Is there a part of the brain which is active when telling lies versus the truth? For this reason, fmri is routinely used in basic research as a mainstay method to measure brain function and its data are often triangulated with data from complementary. It's the operator that is accurate (or not, depending on his/her it is possible to use a lie detector, but evidence of guilt is far superior.
