The hypothalamic-pituitary-adrenal (HPA) axis and its response to stress stimuli: the signalling events (green, solid lines) in the HPA axis in response to stress stimuli and how glucocorticoids (GCs) produced by the adrenal gland can have a negative feedback role in maintaining GC levels in the blood. The negative feedback in the hypothalamus and pituitary (red, dotted lines) are both mostly regulated by glucocorticoid receptors (GRs), and dysfunctional negative feedback system is often seen associated with chronic exposure to stress stimuli
