↵† Action potential duration at half-maximal amplitude; * P ≤ 0.05; ‡ P ≤ 0.01 vs. E16; § P ≤ 0.05 vs. E18. ^a Input resistance was calculated from the voltage responses to injections of small hyperpolarizing current pulses (400 ms, 10–30 nA). ^b Mean rheobase was determined by dividing the threshold potential by input resistance. ^c Time constant was obtained by fitting the voltage transient induced by the injection of hyperpolarizing current to an exponential function.
