No Lie MRI No Lie MRI is a San Diego-based company offering state- of-the-art brain-scan lie detection services, using a technology called functional magnetic resonance imaging (or FMRI). No Lie MRI believes that neuroscience-and specifically, fMRI technology-will reshape forensic science and courtroom pro- cedures. Old-fashioned polygraph lie detector tests are only moderately accurate; with fMRI technology, you can essentially peer inside a person's mind and see what he or she is thinking You can "see" who is telling the truth...
