RMP, Resting membrane potential; AP, action potential; AHP, afterhyperpolarization. All values are mean ± SEM. All values are measured at the current step above threshold.
↵a Current injection is the amplitude of the injected current evoking action potential firing.
↵b AHP amplitude is measured from threshold to maximal afterhyperpolarization.
