Psychopaths have brain structure abnormality

Scientists have long searched for a biological basis for psychopathy, a behavioral disorder attributed to chronic immorality. While previous studies have found no clear evidence, Professor Declan Murphy of the Institute of Psychiatry at King's College London believes he has found an area of the brain that is decidedly different in a psychopath as compared to a normal person.

It is unsurprising that much of the research to date has focused on the amygdala (the part of the brain involved with emotions and aggression) and the orbitofrontal cortex (which deals in decision making). However, an unstudied area is the uncinate fasciculus (UF), a white matter region that connects the amygdala and the orbitofrontal cortex. While the UF may not have a direct behavioral role, its dysfunction may lead to abnormalities in the areas which it connects.
