Visual Cortical Unit Response Properties in Kittens given Brief Monocular Experience Following Dark Rearings.

Abstract

Single unit recordings were obtained from 300 cells in area 17 of 20 kittens. The subjects were reared in the dark from about 2 until 6 weeks of age. Immediately prior to recording, brief periods of visual experience were allowed with one eyelid closed. Kittens were tested after 0, 1, 2, or 7 days of monocular experience. Responses to light bars moving in each of 12 directions presented to each eye were analyzed to provide quantitative indices of ocular dominance, orientation selectivity, and reliability for each cell. The results suggest that visual experience following dark rearing leads to a rapid improvement in evoked responsiveness, reversing the degradative effects of the deprivation.
