Scientists have found that psychopaths who murder and rape others have faulty connections between the part of the brain that deals with emotions and handles impulses and decision-making, Reuters reported.
The British scientists observed psychopaths who had committed murder, manslaughter, multiple rape, strangulation and false imprisonment, and found that roads linking the two crucial brain areas had "potholes," while those of non-psychopaths were in good shape.
Dr. Michael Craig of the Institute of Psychiatry at London’s King’s College Hospital said the study opens up the possibility of developing treatments for dangerous psychopaths in the future, and may have profound implications for doctors, researchers and the criminal justice system.
