Definition from Nolo’s Plain-English Law Dictionary
A lie detector device that tests a person's physiological response (for example, changes in blood pressure and respiration) to questionning. The test's reliability is a matter of ongoing controversy, and in most U.S. states polygraph test results are not admissible in court.
