BioCog 8B emotion Flashcards
six basic emotions
- anger
- disgust
- fear
- happiness
- sadness
- surprise
non-basic emotions
- mixes of one or more basic emotion
bodily reaction to anxiety
- sweat
- stress hormones
- faster breathing
- increased blood flow
- muscles tensening
- pain surpression
amygdala
- most important for emotion
potentiated startle
- rats fearful reaction to the conditioned stimulus
input for amygdala
- lateral nucleus (direct)
- basal nucleus (indirect)
informatioin processing for amygdala
- central nucleus
output from amygdala
- nucleus reticularis
nervus vagus
- inhibits PNS
paraventricular nucleus
- controls HPA-axis
paraticular hypothalamic nucleus
- from amygdala
- to hypothalamus
hypothalamus (in stress)
produces CRF
CRF
- stimulates pituitary
pituitary
- from CRF
- produces ACTH
ACTH
- from pituitary
- stimulates adrenal gland
cortisol
- stress hormone
- breaks up protein, releases glucose
- too much over long can damage hippocampus
- surpresses immune system
GABAergic neurons
- inhibit amygdala
serotonine
- excite GABAergic neurons
treatment for anxiety
- either benzos or SSRIs
vmPFC
- counterpart of amygdala
- rational decisions
- weighs rational gain against the emotional consequences
- social and moral decisions
hippocampus in stress
- retrieves memories
- so we fear a snake before we actually encounter one
chronic stress
= depressivity
- overactivation of HPA-axis
- too much cortisol
- eventually hippocampus damage
cytokines
- used for communication between lymphocites
- interfered by cortisol
lymphocites
- for immune responses
James-Lange theory
- emotions are merely result of bodily reactions
voluntary expressions
- no eye muscles
- left motor cortex
voluntary paresis
- right motor cortex damage
spaneous expressions
= automatic
- eye muscles
- both hemispheres
- subcortical regions
emotional paresis
- no spontaneous expressions
- left white matter damage
feedback loop face - feeling
- we make a happy face and become happy
- explains why we like to make other people laugh
