[Comparative characteristics of the topography of functional interhemispheric asymmetry in the visual cortex following exposure to stimuli of different strength].
It has been shown that most animals exhibit functional interhemispheric asymmetry in the visual cortex, which increases with a rise in the intensity of photic stimulation. Interhemispheric asymmetry is characterized by its bilateral origin and mozaic localization. In the intact brain the transcallosal mechanisms provide for weakening a weak asymmetry and intensifying a strong one. This is due to different lateralization of the excitation focus which possesses dominant properties. A conclusion has been drawn that one of the functions of the callosal body consists in modulating the functional interhemispheric asymmetry.
