Neuroanatomy Flashcards
what is one way to cheaply measure ACC activity
EEG or fMri
what is ERN
error related negativity
where does ERN come from
the ACC
when does ERN activity occur
when we make mistakes and are aware of it
what is SAT
speed accuracy trade off
what are two theories of error processing
conflict monitoring theory
action outcome evaluation/reinforcement learning theory
what is conflict monitoring theory
error as a special case of high conflict
what is reinforcement learning theory
errors and conflict are undesirable and reflect worse than expected outcomes
what is a strategy for overcoming conflict monitoring theory
addition of a single unit that measures the degree of onflict- connected via inhibitory links
what is an example of an inhibitory link
right hand active, left hand inactive
what is a measure of conflict
Hopfield energy in response system
energy of networks defined as sum of energy over all pairs of units
what increases conflict
absolute activation of competing representations
what are two potential implementations of performance monitoring in the brain
specialised system for error detection or one generic system for response competition monitoring
what is the conclusion of existence of brain systems for conflict
2 funcitonally and anatomically different systems
what are two brain regions for conflict montioring
ACC= error detection pre-SMA= conflict monitoring
