[Reciprocal influence of cortical zones in normal cats and after creation of an experimental pathologic process].

Acute experiments were conducted on non-anesthetized lystenon-restricted cats. The evoked potentials method was applied to the study of interaction of various cortical areas of one hemisphere and interhemispheric relations using stimuli of different modalities. It was shown that the action of somato-sensory areas on the visual cortex responses in the intact brain were mainly of a releasing character; these effects disappear in the formation of an experimental pathological focus. On the basis of the data obtained a conclusion was drawn on a possible participation of functional reorganization of the interhemispheric relations in the compensatory process mechanisms.
