Brain injury AO3 strengths
A
- Diaz was interested in the insanity plea. Plea relates to brain structure an function issues, including brain injury. He confirms common areas of damage are frontal, temporal and brain stem. Studies with frontal lobe damage relate to ASPD and criminal behavior.
- Blumer et al looked at case studies and found ASPD can rise after frontal lobe injury. Damage tends to be to orbitofrontal cortex and damage leads to lack of inhibition, outbursts when area previously responsible for decision making.
- Raine found murders pleading NGRI had low PFC and corpus callosum activity
