Abstract
Unilateral suppression of extraocular proprioceptive afferents, which run through the ophthalmic branch of the 5th nerve, disrupted binocular binocular integration in the primary visual cortex of normally reared kittens, when it was performed between 4 and 8 wk of postnatal age. After 1 mo. 1/2 the visual cortical cells were exclusively, activated through 1 eye. A similar disorganization of binocularity was observed in visually deprived kittens when a unilateral lesion was performed at 6 wk of age. Apparently, the loss of binocular integration is caused by non visual factors, probably related to asymmetry between proprioceptive informations from each eye.This publication has 3 references indexed in Scilit:
