Wired News: You Can't Hide Your Lyin' Brain

Wired News: You Can't Hide Your Lyin' Brain: "CHARLESTON, South Carolina -- A scientist at the Medical University of South Carolina has found that magnetic resonance imaging machines also can serve as lie detectors.

That compares with polygraphs that range from 80 percent to "no better than chance" at finding the truth, George said.

The study found MRI machines, which are used to take images of the brain, are more than 90 percent accurate at detecting deception, said Dr. Mark George, a distinguished professor of psychiatry, radiology and neurosciences."
