Kinetics of the development of orientation tuning are inferred from quantitative analysis of extracellular recordings in the primary visual cortex of normally and dark reared kittens. 712 visual cells were classified in three functional groups: a) non-specific cells, and b) immature cells which are

The development of orientation selectivity in the primary visual cortex is described by first-order kinetics between three functional compartments chained in a catenary mode. A first model is presented, in which two unidirectional kinetics with constant exchange coefficients, symmetrical in their ef
The period of susceptibility of the visual cortex of kittens to the effect of squint is limited to the first three postnatal months. The reduction of binocularity found in these kittens as reflected by the distribution of neurons according to their ocular dominance is especially emphasized in animal
The functional organization of visual cortical cells was studied in two groups of five week old kittens: one group normally reared, the other reared in total darkness from the third day after birth. The following results were obtained: 1. The cells of the normally reared kittens were similar to adul
Visual callosal transfer during development was studied in order to reveal plasticity-related compensation for the absence of direct contralateral inputs. The optic chiasm was midsagittally sectioned in 6-8 weeks old kittens (OCK) and for comparison, in adult cats (OCA). Unit recording was made duri
