Brain fingerprinting is a
scientific technique which uses
electroencephalography
Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex ...
(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.
The technique is controversial, unproven
and of questionable accuracy.
Comparison of brain fingerprinting with
polygraphy showed mixed results consistent with "a mix of proven techniques and dangerously exaggerated benefits".
