Non-significant virgin and postpartum IHC mean density and one-way ANOVA results for each region or subregion tested.

Notes: The sample numbers listed above were the final sample numbers used for data analysis. A complete list of original sample numbers for each brain region can be found in the Methods section. Missing or torn sections led to some regions having fewer samples than others. # indicates that data failed the assumption of equal variance, and a Kruskal-Wallis ANOVA on Ranks was performed. The p-value for those regions are derived from the Kruskal-Wallis ANOVA on Ranks, while the mean ± SEM were taken from the results of the one-way ANOVA. Abbreviations: rLSD = rostral dorsal LS; rLSV = rostral ventral LS; mLSV = medial ventral LS; cLSV = caudal ventral LS; mPVN = medial PVN; lPVN = lateral PVN; cPVN = caudal PVN; CeA = central amygdala; PAG = periaqueductal gray; lPAG = lateral periaqueductal gray.
