[The dynamics of interhemispheric asymmetry during the processing of a transcallosal signal].

Multiple homotopic transcallosal responses were led from the visual, temporal, auditory and motor cortical areas in Wistar rats. Temporal parameters of positive as well as negative components of the responses revealed alteration of the interhemispheric asymmetry by the rule of right-left-right shifting. By the amplitude parameters of negative components the asymmetry was right-left-right whereas by the positive oscillations amplitude it was left-right-left. The data obtained suggest a right-left-right pattern of domineering of the hemisphere cortex in processing of transcallosal signal.
