MSN action potential properties. A, Voltage response of a male (left) and a female (right) MSN to a series of depolarizing current injections. B–G, The following action potential properties did not differ by sex: action potential threshold (B); afterhyperpolarization peak (C); delay to first action potential (D); action potential width (E); action potential amplitude (F); and action potential afterhyperpolarization time to peak (G). The horizontal line in B through G indicates the mean. The p value within each subpanel indicates statistical significance; complete statistical information is in Table 1.
