Brain fingerprinting

From Wikipedia, the free encyclopedia

Brain fingerprinting is a scientific technique which uses electroencephalography (EEG) to determine whether specific information is stored in a subject's brain. The technique consists of measuring and recording a person's electrical brainwaves and brain response when asked questions about a crime, attempting to elicit a "P300 response" that indicates familiarity with the details of the crime.[1] The technique is controversial, unproven[1] and of questionable accuracy.[2] Comparison of brain fingerprinting with polygraphy showed mixed results consistent with "a mix of proven techniques and dangerously exaggerated benefits".[1]
