-decreased gray matter in frontal and temporal lobes, increased volume in corpus callosum. Psychopaths are wired differently. Largest cortex difference are clusters related to insula,
-decreased volume of amygdala and striatum
-reduced functional connectivity between amygdala and vmPFC, and hippocampus, amygdala, and OFC
-in psychopathic offenders,
widespread decreases in connectivity in almost every way
-decreased activity in cingulate, insula, amygdala, [tasks involving emotion, memorizing]
-increased activity in the frontal cortex [regions related to inhibition, processing info.]
decrease in emotional processing, increase in info processing
but this doesnt always happen [this is a specific study]
-Increased activity in amygdala, frontal/temporal/parietal/occipital cortices
-Decreased activity in cingulate,
temporal/occipital cortex
on some tasks, there are increases in emotion
Psychopaths show a deficit in startle with gory pics. There's a lot going on in these pics, a lot of processing to decide that this person is skiing down a mountain. So we manipulate how much processing is required in a pic: like familiarization, so you don't need to process as much. For novel pics, ppl saw the exact same deficit. Psyhcopaths don't show emotino-modulated startle,
no increased startle to unpleasant pics. But when they show familiar pics, the psychopaths process normally, further supporting idea of attention-based model. They have an attentional bias that preclude simultaneous processing of info .It's hard for them to sort multiple pieces of info. When they're focused on a goal, they don't focus on anything else. They show reduction in emotionality, but only situational. This contributes to their feelings of fearlessness, callousness, etc.
Feelings are
pretty much peripheral. Psychopaths are pretty adaptive. There's a side to psychopathy that's actually adaptive and helpful.
