11 Emotion Flashcards
Basal nucleus (B)
Nucleus of the amygdala that receives information from the lateral this and sends projections to the ventromedial prefrontal cortex and the central nucleus.
Lateral nucleus (LA)
Nucleus of the amygdala that receives sensory information from the neocortex, thalamus, and hippocampus and send projections to the basal, accessory basal, and central nucleus of the amygdala.
Central nucleus (CE)
Region of the amygdala that receives information from the basal, lateral, and accessory basal nuclei and sends projections to a wide variety of regions in the brain; involved in emotional responses.
Conditioned emotional response
Classically conditioned response that occurs when a neutral stimulus is followed by an aversive stimulus; usually includes autonomic, behavioral, and endocrine components such as changes in heart rate, freezing, secretion of stress-related hormones.
Ventromedial prefrontal cortex (vmPFC)
Region of the prefrontal cortex at the base of the anterior frontal lobes, adjacent to the midline.
Threat behavior
Stereotypical species-typical behavior that warns another animal that it may be attacked if it does not flee or show submissive behavior.
Defensive behavior
Species-typical behavior by which an animal defends itself against the threat of another animal.
Submissive behavior
Stereotyped behavior shown by an animal in response to threats behavior by another animal; serves to prevent an attack.
Predation
Attack of one animal directed at an individual of another species on which the attacking animal normally preys.
Affective blindsight
Ability of the person who cannot see objects in his or her blind field to accurately identify facial expressions of emotion while remaining unconscious of perceiving them; caused by damage to the visual cortex.
Volitional facial paresis
Difficulty in moving the facial muscles voluntarily; caused by damage to the face region of the primary motor cortex or it’s subcortical connections.
Emotional facial paresis
Lack of movement of facial muscles in response to emotions in people who have no difficulty moving these muscles of voluntarily; caused by damage to the insular prefrontal cortex, subcortical white matter of the frontal lobe, or parts of the thalamus.
James-Lange theory
Theory of emotion that suggests that behaviors and physiological responses are directly elicited by situations and that feelings of emotions are produced by feedback from these behaviors and responses.
