Striate cortex lesions and visual acuity of the rhesus monkey.

Abstract

Visual acuity was measured pre- and postoperatively in monkeys given resections of striate or inferotemporal cortex. Striate Ss showed decreases in acuity, the severity of which corresponded reasonably well with the completeness and location of the lesions. Temporal Ss showed no decrease. The drop in acuity shown by the striate Ss was less than would be predicted if the lesion produced an absolute scotoma and if the relation between foveal and parafoveal acuity is the same in monkey as in man.
