[Responses of efferent neurons of the parietal association cortex to stimulation of cerebellar nuclei].

Neuronal organization of the cerebello-cortical loop passing through the associative parietal region of the cat cerebral cortex was studied with the microelectrode recording technique. Specific characteristics of the cerebellar signals to various types of neurons of the parietal cortex projecting to the pontine nuclei proper, the red nucleus and sensomotor cortex, were revealed by responses of the cortical neurons to stimulation of the cerebellar nuclei. The neurons of parietal cortex were shown to respond most readily to stimulation of the nucleus dentatus (62.3%), nucleus interpositus (54.6%), and nucleus fastigii (20.6%).
