Liars' brains 'are not the same'

Habitual liars' brains differ from those of honest people, a study says.
A University of Southern California team studied 49 people and found those known to be pathological liars had up to 26% more white matter than others.

White matter transmits information and grey matter processes it. Having more white matter in the prefrontal cortex may aid lying, the researchers said,

But the British Journal of Psychiatry said there were likely to be more differences in the brains of liars.
