[Cerebellar control of the activity of caudate nucleus neurons].
Responses of the caudate nucleus neurons to stimulation of the cerebellar nuclei were studied in acute experiments on cats. 53% out of 267 neurons of the caudate nucleus responded to the cerebellar stimulation mostly with excitation. 83% of the cerebelloresponsive neurons reacted to the dentate nucleus stimulation, 63%--to the stimulation of the nucleus interpositus and 53%--to the fastigial nucleus stimulation. A high degree of convergence of the cerebellar influences onto the single neurons, was found. Antidromic stimulation of the caudate nucleus neurons revealed the effect of the cerebellar signals on the efferent neurons and interneurons of the caudate nucleus.
