Volney G. Mathison was an American experimenter/hobbyist in early biofeedback, galvanic skin response technology, and psychogalvanometer (lie-detector machine) research in the 1940s and 1950s. He was also a Chiropractor and an author of paranormal and Science Fiction books. Mathison discovered through experiments with early lie-detectors during the 1940s that when the subject was reminded of certain past events, the lie detector needle would fluctuate. Wikipedia
