Fig. 4. MAO-B, but not MAO-A, is responsible for tonic GABA current in the striatum.

a Representative image of whole-cell patch-clamp of a neuron in the dorsal striatum. b Timeline of whole-cell patch-clamp. c Representative traces of tonic GABA recording (left) and sIPSC currents. d Quantification of tonic GABA currents (N = 5 mice for each group). Tonic GABA current is significantly reduced by MAO-B inhibition (KDS2010), but not by MAO-A inhibition (clorgiline). e Quantification of sIPSC amplitudes. f Quantification of sIPSC frequency. Data represent mean ± SEM. **P < 0.01; ns, non-significant by Kruskal-Wallis test with Dunn’s multiple comparison test (d, e) or Brown-Forsythe and Welch ANOVA test with Dunnett’s multiple comparison test (f).
