[Postsynaptic potentials of the motor neuron of the facial nerve nucleus evoked by stimulation of the cerebellar nuclei].

Synaptic processes induced in the facial motoneurons by stimulation of the red nucleus and the cerebellar interpositus and dentate nuclei were studied in anesthetized and immobilized cats. The stimulation of the red nucleus evoked monosynaptic EPSPs in the motoneurons whereas oligo--and polysynaptic EPSPs were recorded in response to the stimulation of the interpositus and dentate nuclei. Based on the experiments with the lesion of the red nucleus, a conclusion was drawn about its participation in the mechanisms and pathways of the cerebellar influence on the facial motoneurons.
