title: [Comparative study of somatic and visual projections on the cerebral cortex of the normal adult rat, the rat enucleated at birth, and the young rat].
abstract: A comparative study of somatic and visual projections on the cerebral cortex of the adult of the normal rat or of the rat enucleated at birth, and of the young rat. This study was first designed to examine the developmental features of somate, sensory and visual projections to the rat cerebral cortex, together with their alteration as a consequence of early sensory deafferentation. We were led to a reevaluation of these projectins in the normal adult rat. This study specifically shows that topical projections exist, for both the somatic and the visual system. However, projections that are highly convergent in nature are present over most of the superolateral aspect of the cerebral cortex and we were unable to demonstrate any simple change resulting from early visual deafferentation.
