NIH/JAMA Study Shows Cell Phone Increases Brain Activity

In what is probably the most respected study on cell phones’ effects on brain activity to date, National Institutes of Health (NIH) researchers have concluded that cell phones definitely speed up metabolic activity in the brain.  47 participants underwent two tests with one cell phone strapped to the left ear and another to the right ear.  In one test, a 50-minute PET scan (measures metabolic activity in the brain) was performed with the right cell phone turned on.  And in the other test, a PET scan was performed with both cell phones turned off.

The researchers discovered that were significant increases in cellular activity and glucose (the brain’s preferred energy source) metabolism in the region of the brain where the cell phone was turned on.  No assertions were made regarding long term effects, links to cancer or any other clinical diagnosis.  The study was published in a recent issue of the Journal of the American Medical Association.

I’m sure the telecommunication lobbyists in DC don’t care for this study.  Personally, I use my speaker phone every chance I get.  And I don’t carry it on my person unless I absolutely have to and once I reach my destination, I put it on a table/desk until it’s time for me to leave.  There’s no need to subject your cells to all that electromagnetic activity, especially since long term effects are not known.
