Table 1Electrophysiological properties of MSNs and FSIs
Values are mean±S.E.M.Abbreviations: Rmp: resting membrane potential, Rin: input resistance, Ap: action potential, AHP: afterhyperpolarizing potential. The AP amplitude was measured with respect to firing threshold level. Ap repolarization time refers to the time window between the spike peak and the AHP minimum value.*p<0.05, **p<0.005; Mann–Whitney's U-test.
