Summary of the postnatal ages of the animals used in electrophysiological recordings by group

	Male vehicle	Female vehicle	Male E2 treated	Female E2 treated
Average postnatal day	18.88	17.79	16.56	19.43
sem	0.93	0.74	0.58	0.48

E₂, Estradiol. Where there was a correlation between age and an electrophysiological measure, such as input capacitance, we compared the estimated marginal means after regression by Bonferroni tests to remove any bias that postnatal age might have on the raw means.
