[The hemispheric functional specialization of visual perception].
In this review the modern concepts on psychophysical mechanisms of hemispheric functional specialization of human visual perception are considered. The problems are discussed on three basic historical aspects: interhemispheric relations in patients with localized cerebral lesions, interhemispheric differences in the "Bisected Brain", and the functional asymmetry in the intact brain. The neuropsychological data on recognition of geometric figures, faces and objects, and also electrophysiological results on the event-related brain potentials are deliberated. Special attention is given to the own data of authors dedicated to importance role of the right hemisphere in the brain interhemispheric functional asymmetry in control subjects and alcoholics. Several problems on learning and influence of emotions on visuospatial recognition are discussed. The dichotomous approach to brain functional asymmetry are not shared, the hypothesis on intersupplementary cooperation in hemispheric specialization and interaction of the brain hemispheres are supported.
