| Popis: | The recovery of orientation selectivity in the primary visual cortex has been studied in 6-week-old dark-reared (DR) kittens after visual exposure of various durations following bilateral section of either the ophthalmic (V1) or the maxillary (V2) branches of the Vth nerve. After 6 h of vision, visual cortical neurones become orientation selective in V2-operated kittens as well as in intact animals, while they remain non-specific in V1-operated kittens. However, in this latter case, if the duration of visual exposure is extended to 4 weeks, a slow and incomplete recovery of orientation selectivity takes place. |
