Abstract

Abstract: When a person experiences a familiar stimulus, the brain emits a unique brain wave pattern, which is known as brain fingerprinting. The use of functional magnetic resonance imaging in lie detection stems from studies that reveal that people who are asked to lie have distinct patterns of brain activity than people who are telling the truth. The use of such evidence in courts is examined in detail. The author concludes that neither approach has adequate evidence of accuracy in identifying fraud to be used in court at this time. A new lie detector has been developed in the field of criminology in the United States of America. This is referred to as "brain fingerprinting." This innovation is said to be the greatest lie detector on the market right now. When a person experiences a familiar stimulus, the brain emits a unique brain wave pattern, which is known as brain fingerprinting. In order to identify lies, functional magnetic resonance imaging is used. This innovation is believed to be the finest lie detector accessible to date, detecting even slick crooks who easily pass the polygraph exam (the traditional lie detector test). The new technology uses brain waves to determine whether or not the person being tested remembers the finer details of the incident. According to scientists who are very pleased about the new kid on the block, even if the person voluntarily suppresses the vital knowledge, the brain wave will undoubtedly catch him.
