[Sex differences in the interhemispheric asymmetry of the transcallosal responses of the visual area in the cat neocortex].

Interhemisphere of homo- and heterotopic transcallosal responses were studied in visual cortex of 12 male and 12 female immobilized cats. The right hemisphere dominated by the amplitude of homo- and heterotopic transcallosal responses in males, whereas in females an individual asymmetry of EPs was observed. The interhemisphere asymmetry was shown to be higher in males than in females. These findings are discussed in terms of sex differences of the morphological asymmetry of visual area and of the interhemisphere asymmetry of visual functions.
