Inhibitory effect of μ-opioid receptor activation on GABAergic mIPSCs in normal rats. (A) Representative recording trace of mIPSCs before and during the application of DAMGO (1 μM). (B) Histograms showing cumulative frequency (a) and amplitude distribution (b) of mIPSCs inhibited by DAMGO. (C) Each column is the mean of 49 neurons. All frequencies (a) and amplitudes (b) are normalized to those of control mIPSCs.
