Wired News: Think Away the Pain: "The researchers asked people in pain to try to control a pain-regulating region of the brain by watching activity in that area from inside a real-time functional magnetic resonance imaging, or fMRI, machine. Initial results showed subjects could reduce their pain, some quite dramatically.
It's the first evidence that humans can take control of a specific region of the brain, and thereby decrease pain, said Stanford professor Sean Mackey, who co-wrote the paper, which was published last week in Proceedings of the National Academy of Sciences."
