Polygraph tests rely on the hypothesis that a subject's body yields physiologically different symptoms if he or she is lying. When a polygraph test is administered, a mechanical apparatus records the subject's physiological changes, and the polygrapher conducting the examination interprets the data. Polygraph results factor into choices ranging from indictment determinations to employment decisions. While other segments of society use polygraph results, courts remain reluctant to admit them. Although only two federal circuits employ common law bans against polygraph evidence, district courts in every circuit consistently reject polygraph evidence. Similarly, many state courts have excluded polygraph evidence for all purposes. Unfortunately, many of these courts can only exclude polygrap...

The attorney for embattled Senate Majority Leader Scott Bundgaard, who has been under political pressure to relinquish his leadership position after being involved in a domestic violence incident Feb. 25, today released the results of a polygraph test that shows he is telling the truth. In the three-question exam, Bundgaard said he did not touch Aubry Ballard with the intention of harming her during a physical altercation on the side of the freeway, nor did he claim legislative immunity when he was detained by the police at the scene. He also said he told the police that he had had to take his handgun from Ballard during the fracas.

While the earliest reliable noninvasive method, electroencephalography (EEG), used electrical signals to localize and quantify brain activity, measures of metabolic activity using positron emission tomography (PET) and single photon emission computed tomography (SPECT) followed a few decades later in the 1960s.7 EEG studies had exceptional benefits for revealing cognitive processing on the subsecond level, localizing epileptogenic foci, and monitoring patients with epilepsy. Penfield's corticography work enabled even more accurate measurements from recordings made directly from the cortex during neurosurgery.8 PET and SPECT have been used widely in basic research studies of neurotransmission and protein synthesis, further advancing our knowledge of neurodegenerative disorders, affectiv...
