Mode of activation of thalamic neurons by stimulation of the cerebellar fastigial nuclei in the cat.
In thalamic neurons of Nembutal-anesthetized cats, stimulation of the fastigial nucleus facilitated the antidromic invasion of cortically-evoked spikes over a considerable period and induced a spike train with a wide variability of latencies. Intracellular recordings suggested that excitatory inputs through polysynaptic routes should underlie these effects of fastigial stimulation on thalamic neurons.
