Cholinergic mechanisms in the reticular control of transmission in the cat lateral geniculate nucleus.


1. We examined the hypothesis that the ascending reticular arousal system influences thalamic transmission through a cholinergic mechanism. Extra- and intracellular recordings were obtained from neurons of the dorsal lateral geniculate nucleus (LGNd) and the perigeniculate nucleus (PGN) of cats anesthetized either with N2O and pentobarbital or with N2O and… (More)
