It is a test that maps the brain to reveal 'guilty knowledge.' The brain-mapping test is done to interpret the behaviour of the suspect and corroborate the investigating officers' observation and the suspect's statements. During the tests, forensic experts apply unique technologies to find out if a suspect's brain recognises things from the crime scene that an innocent suspect would have no knowledge of. In a nutshell, experts say the brain fingerprinting test -- as the brain-mapping test is also called -- matches information stored in the brain with information from the crime scene. Studies have shown that an innocent suspect's brain would not have stored or recorded certain information, which an actual perpetrator's brain would have stored. 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 .

Electrodes are attached to head . it can detect which part of the brain is activated while replying to the question. any part of brain will be activated only if any information is stored and that activity will be detected and recorded . investigators carefully design questions mixing info about him and what they want to know about . if he has nothing stored in the brain about the question there will not be any activity detected . if he has , it will be detected. from this they analyze the truth about what he says . for example if he was ever in the crime scene any question about will it activate his brain storing the event . without his answer we now that he is aware of the scene . this process is known as brain mapping . this will help in finding whether whatever he has been saying is corroborated by brain maping as fact or not . it will not help find the truth from him .Answered by RAMASWAMY VENKATESH, 01 Nov '08 12:33 pm
