title: [Characteristics of the transcallosal potentials in the parietal cortex of the cat].
abstract: Comparative study of the transcallosal EPs in the cat parietal and sensomotor cortical areas revealed that the parietal EPs were less stable and more uniform than the sensomotor ones. Distribution of the EPs over the sensomotor cortex's surface is more regular as compared with the parietal area. Focus of the transcallosal EPs maximal activity coincided usually with the parietal point symmetrical to stimulation. An individual form of functional interhemisphere asymmetry was revealed for the parietal cortical potentials. An inversion of positive-negative transcallosal EPs was shown to exist in the parietal area's IV layer. The data obtained seem to corroborate the opinion of different functional purposes of the areas under study which can be revealed by the interhemisphere interaction between these areas as well.
