Liars' Brains Wired Differently

A report I found on Hackenblog; now extracted from the original article:
A USC study has found the first proof of structural brain abnormalities in people who habitually lie, cheat and manipulate others.
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 research, on the other hand, is the first to provide evidence that among pathological liars, structural abnormalities in that area of the brain exists.
When people make moral decisions, they are relying on the prefrontal cortex. When people ask normal people to make moral decisions, we see activation in the front of the brain. The researchers discovered that liars had significantly more white matter and slightly less gray matter in the prefrontal cortex.
More white matter means that part of their brain has more efficient networking, making them more brilliant. Their verbal skills are higher. They have almost got a natural advantage. A deficit in gray matter means they are less likely to care about moral issues or are less likely to be able to process moral issues.
