when activated, the amygdala helps initiate the body’s stress response (including the secretion of glucocorticoids). The PFC works to end this stress response by calming down the amygdala. Elevated glucocorticoid levels impair PFC function; the PFC isn’t as good at calming the amygdala, resulting in the person secreting ever higher levels of glucocorticoids, which then impair…A vicious cycle.[36]
