As "Prospects of fMRI as a Lie Detector" [9] states, fMRIs use electromagnets to create pulse sequences in the cells of the brain. The fMRI scanner then detects the different pulses and fields that are used to distinguish tissue structures and the distinction between layers of the brain, matter type, and the ability to see growths.
Lie detection is an assessment of a verbal statement with the goal to reveal a possible intentional deceit. Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues. [ 1 ]
The subjects were made to view erotic imagery; "homosexual words," as well as an early form of lie detector to measure perspiration and pulse. The so-called machine was supposed to measure the subject's pupil dilation (pupillary response test), in response to the erotic images and words. The crude apparatus was constructed by the RCMP's ...

Brain fingerprinting (BF) is a lie detection technique which uses brain waves from a electroencephalography (EEG) to determine whether specific information is stored in the subject's cognitive memory. It was invented by Larry Farwell, a Harvard-graduated neuroscientist, and published in 1995. [1]
Truth-default theory (TDT) is a communication theory which predicts and explains the use of veracity and deception detection in humans. It was developed upon the discovery of the veracity effect - whereby the proportion of truths versus lies presented in a judgement study on deception will drive accuracy rates.
A polygraph, popularly referred to as a lie detector, measures and records several physiological indices such as blood pressure, pulse, respiration, and skin conductivity while the subject is asked and answers a series of questions. [11] The polygraph is currently being used in 19 of 50 states in the US.
The most influential was from the writings of Fred E. Inbau from 1942, entitled Lie Detection and Criminal Interrogation. For the third edition in 1953, Inbau invited John Reid as co-author, for a new section on so-called lie detector techniques, such as the "control question". [6]
