Antisocial behaviors such as stealing, bullying, and lying may have their origins in brain structures.
British and American researchers used MRI scans to compare the brain compositions of those with a history of these behaviors to those without.
They found that antisocial individuals may have thinner cerebral cortices and smaller surface area in some regions of the brain than others.
It's the first robust evidence suggesting that underlying neuro-psychological differences exist in people with persistent antisocial behavior.
UPI reports researchers say the findings may have implications for the way society treats juvenile offenders.
