Facial stimulation (1 Hz) induces long-term depression (LTD) of GABAergic transmission at PCs in mouse cerebellar cortex. (A) Upper, representative cell-attached recording traces showing air-puff stimulation (10 ms, 60 psi)-evoked responses in a cerebellar PC before (pre) and after (post) delivering 1 Hz (240 pulses) stimulation. Note that both amplitude of the positive component (P1) and the pause of SS firing are significantly decreased after 1 Hz stimulation. The lower panel shows the time course of normalized amplitude of P1 (shown in upper) before and after delivery of 1 Hz facial stimulation (arrow head). (B) Summary of normalized P1 amplitude under control conditions (squares; n = 7) and delivery of 1 Hz facial stimulation (arrow head; circles; n = 8). Note that air-puff stimulation at 1 Hz induced LTD of P1 in cerebellar PCs. Data points are mean ± SEM.
