For some time, we have known that a region of the brain known as the prefrontal cortex is linked to violence, though it has been unclear whether particular patterns of activity in that area are, in fact, the cause behind aggression.
The brain’s prefrontal cortex has been linked to the control of aggressive behaviors.
And, studies have suggested that damage to this part of the brain can cause people to become more violent and antisocial.
But it has remained unclear whether deficits in the prefrontal cortex drive violent behavior, or whether such problems — and the behavioral issues — are caused by a third and unknown factor.
