First evidence of brain abnormalities found in pathological liars

The USC study shows structural differences in the area of the brain that enables most people to feel remorse
A University of Southern California study has found the first proof of structural brain abnormalities in people who habitually lie, cheat and manipulate others.
While previous research has shown that there is heightened activity in the prefrontal cortex � the area of the brain that enables most people to feel remorse or learn moral behavior � when normal people lie, this is the first study to provide evidence of structural differences in that area among pathological liars.
