Scientists find liars' brains are different

[sasha031]

A preschooler tells her teacher that her parents are dead -- one of the earliest falsehoods of a pathological liar.

Through the years, the girl's lies have been so profound, so unrelenting, that she has never been able to keep a friend.

Along the way, the young woman, now 19, and who asked not to be identified, pretended to have stomach cancer, countless pregnancies and an abusive boyfriend. Again, all lies. Now, scientists at the University of Southern California may have provided a biological explanation for this kind of lying.

Yaling Yang and colleagues have identified structural differences in the prefrontal regions of the brain in pathological liars. Liars showed a 22 percent increase in the white matter in the brain and a 41 percent reduction in the ratio between gray and white matter. Scientists compared brain scans of people with a history of lying to those of normal people and to those with anti-social personality disorders.

Is there a difference between normal chimps and lying chimps? Just curious.:P

5. Would be interesting to test brains of many pols to the general population

Bet there would be more of one type in the politicians group than the general population.

6. White matter exists where people are born with deficits. So if the person

is dyslexic - they'll get white matter there, auditory retention difficulties - white matter in some compensatory area.

If someone is born a liar - then white matter is the compensation for not being born with full frontal lobes.

Thank god there will be tests. Or are tests. Thank god. We can not just see how a brain is structured - but how a brain compensates for deficites.

Amazing.

Will save lives.
