Brain scans to spot liars

I saw this in the news today and I thought that it was interesting – using MRI scans to observe brain patterns in order to determine if someone is lying or not. It sort of links back to my MSc project on cerebral blood flow patterns in the elderly and how they can be used to detect dementia and neurological changes. It’s a similar principle of detection and so forth :)

At the same time, the I am also aware of expensive these kind of tests are but like the article says, the process needs a lot more work on it before it can be used in a practical setting.
