Unitary responses to tone stimuli obtained from the cerebellar cortex were investigated in cat. Inhibition or phenomena similar to inhibitions among the responses were discussed as followed:1) Eighty-two out of 160 units showed some reactions to tone stimuli. While in 7 out of 160 units activities were suppressed by tone.2) In 4 out of the 7 units suppression occurred with a latency of 10 to 15 msec and lasted during the tone burst. One of the 4 units showed an "on-response" to a tone burst of high intensity before the activity was suppressed. With low intensity tone the activity of unit was suppressed without excitation.3) In the other 3 out of the 7 units suppression occurred with a latency of several msec and terminated with a duration of 10 to 20msec and was followed by an indistinct response of continuous type.4) In a unit which showed an"on-response"a short silent period followed the response at all but two frequencies tested. At those two exceptional frequencies this silent period was not seen.
