Inhibitory effect of μ-opioid receptor activation on GABAergic mIPSCs in neuropathic rats. (A) Representative recording trace of mIPSCs before and during the application of DAMGO (1 μM). (B) Histograms showing the cumulative frequency (a) and amplitude distribution (b) of mIPSC inhibited by DAMGO. (C) Each column is the mean of 35 neurons. All frequencies (a) and amplitudes (b) were normalized to those of control mIPSCs.
