The development of stereoscopic mechanisms in the visual cortex of the cat.

It is argued that those neural systems (such as that responsible for stereoscopic vision) that have the greatest precision of operation are the most likely, during their developmental construction, to take advantage of infromation supplied by their own input. There is evidence that binocularly driven neurons in the kittens's visual cortex do indeed become modified in their synaptic organization during early visual experience in a manner that enhances the specificity of binocular interaction and ensures that the ranges of positional and orientational disparities of the receptive fields, within limits, become matched to the nature of the actual stimulation encountered by the animal.
