PSYC 3 Lecture Notes - Lecture 28: Locus Coeruleus, Anterior Pituitary, Basal Forebrain
Document Summary
Makes delivery of blood to muscles efficient. Involved in release of acth from anterior pituitary. Increases energy availability (also, insulin secretion is suppressed) Stress induces ne release in the brain. Exposure to a stressor increases in ne. Via pathway from the central nucleus of the amygdala to the locus coeruleus. Amygdala is the threat detector that then runs or starts the stress response. Know the negative feedback in diagram on this slide. Glucocorticoids affect metabolic pathways to ensure that adequate energy is available. Increase appetite for food after stressful event. Increase food and seeking behaviors increased oxygen intake. Decreased blood flow to areas not necessary for movement. Pain perception (releasing opiates so you don"t have to deal with pain at this. Enhancement of memory (short term) and sensory function. Works with catecholamines to form memories of potentially dangerous time) situations. Really good at making a memory about the stressful situation, what youre not.
