  • Values are means ± SD with the number of experiments in parentheses. Membrane potential, resting membrane potential; threshold, action potential amplitude, and action potential duration, as defined in Fig. 1; I Na max, maximum current;V 50, half-maximal current; s, slope factor. P values were obtained using 2-sided unpairedt-test.
