The Brain May Be the Key to Criminality

The brains of criminals are biologically different from those of the general population, according to new research.

In one study, researchers scanned the brains of 21 people with anti-social personality disorder, a condition that often leaves people with no sense of right or wrong.  The scans showed certain portions of the brains were smaller on average for those with the disorder than those without.

Other studies showed deformations and smaller overall brain sizes in those with severe anti-social personality disorder. These and other studies were recently covered in a story by  Foxnews.com.

Researchers say that many of these differences can be spotted in the brains of children who are very young, but they also say the traits are not  fixed but can be corrected.
