PSYC 211 Chapter Notes - Chapter 11: Facial Nerve, Antiandrogen, Mirror Neuron
Document Summary
Emotions as response patterns: behavioral: muscular movements appropriate to situation that elicits them. Autonomic: facilitate behaviors, provides quick mobilization of energy for vigorous movement. Fear: integration of components of fear controlled by amygdala. Single neurons in various nuclei of amygdala become active when emotionally relevant stimuli are presented. Located in temporal lobes, has several groups of nuclei w/ different inputs/outputs and functions. Medial nucleus: several subnuclei, get sensory input, take to medial basal forebrain and hypothalamus. Single most important part of brain for expression of emotional responses provoked by aversive stimuli neural activity and fos production increase. If damaged, many emotional behaviors and physio responses are reduced/extinguished. May be responsible for harmful effects of long-term stress. Conditioned emotional response: produced by neutral stimulus paired with emotion-producing stimulus specific and non-specific response. Physical changes responsible for classical conditioning happens in lateral nucleus of amygdala. In humans, amygdala related to fear, emotional responses, association with memory.
