PMA enhances the rate of mEPSCs evoked by hypertonic sucrose solution. A, The mEPSCs evoked by a puff application of hypertonic sucrose solution (2 m) for 300 msec in the control (top), in the presence of 100 nm PMA (middle), and in the presence of 10 μm CNQX (bottom). B, The mEPSC evoked by a puff application of hypertonic sucrose solution (2m) for 3 sec in the control (top), in the presence of 100 nm PMA (middle), and in the presence of 10 μm CNQX (bottom). The initial rise of the current is an artifact of the puff application because it was not blocked by CNQX (bottom trace). All data in this figure were obtained from the same synapse.
