Karius Physio DSA Flashcards
which region of the brain has a lot of emotions going on with it?
-The limbic system
-means border
-
What does the limbic system control?
- emotional behavior
- motivational drives
what does the hypothalamus do?
- emotional experience
- links the physiological responses to the emotions*
Olfactory area
-linked with emotion and smell
Thalamus
- anterior nucleus part of papez circuit
- inputs and outputs… relaying things
Basal ganlia
- nucleus accumbens= plesure
- putamen= disgust
hippocampus
-memory
Amygdala
- fear and anger
- role in learning and memory
cingulate cortex
- many of these neurons show after-discharge!!!
- can’t let it go
what was that important thing she said about emotion?
-it appears that the neural circuits for recognizing emotion in others are also involved in producing that emotion in ourselves
what is the deal with mirror neurons?
-when someone smiles, we smile
What are the 2 kinds of fear?
- innate (unconditioned): requires no experience, olfactory clues (pee)
- learned (condition): we learned it from experience.. most common in humans, can be indirect… horror movie moneymaker
What does the amygdala do again?
-process and recongize the social cues related to fear
2 pathways for emotional conditioning in response to fear
- direct thalamo-amygdaloid (early response)
- indirect thalamo-cortical-amygdaloid (late response)
where do inputs come in from the amygdala
-thalamus and the cortex via the lateral nucleus of the amydala is what actually integrates things
What is the next step in the amygdala?
- the central nucleus
- then goes to the hypothalamus and it does things
Disgust
- insular corex/putamen
- processing and recognition of social cues related to disgust
- damage (including huntington’s disease) abolishes
Anger/rage
- amygdala
- requires dopaminergic input acting at D2 receptors*
Anger/rage
- amygdala
- requires dopaminergic input acting at D2 receptors*
what is required for the inhibition of anger/rage?
- neocortex
- vertomedial hypothalamic nuclei
- septal nuclei
step 1 of integrating the inputs?
- Anterior cingulate cortex
- regulation of affect (“controlling our emotions”)
- kind of figures out what is going on
Step 2
-pre frontal cortex
2 parts of the pre frontal cortex
- ventromedial PFC** know this one
- dorsolateral PFC
Probably roles for PFC
- reward processing
- integration of bodily signals
- top down regulation: delayed gratification
