P300 lie detector
Life Science / Society / Technology

A lie detector designed to analyze P300 brain waves, which are given off when, among other situations, a person recognizes a familiar object. On Earth, the use of this lie detector along with brain imaging techniques such as MRI has become an important form of evidence at legal trials. Science has now unlocked many of the previously unsolved mysteries of the human brain, with lawyers taking a more physiological approach to cases as a result.
