 Good review of the issues. Regardless of current legal acceptability of fMRI data in the courts, the use of neuroimaging techniques for investigation will expand. In addition to the companies you mentioned, Cognitive Engineering, LLC (www.Cognitive-Eng.org) uses MRI for truth / deception. CogEng differs in its approach by also applying neuroimaging for face recognition, validating cognitive impairment, demonstrating the sensation of pain, and searching for signals of intent. Neuroimaging technology is very robust, and its use outside of the courts will certainly continue to grow.

False deception

 As reguards the effect of stress, a close friend registered a deceptive answer on a "routine" polygraph exam at work. Fortunately, his boss set up a scenario that demonstrated to the polyrapher that my friends fear of not being believed was responsible for the stress being read as deception. That kind of stress cannot be duplicated in the "control" questions I have had prior to a polygraph. I doubt the fMRI would be able to differentiate the sources for stress associated with deception.
