A German neurologist claims to have found the area of the brain where evil lurks in killers, rapists and robbers.
Bremen scientist Dr Gerhard Roth says the ‘evil patch’ lies in the brain’s central lobe and shows up as a dark mass on X-rays.
He discovered it when investigating violent convicted offenders over the years for German government studies.
‘We showed these people short films and measured their brain waves,’ he said.
‘Whenever there were brutal and squalid scenes the subjects showed no emotions. In the areas of the brain where we create compassion and sorrow, nothing happened.’
The dark mass at the front of the brain, he says, appears in all scans of people with records for criminal violence.
