Cell Phone Use Tied To Changes In Brain Activity 191

Takichi writes "The New York Times is reporting on research linking cell phone use and increased metabolism, with high statistical significance, in the areas of the brain close to the antenna. The study was led by Dr. Nora D. Volkow, director of the National Institute on Drug Abuse, and is published (abstract) in the Journal of the American Medical Association. The impact, good or bad, of the increased stimulation is speculative, but this research shows there is a direct relationship between cell phone signals and the brain that warrants further study."

    It doesn't look like they even used a control group of people doing nothing, people just talking, people talking with the phone on the other side of their head, etc. From the pics all you can tell is that basically a lot of the brain is more active after an hour on the phone, not just the spot next to the antenna. Why are researchers so clueless?

    They were quite deliberate to point out that they used a phone with the antenna in the mouthpiece, so that it would be separated from sources of heat, and that the the increased consumption of glucose was measured in regions near the antenna, and not so much near sources of heat. They claimed this was a significant point because the FDA's current position is that heat is entirely responsible for all reactions that have yet been measured. (Disclaimer: I'm just repeating stuff from articles about it--I didn't read the actual study.)

    >>>It doesn't look like they even used a control group of people doing nothing

    Yes they did.

    >>>people just talking

    Yes they did.

    >>>people talking with the phone on the other side of their head

    Yes they did.
    It helps if you actually READ the article, since the researchers tested the phone on both sides of the head, with the phone turned off, and with the phone turned on, and observed the brain only reactived with the phone turned on (and on whichever side it was located).

    >>>Why are researchers so clueless?

    They are not.
    You however are.
    Sorry but you posted the post, and I'm just responding in kind.

    Yeah, I might one day learn to RTFA properly. Still, they only tested with the phone on the right side switched on, they didn't do the left. Considering it was far more than just the part near the antennae that was active after the hour with the phone on, I think it would have been better to test both sides, maybe even try the phone at the front too.
