Less switching between large-scale brain networks among people with psychopathy
Psychopathic people are callous and deceitful, and they often break laws. Our new paper shows that psychopathic people’s brain networks interact differently than non-psychopathic people’s, adding to growing evidence. Read more

Or, more scientifically, what are the neural correlates of psychopathy?… Read more
