Emotion (4) Flashcards
how are emotions produced according to the James-Lange theory
emotional experience is produced in response to physiological/somatic changes
how are emotions produced according to the Cannon-Bard theory
emotional experience/expression are parallel processes that have no causal relation
how does the somatic marker hypothesis combine both theories of emotion
this hypothesis says that signals arising from internal and external environment (emotional stimuli) act to guide behavior and decision making (unconscious process)
what is the limbic circuit and what brain regions are included in it
anatomical circuit of several interconnected brain structures involved in emotional connection and experience
hippocampus, amygdala, hypothalamus, thalamus
according to Papez, which brain region is responsible for emotional experience
cingulate cortex
according to Papez, which brain region is responsible for emotional expression
hypothalamus
what are the functional effects of rabies and lesions of the limbic system
rabies: hyperemotional responses
lesions: spontaneous laughing/crying
what is Kluver-Bucy syndrome and what are some symptoms
bilateral removal of the amygdala or anterior temporal lobe
symptoms: flat emotions, consumption increase/exploring things my mouth, increased/inappropriate sexual activity, lack of fear/reduced aggression
which part of the brain is affected in Kluver-Bucy syndrome
amygdaloid complex
which brain region is associated with emotional activation other than the hypothalamus
central nucleus of the amygdala; mostly associated with fear
what happens when there is damage to the amygdala
reduced fear reactions
what functions/emotions are associated with the amygdala
fear, aggression, reward behaviors
which part of the brain normally prevents aggression
diencephalon (forebrain) usually inhibits the hypothalamus which prevents aggression
what is the difference between affective and predatory aggression
affective: for show; activated in the dorsal longitudinal fasciculus/periaqueductal grey
predatory: attacks against different species for food; activated in the medial forebrain bundle/ventral tegmental area
