Weaker brain links found in psychopaths

Decreased communication between emotional and executive centers may contribute

Brain differences might help explain psychopaths’ cold, calculated and often antisocial behavior, and perhaps even point out better ways to treat or prevent the disorder, a study of Wisconsin prison inmates suggests.

Psychopaths have a weaker connection (green) between a part of the prefrontal cortex (red) and the amygdala (blue), a brain scanning study finds.
