[Characteristics of the stability of functional interhemispheric asymmetry in the cat visual cortex]

A study of EP topography in the cat visual cortex has shown that initial functional interhemispheric asymmetry may be reduced and replaced by symmetry through long and frequent binocular stimulation. Section of the callosal body produced an inversion of one hemisphere dominance. In the callosotomized animals binocular stimulation enhanced the asymmetry. It is more stable in the cat visual cortex than in rats.
