Brain Fingerprinting is based on the principle that the brain is central to all human acts. In a criminal act, there may or may not be many kinds of peripheral evidence, but the brain is always there, planning, executing, and recording the crime. The fundamental difference between a perpetrator and a falsely accused, innocent person is that the perpetrator, having committed the crime, has the details of the crime stored in his brain, and the innocent suspect does not. This is what Brain Fingerprinting detects scientifically.



When a crime is committed, a record is stored in the brain of the perpetrator. Brain Fingerprinting provides a means to objectively and scientifically connect evidence from the crime scene with evidence stored in the brain. (This is similar to the process of connecting DNA samples from the perpetrator with biological evidence found at the scene of the crime; only the evidence evaluated by Brain Fingerprinting is evidence stored in the brain.) Brain Fingerprinting measures electrical brain activity in response to crime-relevant words or pictures presented on a computer screen, and reveals a brain MERMER (memory and encoding related multifaceted electroencephalographic response) when, and only when, the evidence stored in the brain matches the evidence from the crime scene. Thus, the guilty can be identified and the innocent can be cleared in an accurate, scientific, objective, non-invasive, non-stressful, and non-testimonial manner


The procedure used is similar to the Guilty Knowledge Test; a series of words, sounds, or pictures are presented via computer to the subject for a fraction of a second each. Each of these stimuli are organised by the test-giver to be a “Target,” “Irrelevant,” or a “Probe.” The Target stimuli are chosen to be relevant information to the tested subject, and are used to establish a baseline brain response for information that is significant to the subject being tested. The subject is instructed to press on button for Targets, and another button for all other stimuli. Most of the non-Target stimuli are Irrelevant, and are totally unrelated to the situation that the subject is being tested for. The Irrelevant stimuli do not elicit a MERMER, and so establish a baseline brain response for information that is insignificant to the subject in this context. Some of the non-Target are relevant to the situation that the subject is being tested for. These stimuli, Probes, are relevant to the test, and are significant to the subject, and will elicit a MERMER, signifying that the subject has understood that stimuli to be significant. A subject lacking this information in their brain, the response to the Probe stimulus will be indistinguishable from the irrelevant stimulus. This response does not elicit a MERMER, indicating that the information is absent from their mind. Note that there does not have to be an emotional response of any kind to the stimuli- this test is entirely reliant upon recognition response to the stimuli, and relies upon a difference in recognition- hence the association with the Oddball effect


In fingerprinting and DNA fingerprinting, evidence recognized and collected at the crime scene, and preserved properly until a suspect is apprehended, is scientifically compared with evidence on the person of the suspect to detect a match that would place the suspect at the crime scene. Brain Fingerprinting works similarly, except that the evidence collected both at the crime scene and on the person of the suspect (i.e., in the brain as revealed by electrical brain responses) is informational evidence rather than physical evidence. There are four stages to Brain Fingerprinting, which...
