"A new forensic tool is helping officers access a suspect's mind to determine what information is indeed stored in the brain.
This new innovation, Brain Fingerprinting, is able to determine whether a person has certain information stored in his memory - such as a criminal act. By reading a specific brain response - called a P300 MERMER (Memory and Encoding Related Multi-facet Electronic Response), which the creator of Brain Fingerprinting Dr. Lawrence Farwell discovered - this innovation has played an integral role in freeing an innocent man from jail and securing a confession to an unsolved murder (see Page 98). Implemented in hundreds of other cases, Brain Fingerprinting is emerging as a powerful and highly accurate forensic tool. "
