  • All data are expressed as means ±s.d. with the sample size given in parentheses.

  • ↵* P < 0.05 compared with the value of the first response (Wilcoxon signed-rank test).

  • ↵a Amplitudes of after-depolarization were measured 50 ms after the stimulus artefacts.

  • ↵b Amplitudes of after-hyperpolarization were measured at the peak.

  • ↵c Durations of after-hyperpolarization were measured as the times between the data points crossing the half-maximum amplitudes.
