Vehicle: Medium treatment; ChABC: ChABC treatment.
Cell number (n) for Vehicle and ChABC was 16, and 22, respectively. Cells from 5 rats.
Note that there were group differences in threshold, current required for evoked AP, latency for evoked AP, AHP amplitude, and S1S2 interval.
indicate p < 0.05, 0.01, respectively.
AP: Action potential; AP duration was measured at the width of 50% AP duration (APD50); AHP: Afterhyperpolarization; Input Res: Input resistance.
