Brain Fingerprinting

Brain Fingerprinting

• Dr. Lawrence A. Farewell
• Presented by
• Tonya Slager

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.

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

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)

• 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

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.

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

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
