crime investigation -brain mapping a new phenomenon

this technique is a relatively new phenomenon in india,and has an extremely high success rate.it is again performed in a controlled environment. no chemicals are used . Prof. C R Mukundan,former head of the department of mental health and neurosciences,banglore , explains how this technique works.when a person performs an act in this case , a gruesome murder-the event is recorded in the brain is something called experential knowledge. by connecting electrodes to the head, brain signature mapping records the electrical activity and oscillations in the brain as a response to certain images he is shown. and can a person lie during such a procedure? unlike other process where questions are put to the subject,here no questions are asked,indeed,there is no need for verbal responses from the subject either ,so the issue of telling a lie doesnot arise.it's all do with the electrical impulses in the brain directly, and that's not something a person can control.
