Antisocial bx + Frontal Lobe Flashcards
What happened to patients with antisocial pd?
Had 11% reduction in gray matter, where they had smaller prefrontal, which gave them less impulse control.
Also unsuccessful psychopaths had 22% reduction in prefrontal gray matter
Tell me about PSYCHOPATHY & PFC Thickness?
Lit report shows reduction in prefrontal gray matter volume, gray matter loss in the Right Superior Temporal Gyrus, amygdala, volume loss, decrease in porterior hippocampal vol, exaggerated structural hippocampal asymmetry, and increase in callosal white matter volume in psychopathic individuals.
What’s the connection between SEROTONIN and Prefrontal Lobes?
There is decreased activity of SEROTONIN neurons associated with increased risk taking and aggression (as said earlier)
also PFC is activated by large SEROTONIN pathways!
What is instrumental aggression?
aggression towards a goal
What is impulsive?
emotional flare up causing aggression
What happens to SEROTONIN during impulse?
Doesnt activate PFC in this case and it lowers 5-HT transporters.
