Deficits in Binocular Depth Perception in Cats After Alternating Monocular Deprivation

Compared to normal cats these specially reared animals suffer deficits in binocular depth perception while retaining normal activity in the two eyes. Evidently, binocular cells play a crucial role in stereopsis.
