Sex differences in activated corticotropin-releasing factor neurons within stress-related neurocircuitry and hypothalamic–pituitary–adrenocortical axis hormones following restraint in rats

Highlights ► Similar qualitative stress-induced neurocircuitry activation in male and female brain. ► Females have higher activation of PVN, BST, and MPOA after restraint stress. ► Females have higher stress-induced activation of CRF circuitry. ► Estradiol does not always augment stress-induced HPA...

Zusammenfassung:	Highlights ► Similar qualitative stress-induced neurocircuitry activation in male and female brain. ► Females have higher activation of PVN, BST, and MPOA after restraint stress. ► Females have higher stress-induced activation of CRF circuitry. ► Estradiol does not always augment stress-induced HPA axis activity.
