[Vestibular reactions of neurons of the cerebellar nucleus dentatus and nucleus interpositus in cats]

Abstract

The response of interpositus and dentate neurons to the sinusoidal tilts in the frontal plane were studied in thalamic cats. In interpositus nucleus 65% neurons responded to the tilts. Their responses were not uniform: some neurons showed an increased activity during the contralateral tilt, others--during ipsilateral tilt, and some neurons--during tilts in both directions. Dentate neurons did not respond to tilts. The peculiarities of vestibular responses of neurons in different cerebellar nuclei are discussed.
