Unitary responses to sound stimulation obtained from the cerebellar cortex were investigated in cats. Results obtained are as follows : 1) Under barbiturate anesthesia, 2 out of 75 units responded to the sound stimulation, while in curraized cats 23 out of 100 units responded. 2) Two types of response were recorded. One was a response to the onset of the stimulation, "on response", and the other was a response during the stimulation, "continuos response". 3) In some units which showed "continuos response", the number of spikes responding to tone bursts of constant intensity increased and decreased quency were made from the responses of 11 units. ency range and were at high intensity levels of characteristic frequencies with one exception. The exception showed relatively low thresholds and the threshold at its characteristic frequency, 9, 000c.p.s., was 20db S.P.L. 5) At some frequencies some units responded to strong stimulation and did not show any response to weaker stimulation, but still weaker stimulation caused responses again.
