N1575Y does not alter inactivation kinetics. (A) Representative current traces. The sodium currents were elicited by a 20-millisecond depolarization to 0 mV from the holding potential of −120 mV. (B) Voltage dependence of the sodium current decay. Time constant of sodium current decay was calculated by fitting the decaying part of current traces, elicited by a series of depolarizing voltages, with a single exponential function.
