[Reorganization of callosal interhemispheric connections in the adult cat: effects of monocular occlusion after chiasmotomy].
Two groups of adult cats were chiasmotomized and their cortical receptive fields (17-18 boundary) were compared after a postoperative period of ca 6 weeks. In one group, binocular vision was maintained during that period, in the other one, one eye was sutured at the time of the chiasmotomy, depriving one hemisphere from patterned vision through the direct pathway. In monocular chiasmotomized animals, the receptive fields to stimulation of the contralateral eye were significantly larger than in the binocular ones.
