[Sexual dimorphism of the transcallosal connections in the neocortex of the right cerebral hemisphere in cats].

Analysis of the amplitude-temporal characteristics and of topographic features of hetero- and homotopic EPs led from projection and associative cortex, was performed in 60 male and 60 female immobilized cats. Homotopic EPs had a greater amplitude and time parameters and were found in a larger area of the projection cortex in female cats as compared with the male ones. The positive component and time parameters of the homotopic EPs were greater in females' associative cortex, whereas the negative component as well as the recording area in the parietal cortex were greater in males. The brain of female cats seems to be organized more bilaterally as compared with the brain in males.
