In two animals, some of the recordings were obtained before the eyelids of the deprived eye were opened. Single neurons were recorded in the optic tract (OT), the lateral geniculate body (pars dorsalis, layer A and A.; LGN) and the OR by means of

Competitive Interactions in Postnatal Development of the Kitten’s Visual Systemations a secondary consequence of cortical changes. By rearing kittens with one eye viewing normally, while the other eye views through a cylindrical lens, we have been able to make binocular competition effects depend on the orientation preferences of cortical cells. Since orientation selectivity f

Evidence for a Central Control of Developmental Plasticity in the Striate Cortex of Kittens). These changes in neuronal circuitry are commonly attributed to competitive interactions between the afferents from the two eyes at their common cortical target cells (Wiesel and Hubel, 1965; Guillery, 1972; Cynader et al., 1977). Asymmetries in the activity of converging pathways are thought to l
