title: [LAMINAR LOCATION OF NEURONS PROVIDING INTERHEMISPHERIC CONNECTIONS IN THE VISUAL CORTEX IN CATS WITH IMPAIRMENTS OF BINOCULAR VISION].
abstract: The distributio of cells in the visual cortical layers of intact cats (n=7) and cats with experimentally induced strabismus (n=10) and monocular deprivation (n=5) was studied after microiontophoretic injection of horseradish peroxidase into the ocular-dominance columns in areas 17, 18 and the transition zone 17/18. It was found that in cats with impaired binocular vision, the callosal cells were located deeper in layers of I/II, and higher - in layer IV, as compared to those in intact cats. Also in cats with impaired binocular vision, the proportion of callosal cells in layer IV was increased, while in layers II/III it was reduced as compared to intact cats. The most pronounced changes were noted in monocular deprived animals. These findings suggest an important role of sensory input in the formation of the callosal neurons layer distribution.
