    • BRAIN FINGERPRINTING

    • INTRODUCTION
      • It was developed and patented in 1995 by Dr. Lawrence A. Farwell.
      • It is based on the theory that throughout any action, the brain plans, records, and executes all of the actions.
    • How it differentiate
      • 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.
      NOT GUILTY
      GUILTY
    • TECHNIQUE
      • P300 or MERMER i.e. Memory and Encoding Related Multifaceted Electroencephalographic Response is emitted from an individual’s brain beginning approximately 300 milliseconds after it is confronted with a stimulus of special significance.
    • What is P300??
      A MERMER is a part of the brainwave observed in response to familiar information.
      • It incorporates the following procedure:
      • The person to be tested wears a special headband with electronic sensors that measure the EEG from several locations on the scalp.
      • The subject views stimuli consisting of words, phrases, or pictures presented on a computer screen. Stimuli are of three types:
      • “ irrelevant” stimuli that are irrelevant to the investigated situation and to the test subject,
      • “ target” stimuli that are relevant to the investigated situation and are known to the subject,
      • “ probe” stimuli that are relevant to the investigated situation and that the subject denies knowing.
    • Computer Controlled
      The entire brain fingerprinting system is under computer controlled .
    • ELECTROENCEPHALOGRAPHY
      Instruments used in EEG
    • THE FANTASTIC FOUR!!!
      Investigation
      Interview
      Scientific Testing
      Adjudication
    • Case Study
    • Background of Terry Harrington case
      On the morning of July 22,1977 John Schweer a retired police officer who was working as a security guard was found dead.
      Terry was arrested.
    • The test and result
      • On April 18 and April 28,2000 Dr Lawrence conducted Brain Fingerprinting test on Terry
      • There was a two phase test..
      And the test result was surprising!!!
    • Y-axis: voltage in microvolts at the scalp
      X-axis: time in milliseconds (msec).
      Terry’s Brain waves
      (Scenario of the Murder case)
      ( Scenario of the concert)
    • Applications
      Medical Field
      Counter Terrorism
      Advertising field
    • LIMITATIONS
      • It does not detect how that information got there. .
      • Brain fingerprinting detects only information..
      • Where the suspect knows everything that the investigators can ask..
    • Conclusion
