The sentence of death row inmate Jimmy Ray Slaughter is being appealed, based on a new type of lie detector: the brain fingerprint.
Graham Inglis explains the process in Phenomena magazine. If you’re shown an image that you haven’t seen before, your brain stores it away as a new memory that can be detected on a brain scanner. If you HAVE seen it before, that reaction can also be “read.” Since if he’s never seen the crime scene, a suspect can’t be guilty of the crime, the suspect is shown crime scene images while investigators look at which parts of his brain light up. Just as in a conventional lineup of suspects, other images are mixed in with the crime scene photos while they flash by on a computer screen.
