Narco Analysis And Brain Mapping

The term narcoanalysis was introduced in 1936 for the use of narcotics to induce a trance like state wherein the person is subjected to various queries. Under the influence of the drug, the subject talks freely and is purportedly deprived of his self-control and will power to manipulate his answers. The underlying theory is that a person is able to lie by using his imagination. In the narcoanalysis test, the subject’s imagination is neutralized and reasoning faculty affected by making him semi-conscious. The subject is not in a position to speak up on his own but can answer specific and simple questions. In this state it becomes difficult for him to lie and his answers would be restricted to facts he is already aware of. His answers are spontaneous as a semi-conscious person is unable to manipulate his answers.
