Could an MRI be Used as a Lie Detector Test?

When you think about the traditional lie detector test, you probably imagine the machines that you've seen on your favorite late night crime dramas. These tests monitor various changes in the body in an attempt to tell if someone is lying. They are considered to be a good indicator of whether or not someone is telling the truth, but they aren't considered to be scientifically accurate. In fact, despite being seen regularly in crime dramas, these lie detector tests aren't admissable into courts as evidence. Perhaps it's time for more advanced technology for detecting lies. Recent discoveries made by a neuroscientist at The University of Pennsylvania suggest than MRI scans might be this more advanced technology. In doing research into the lying impulses of children with ADD, Dr. Daniel Langleben discovered that the functional MRI (fMRI) might be capable of determining that a lie is taking place as it occurs.
"The key point is that you need to exercise a system that is in charge of regulating and controlling your behavior when you lie more than when you just say the truth," Langleben said. "Three areas of the brain generally become more active during deception: the anterior cingulated cortex, the dorsal lateral prefrontal cortex and the parietal cortex."
That scientific jargon basically say that there are three parts of the brain that begin working when you lie. An MRI scan might be able to measure those parts of the brain to identify such changes. This scientific information has been picked up by the sales community which is already trying to promote such technology as the No Lie MRI. In truth, a little more research probably needs to go into studying the changes of the brain that occur during lying. Additionally, we would need to look at the potential consequences of the MRI when used for this purpose. But it's an interesting proposition to consider for the future. If nothing else, it would make a great addition to a new late night crime drama. photo link
