โœฆ Synopsis

In cats under nembutal or chloralose anesthesia, unilateral temporary cryogenic blockades of the primary visual cortex were performed and their influence on unitary responses to restricted light spots was tested in the ipsilateral geniculate nucleus. No significant effect could thus be observed, at variance with previous positive results obtained by our group in structures like superior colliculus and pulvinar complex using the same experimental procedure.

The spontaneous firing of single units in the cat's visual cortex, and their responses to repeated presentations of a constant visual stimulus, have been analysed quantitatively. Although the responses of most cells showed some habituation to the stimulus, this was less extensive than the fluctuatio

## Abstract The functions of the visual cortex (VC) were interrupted in anesthetized and paralyzed hooded rats with KCl (3M Baker) applied topically and single unit recordings were performed on lateral geniculate cells. Responses of geniculate cells to diffuse 1 second flashes were tested prior to
