PSYC23H3 Lecture Notes - Lecture 4: Classical Conditioning, Cortisol
Document Summary
How body make decisions under this complex conditions. Mild hunger a little bit long study hours might be condusive. Early mechanisms of learning biology figure out best stragtegy of survival. Neutral stimulus and food (desire) easy to understand every time hear ns bell then expect food. Amygdala calcified no have amygdala urbach wiethe disease. Instinctual fear not enough exposure consciously afraid. No amygdala no fearful response that directs that behavior. And starts sending signals designed to deal with threat. Learn these chemicals that being release in level of these axes. Immediate effects of having hpa system activated once you detect threat. Glucocorticoids gcs cortisol in animals inject then avoidance behavior. Cortisol acting on dopa receptor that is going to produce fearful learning or avoidance behavior. Hpa axis remove adrenals where cortisols is secreted no more cortisols. Stress influence avoidance behavior chronic stress and triggers social aversion specific with how this works.
