-
Values given represent mean ± SD. AHP, after hyperpolarization.
-
↵F1-a Significant difference with p< 0.05.
-
↵F1-b Significant difference with p< 0.01.
-
↵F1-c AHP amplitude was measured from the spike take-off point to the peak of the AHP.
-
F1-d Time to peak of the fast AHP was measured from the time when, during the falling phase of the action potential, the membrane potential crossed the spike take-off point.
