Figure 3. The effects of NYT on the electrophysiological properties of MSNs in the NAc shell subregion. (A) The representative membrane potential recordings obtained by 200 pA current injection. The relationship of (B) firing frequency, (C) first spike latency and (D) interspike interval obtained by positive current injections (n = 11 from nine mice). (E) The representative membrane potential recordings obtained by negative current injections. (F) The I-V relationship obtained by negative current injections (n = 11 from nine mice). (G) The input resistance in -800 pA (left) and -200 pA (right) current injections (n = 11 from nine mice). (H) The resting membrane potential (n = 9 from six mice). (I) The representative current recordings obtained by voltage pulses. (J) The I-V relationship obtained by voltage pulses (n = 6 from four mice). Error bars are expressed as mean ± SEM. Statistical analyses were performed by one-way or two-way RM ANOVA followed by Dunnett’s multiple comparisons test, *p < 0.05, **p < 0.01, ***p < 0.001; Baseline vs. NYT, #p < 0.05, ##p < 0.01, ###p < 0.001; NYT vs. Washout. The arrows indicate the time points of analysis.
