Document Summary
A behaviour with the following 3 components: A) a subjective thought and/or experience with. B) accompanying patterns of neural activity and physical arousal and. C) an observable behavioural expression (i. e. an emotional facial expression or changes in muscle tension) Initial response: the amygdala fires when we perceive stimuli that is emotionally arousing. When the amygdala receives input about a stimulus that might be emotionally meaningful or threatening, it stimulates activity in sensory areas so that they fire more than they would for a non-emotional stimulus. 1) sympathetic nervous system (recruits energy to prepare you for a response. Nervous system (preserves energy and calms you down) Movement: threatening emotional stimuli triggers planning movements. Emotional regulation: frontal lobes receive info directly from the amygdala. They have access to highly detailed info about a stimulus/situation. They analyze the situation and agree that an emotional response is necessary, then generates behaviour that is appropriate. I. e. you should continue to run from that spider.
