Stress and anxiety/depression: poster should be one slide. Next friday!: amygdala can allow prediction of negative or positive event. Pairing of emotional response with external cue.

Theory that extreme stress can actually lead to overgeneralizations of fear- invoking stimuli. Possibly because of lots of stressful experiences with stressful stimuli, system involved with amygdala becomes hyperactive. Could be connected to generalized anxiety disorder: alterations in function of hippocampus and amygdala. Hpa response leads to release of cortisol from release of adrenal cortex (in abdomen. ) When move into more chronic stress- release of cortisol provides some feedback to brainstem saying that stress is still happening. That can affect the activity of the locus coeralleus which releases norepinephrine (adrenaline)
