A new study has found a connection between injuries in certain areas of the brain and criminal behaviour.

High profile cases involving personality changes and criminality following brain injuries have highlighted this area of research in recent years.

However, there is still plenty of speculation around the role brain injuries play in instigating criminal behaviour.

They applied this technique to a selection of cases in which people had undertaken criminal behaviour following brain injury.
