title: Responses of fastigial single neural units to transfolial electrical stimulation of the cerebellar cortex in the cat.
abstract: In anesthetized cats, we recorded the responses of single neural units in the fastigial nucleus to electrical stimulation of the posterior vermal surface of the cerebellar cortex. Stimulus frequencies of 0.3 Hz, 10 Hz, and 200 Hz were used and the responses were similar at each frequency. Two principal responses were found: suppression-activation sequences and suppression followed by return to baseline. The former were found in the caudal portions of the nucleus and the latter along with the majority of nonresponsive units were found in the rostral portions. An area of overlap was found in the central portion of the nucleus.
