There are sex differences in the activation of the hypothalamo-pituitary-adrenal axis in response to stress, but the source of these differences is unknown. The hypothalamo-pituitary-adrenal axis is regulated by corticotropin-releasing hormone and arginine-vasopressin neurones located in the paraventricular nucleus and these, in turn, are regulated by neural systems that include afferent noradrenergic and neuropeptide Y (NPY)-producing neural pathways. We tested the hypothesis that… CONTINUE READING
