Document Summary

Emotion: parts of emotional experience, detect emotional item e. g. moving object, initial emotional response, prepare to respond e. g. sweating, higher hr, muscle tension, analyze situation, increase/decrease response e. g. figure out object. What is emotion: emotion: behaviour of 3 components, subjective thought/experience, accompanying patterns neural activity, physical arousal, observable behavioural expression (e. g. facial expression) Emotion physiology: neural response = series of networks. Each network has neural structures work together = emotional response. Initial response: within 150 ms of detecting threat. Sensory cortices signal amygdala : notice stimuli. Amygdala feeds back, sensory cortices more attentive. Areas influence e/o: amygdala: nuclei group in medial portion of temporal lobe in each hemisphere brain. Sensory input from cortex (200 ms after stimulus) Emotional response produced by other brain structures, amygdala projects. Amygdala feedbacks to sensory areas, more attentive to stimuli: autonomic response: Parasympathetic ns: conserve energy, calms down: movement: Threatening emotional stimuli trigger movement-planning areas, spinal cord.
