Abstract Brain-scanning machines may soon be capable of discerning rudimentary thoughts and separating fact from fiction. In October 2002 the United States National Research Council damned the polygraph device as a "blunt instrument," of little use in ferreting out criminals, spies and terrorists. The idea of looking directly at brain activity to tell truth from falsehood dates back to when J. Peter Rosenfeld of Northwestern University observed an interesting feature in the electroencephalograph, a chart of the brain's electrical signals as detected on the surface of the skull. Daniel Langleben of the University of Pennsylvania and his colleagues used functional magnetic resonance imaging (fMRI) to scrutinize the brains of subjects acting out a question-and-answer series. Niels Birbaumer of the University of Tübingen in Germany has reported a degree of success in using biofeedback to train patients immobilized by nerve damage to vary their brain waves and so to spell out sentences on a computer screen. But true mind reading must do better, by catching a word or concept exactly as it forms itself in the brain. Marcel A. Just of Carnegie Mellon University claims he has done just that with fMRI, by limiting the concepts to a small number and keeping them very simple
