Cell Phone Use Alters Brain Metabolism
The huge increase in the use of cell phones has prompted concern from many physicians because of the specific radio frequencies delivered to the brain as calls are made.
A study entitled "Effects of Cell Phone Radio frequency Signal Exposure on Brain Glucose Metabolism" was published in the February 23, 2011 issue of JAMA (the Journal of the American Medical Association)
Nora D. Volkow, M.D. assembled a team of 9 researcher to study glucose level fluctuations while subjects held 2 cell phones to their head for a total of 50 minutes. During this time, one phone was turned on, and the other wasn't. After collecting the data, they found that the on-off conditions showed no difference in whole-brain metabolism but that there was an increase in brain glucose metabolism in the area of the brain closest to the antennae.
They couldn't say what this meant in terms of the future health/illness of a person, but instead had proven that the cell phone use affects brain glucose metabolism. Let it be noted that brain glucose is the "fuel" for the brain. (Glucose is the "sugar" or "fuel" for the brain.) Does this mean the cell phone requires the brain use energy to protect itself? No one knows!
