| Researchers have found evidence of brain abnormalities in psychopaths convicted of violent offences, including murder, rape and grievous bodily harm.
The British study, carried out by London's King's College, used magnetic resonance imaging (MRI) scans to measure the volume of grey matter in violent men's brains.
Psychopaths were found to have structural differences in parts of the brain responsible for understanding emotions compared with other violent offenders and non-offenders. Advertisement: Story continues below
The study, published online this week in the Archives of General Psychiatry, scanned the brains of 66 men, including 17 psychopaths with antisocial personality disorder (ASPD).
Twenty-seven men who were not psychopaths but had ASPD and 22 healthy non-offenders also had MRI scans.
The psychopaths had less grey matter in the anterior rostral prefrontal cortex and temporal poles of the brain when compared with other violent offenders and the healthy men.
These areas of the brain are important for processing emotions, fear, and social skills.
