[Features of the afferent control of spike activity of neurons of the interstitial nucleus of the cerebellum in the awake cat].

Characteristics of neuronal responses of the cerebellar nucleus interpositus to electrical stimulation of limbs were studied in alert cats. Somatosensory inputs to neurons of the nucleus are transmitted, mainly, via short--latency afferents without involving the cerebellar cortex. Nembutal anesthesia sharply reduced the number of early excitatory reactions and increased the number of inhibitory responses. The latters with latency up to 30 ms disappear after subcortical transection of the intermedial zone of the cerebellar cortex.
