Lying Makes The Brain Work Harder

Ant writes "This Wired News article says it seems to take more brain effort to tell a lie than to tell the truth according to functional magnetic resonance imaging (fMRI) scans. Lying caused activity in the frontal part of the brain -- the medial inferior and pre-central areas, as well as the hippocampus and middle temporal regions and the limbic areas. Some of these are involved in emotional responses. During a truthful response, the fMRI showed activation of parts of the brain's frontal lobe, temporal lobe and cingulate gyrus."

      How would you get it out? The MRI I had a couple years ago was done in a machine with a permanent magnet in it.

      Although, they let me play with a 20lb log chain about 15 feet from the machine. I held it up, and it pointed completely horizontal into the machine. I got about 6 inches closer and had to wedge my foot into the table to pull it away. Big magnets are fun, but damn, after that, it really makes one see how dangerous they can be.
