Brain fingerprinting
Larry Farwell says he can tell when you're lying. By using his 'Brain Fingerprinting' technology he can detect details of a crime scene stored in a brain that only the guilty could know.
Farwell measures suspects' brain waves using electroencephalography (EEG) while they look at words or pictures. When they recognise something, their brain sends out a characteristic brain-wave pattern, revealing that they remember that potentially incriminating detail.
