title: Reorganization of the uncrossed visual pathways as revealed by Fos-like immunoreactivity in rats with neonatal monocular enucleation.
abstract: To elucidate the neuronal characteristics of the functional expansion in the uncrossed visual pathways (UXVPs), resulting from early monocular enucleation in rats, the feasibility of stimulus-dependent induction of the immediate early gene c-fos was examined immunohistochemically. In the UXVPs of rats with monocular enucleation at birth, patterned visual stimuli induced Fos-like immunoreactive (FLI) neurons much more densely in wide areas of the superficial layer throughout the superior colliculus (SC), and in the striate and extrastriate areas of the visual cortex (VC). In the UXVPs of rats monocularly enucleated after maturity, however, only a few stimulus-dependent FLI neurons were scattered in the restricted portions of the SC and the VC.
