  • 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.
