Brain Fingerprinting is a scientific technique that detects whether specific information about a crime is stored in a suspect's brain. It presents words, pictures, or sounds related to the crime to the subject while measuring brainwave responses, particularly the P300 response emitted only when the information is familiar. Two types of stimuli are used: probes related to the crime details and targets the subject is told to respond to. Case studies on government agents and real crimes found the technique was 100% accurate in determining who had knowledge of the crime details stored in their brain.

2. The fundamental difference between the
perpetrator of a crime and an innocent
person is that the perpetrator, having
committed the crime, has the details of
the crime stored in his memory, and the
innocent suspect does not.
This is what Brain Fingerprinting testing
detects scientifically, the presence or
absence of specific information.

3. Defining Brain Fingerprinting
 Scientific technique to determine whether or not specific
information is stored in an individual's brain
 Relevant words, pictures or sounds are presented to a
subject by a computer in a series with stimuli
 The brainwave responses measured using a patented
headband equipped with EEG sensors
 P300- Specific, measurable brain response
 emitted by the brain of a subject who has the relevant
information stored in his brain

5. How Does it Work?
 measurements are recorded in fractions of a
second after the stimulus is presented, before
the subject is able to formulate or control a
response
 Dr. Farwell discovered that the P300 was one
aspect of a larger brain-wave response that he
named and patented, a MERMER (memory and
encoding related multifaceted
electroencephalographic response)

6.  Brain responses were recorded from the
midline frontal, central, and parietal scalp
locations, referenced to linked mastoids
(behind the ear), and from a location on
the forehead to track eye movements
 At the end of each test, subjects were
given a written list of all stimulus items
and asked to mark each item as
noteworthy, somewhat noteworthy, or
irrelevant – those marked were thrown out

7. Information is absent Information is present

9. The MERMER includes:
1. The P300 -an electrically positive
component maximal at the parietal scalp
site
2. Another, longer latency, electrically
negative subcomponent prominent at the
frontal scalp site
3. Phasic changes in the frequency and
structure of the signal.

10. Types of Stimuli Used
 Probes
 Life-experience related
 Relevant to the investigated event -recognizable and noteworthy only
for the subjects who had participated in the event (MERMER)
 Indistinguishable from the Irrelevants for a subject who is not
knowledgeable about the situation under investigation
 Targets
 Push a button to indicate known image
 Since the relatively rare Targets are singled out in the task being
performed, the Targets are noteworthy for the subject, and each
Target stimulus elicits a MERMER
 Irrelevant Stimuli
 information relevant to the crime that the suspect claims to have no
knowledge of

11. Case Studies
 FBI- new agents 100% accurate
 CIA- 3 experiments
 Pictures rather than verbal cues
 Words/phrases to determine connection
between professionals, their organization, and
known information related to work
 Real-life events including 2 felony crimes
Overall 79 participants with 100% accuracy
