This document discusses Brain Fingerprinting, a technique developed by Dr. Lawrence Farwell to identify perpetrators of crimes by measuring brain wave responses to crime-relevant stimuli. It works by presenting words/images to a subject wearing an EEG cap and analyzing the MERMER response in the brain, which occurs when the brain recognizes familiar information. The document outlines how Brain Fingerprinting works, its applications in national security, medicine, and advertising, and its invention and testing, concluding it could be a revolutionary criminal investigative tool.
