Cell Phone Use May Have Effect On Brain Activity !

callingUsing a cell phone for 50 minutes may be associated with increased brain glucose metabolism (a marker of brain activity) in the region closest to the phone antenna, but the finding is of unknown clinical significance, according to a new study.The researchers found that whole-brain metabolism did not differ between the on and off conditions. However, there were significant regional effects. Metabolism in the brain region closest to the antenna (orbitofrontal cortex and temporal pole) was significantly higher (approximately 7 percent) for cell phone on than for cell phone off conditions. “The increases were significantly correlated with the estimated electromagnetic field amplitudes both for absolute metabolism and normalized metabolism,” the authors write. “This indicates that the regions expected to have the greater absorption of RF-EMFs from the cell phone exposure were the ones that showed the larger increases in glucose metabolism.”
