    Polygraphs are systems that detect changes in physical response to questions that are posed to the person being interrogated or interviewed. In addition
    to the usual set of measured points of consideration there is now two other things to monitor in polygraph examinations. Those are voice stress analysis and Functional MRI. VSA detects truth by detecting changes in speech in all its many changes that go on when a person is trying to keep something secret. It has become commericialized with the PSE-VSA --- The Psychological Stress Evaluator Voice Stress Analysis. As for fMRI they look at the part of the brain that lights up after being asked a question, while they respond to that question. If only one set of areas lights up then the person is probably not lying, however if the second set of regions lights up then a person is trying to suppress the truth. In the first scenario a person is just going about normal thought processes that reflect themselves in "normal" brainwaves. In the second scenario there is a differnt area that lights up whenever the brain's function of suppressing revealation of truth or having high anxiety occurs. So lying doesn't work. Bust what does? The absence of response is the best way to avoid getting in trouble. If you do not consent you are
    highly likely to avoid this whole mess.
