Pathological Liars

I DEMAND an immediate MRI of the Presidents brain.

From HealthCentral's web site:

FRIDAY, Sept. 30 (HealthDay News) -- Looking into the brains of people who habitually cheat and lie, neuroscientists have found abnormalities in the area that controls higher thinking.

Pathological liars have less gray matter and more white matter in their prefrontal cortex, according to a report in the October issue of the British Journal of Psychiatry. Gray matter consists of the cells that do the thinking, while white matter consists of the cells that connect them.
