Liars Have Stronger Brains

Dr. Scott Faro, director of the Functional Brain Imaging Center at Temple University School of Medicine in Philadelphia, and his team argue that liars' brains usually have to work much harder in order to create a lies indistinguishable from a truth. Perhaps, you've already knew it from a personal experience.

Faro and colleagues tested 10 volunteers. Six of them were asked to shoot a toy gun and then lie and say they didn't do it. Three others who watched told the truth about what happened. One volunteer dropped out of the study.

While giving their "testimony," the volunteers were hooked up to a conventional polygraph and also had their brain activity imaged using fMRI, which uses a strong magnet to provide a real-time picture of brain activity.

There were clear differences between the liars and the truth tellers, Faro's team told a meeting in Chicago of the Radiological Society of North America.
