    From BBC. The site shows the scan with the parts of the brain deactivated by pain. Title of the article is:

    Acupuncture 'deactivates brain'

    Acupuncture caused brain activity over and above a simple skin prick
    Acupuncture works by deactivating the area of the brain governing pain, a TV show will claim.
    Tuesday's programme - the first of three on complementary medicine - will show researchers carrying out brain scans on people having acupuncture.

    The BBC Two show will also feature heart surgery done using acupuncture instead of a general anaesthetic.

    The patient is conscious during the operation in China, but she was given sedatives and a local anaesthetic.

    In Alternative Medicine: The Evidence, volunteers are subjected to deep needling, which involves needles being inserted 1cm into the back of the hand at well-known acupuncture points.

    A control group undergoes superficial needling with needles placed only 1mm in.

    Sensation

    The needles are then twiddled until the participants feel a dull, achy or tingling sensation. For those in the deep needling group this stimulates the nervous system.

    During these two procedures, the volunteers underwent brain scans to see what, if any, effect there was in the brain.

    The team, including leading scientists from University College London, Southampton University and the University of York, found the superficial needling resulted in activation of the motor areas of the cortex, a normal reaction to pain.

    But with deep needling, the limbic system, part of the pain matrix, is deactivated.

    The finding was surprising because experts had always assumed acupuncture activates the brain in someway.

    Professor Sykes said: "The pain matrix is involved in the perception of pain - it helps someone decide whether something is painful or not, so it could be that acupuncture in some ways changes a person's pain perception.

    "We have found something quite unexpected - that acupuncture is having a measurable effect on the human brain.

    "We are not suggesting that it should be used during surgery, although it is in China, but just that it acts as a pain relief and should be taken seriously."

    Professor Tony Wildsmith, a pain relief expert at the University of Dundee, said he thought the findings were possible.

    But he added: "The thing about acupuncture is that it does not work on everyone. It is more likely to be effective if you believe it.

    "I think it is a psychological manipulation technique, a distraction. We are not going to get to the stage where this could be used instead of a general anaesthetic."

    Thanks for posting this. I had a very interesting experience with my acupuncture today that ties into this!

    We were doing a point in my foot that we had done before, but this time, I got a weird pulse of electrical sensation when we were placing the needle. It wasn't till my acupuncturist went to take the needle out 15 minutes or so later that we realised that my foot was NUMB, and my leg partly numb from the knee down. Once I got moving, it felt normal in a few minutes, without any "pins and needles" feeling like when a limb falls asleep. It had felt exactly like when your cheek is still numb from the dentist!

    I've gotten acupuncture for several months now in many places on my body, and never had this happen before. The acupuncturist says she must have hit a nerve just right or something (I have a terrible memory). I couldn't help thinking at the time, "Wow! This has some possibilities!"

    Since neither of us were trying for this numbing effect or expecting it, I would say that it's not a "psychological manipulation technique, a distraction" as Proffessor Wildsmith says, but that needles placed a certain way really do block out sensations.

    the first time i got needled on the bottom of my foot (great for drawing heat out of the head!), i had the same experience, my foot and ankle went numb.
