FIG. 2.
Estradiol alters inactivation of IA. All data are means ± SEM. A) IA inactivation (as normalized current) is shown as a function of command potential. B) Summary bar graphs show the effects of estradiol and time of day on subtracted IA current density following −100 mV prepulse (left) and IK current density following −40 mV prepulse (right) in GnRH neurons from OVX mice (morning, n = 11; evening, n = 11) and OVX+E mice (morning, n = 13; evening, n = 8) during morning hours (white bars) and evening hours (black bars). **P < 0.005; *P < 0.05. The test pulse was set at −10 mV. Significant differences in inactivation at −40 mV are observed between OVX evening and OVX+E evening and between OVX+E morning and OVX+E evening; these are not indicated in A for clarity (both, P < 0.05).
