brain].
Disturbances in the visual perception were analysed in groups of patients after commissurotomy, unilateral electroshock therapy, local brain lesions in the structure of the visual system. Three groups of symptoms were distinguished, i. e., deficit in attention switching, defects of image fragment recognition, and disturbances in assessment of special relations between the fragments and their groups. It was shown that these groups of symptoms were variously expressed in disorders of visual perception during pathologically autonomous activity of the left or right hemisphere. A model concept of hemispheric specificity in the visual perception is developed.
