Abstract

The distribution of callosal neurons in the cortical layers was studied in intact (n = 7) and experimental cats with strabismus (n = 10) or monocular deprivation (n = 5) after microiontophoretic administration of horseradish peroxidase into the eye dominance columns of fields 17 and 18 and the fields 17/18 transitional zone. Callosal neurons in cats with impairments to binocular vision were located more deeply in layers II/III and more shallowly in layer IV than in intact cats. In addition, the proportion of callosal neurons in layer IV increased and the proportion in layer II/III decreased in cats with impaired binocular vision, as compared with intact cats, and these changes were more marked in monocular deprivation. These data point to the important role of sensory information in the formation of the laminar distribution of callosal neurons.
