Decision-Making Flashcards
(14 cards)
What brain region is associated with going against the framing effect and fear impulse?
Dorsomedial prefrontal cortex (DMPFC)
inhibits amygdala
what brain region is associated with being resistant to the framing effect?
seeking the best reward possible
Ventromedial prefrontal cortex (VMPFC)
what regions are associated with fear/loss aversion?
- amygdala - external threats
- anterior insula - internal state
what region is the reward system?
ventral striatum (nucleus accumbens)
What are the three projections of the reward center?
- medial frontopolar cortex
- medial orbitofrontal
- VMPFC
what region is associated with long-term goals?
frontopolar cortex
What are regions activated despite when reward was taken (delayed or not)?
visual cortex, premotor area
what regions are associated with impulse control?
- dorsolateral prefrontal cortex (DLPFC)
- lateral orbitofrontal cortex (LOFC)
delay discounting
what regions are associated with reward and impulse?
- posterior cingulate cortex
- MPFC (MOFC + VMPC)
- ventral striatum
what regions are associated with the endowment effect?
- insula - reluctant to sell something they owned
- MPFC - price increased for buying or selling; better deal
what happened when there was a lesion in the VMPFC?
gamble more, but still adjust size of bets with increasing risk
what happened when there was a lesion in the insula?
ignored degree of risk when deciding what to bet
what region is associated with external values?
DLPFC
what region determines subjective value?
orbitofrontal cortex
