The hippocampus has no major direct projections to the brainstem, but connects with NTS-projecting regions of the mPFC, such as the infralimbic cortex49, suggesting that hippocampal actions on autonomic function may be routed through the mPFC. Hippocampal stimulation decreases glucocorticoid secretion in rats and humans45, 46, whereas hippocampal damage increases stress-induced and in some cases, basal glucocorticoid secretion3, 44. Notably, lesion effects are most pronounced during the recovery phase of stress-induced glucocorticoid secretion, implicating the hippocampus how does current affect biodiversity in rivers and streams in regulating the termination of stress-initiated HPA responses. The autonomic nervous system provides the most immediate response to stressor exposure via its sympathetic and parasympathetic arms that provoke rapid alterations in physiological states through neural innervation of end organs. For example, the sympatho-adrenomedullary arm can rapidly increase heart rate and blood pressure by excitation of the cardiovascular system1. Importantly, excitation of the ANS wanes quickly — due to reflex parasympathetic activation —, resulting in short-lived responses.

By contrast, in the intermediate lobe, there is no effect of GCs on POMC mRNA levels due to the very low expression of GR (Wang et al., 2015). Most bodily cells have cortisol receptors, it affects many different functions in the body. Cortisol can help control blood sugar levels, regulate metabolism, help reduce inflammation, and assist with memory formulation.
