  • 摘要:Rabbit pups had one eye sutured closed before the time at which the eyes normally open. At 20-27 days of age, single-unit recordings were made both from the striate cortex contralateral to the sutured eye (deprived cortex) and from that contralateral to the eye which had opened normally (control cortex). The percentages of units encountered which fell into various receptive field categories differed on the two sides. The deprived cortices had a lower percentage of visually responsive cells, a higher percentage of indefinite cells, and totally lacked cells sensitive to orientation of a stimulus bar. In these respects they closely resembled previous observations on rabbit pups just before normal eye-opening. By contrast, the control cortices of the same animals were comparable to normally reared rabbits of the same age. We conclude, therefore, that developmental events which normally follow eye-opening can be affected in their time course by delaying eye-opening.
