ELECTRN 8 Lecture Notes - Lecture 4: Somatic Marker Hypothesis, Frontotemporal Dementia, Reduced Properties
Document Summary
Neurobiology in neuropsychology & law: complete summary of relevant region. Function = involved in social, moral, emotional and cognitive processes; executive functions. Psychopathic adults = reduced volume and thickness, white matter reductions, reduced integrity of uncinated fasciculus , reduced connectivity between amygdala and vmpfc, reduced pfc activation during fear conditioning. Function = self-regulatory processes (e. g. attention + cognitive. Exibility: damage = impulsivity, poor behavioural control, impaired problem solving, environmentally bound behaviour. Reduced activity during moral decision-making task in psychopaths: decreased activity in individuals with high psychopathy during go-no- go inhibition task. Reduced activity during moral decision-making task in psychopaths: decreased activity in individuals with high psychopathy during go-no- go inhibition task vmpfc. Function = linking potential decision outcomes to an associated emotion/somatic state based on previous experiences of reward/punishment which effectively marks the outcome as something to pursue or avoid (somatic marker hypothesis); representing the value of goal-directed outcomes and options.
