In the past few years there have been major terrorist attacks around the globe in developing as well as developed nations. Since then scientists have been pushing hard to come up with a viable alternative for a polygraph test, which at times is rendered useless in revealing concealed information from terrorism suspects. A series of test conducted in the Northwestern lab under J. Peter Rosenfeld (professor psychology in Northwestern's Weinberg College of Arts & Sciences) and his team seems to be the concrete solution in unearthing secret information from stubborn terrorists. The test is about measuring P300 brain waves via electrodes that are attached to the scalp of the test subjects in the lab.
