Visual cortex damage in newborn kittens produces a 78% loss of retinal X-cells whereas damage in adult cats produces only a 22% loss. Retinal Y- and W-cells are unaffected. The present experiment showed that the critical period for the severe loss of retinal X-cells ends between birth and 2 weeks of age. These results have implications for understanding the neural mechanisms of recovery from early visual cortex damage.
