Visual form discrimination after removal of the visual cortex in cats.
Adult cats were trained to discriminate between erect and inverted triangles after simultaneous ablation of cortical areas 17, 18, and most of 19 of both hemispheres. Postoperative training proceeded through a graded series of similar triangle pairs in which the members of each pair were equated for luminous flux.
