London, Aug 5 - Biological differences in the brain may explain why some people turn into psychopaths, says a new study.

The research, conducted by Declan Murphy, along with Michael Craig and Marco Catani, at King's College, examined the brain biology of psychopaths with convictions that included attempted murder, manslaughter, multiple rape etc.

Using a powerful imaging technique (DT-MRI) researchers highlighted biological differences in the brain which may underpin these types of behaviour and provide a more comprehensive understanding of criminal psychopathy.

'If replicated by larger studies, the significance of these findings cannot be underestimated.
