[Anatomo-physiological bases of residual vision following lesion to the primary visual area. Contribution to electrophysiological approach in monkeys].

This paper presents several studies aimed at determining which brain structures are responsible for residual vision observed after a lesion of the primary visual area. A description of this phenomenon in man and in monkeys is first provided. Recent results are then described that indicate that residual vision is mediated by the dorso-parietal pathway of visual information transfer. The ventro-inferotemporal pathway is inactivated by a block or a lesion of the primary visual cortex.
