A cellular phone’s antenna emits the electromagnetic radiation, and that ratiation appears to activate close by regions of the brain to high levels, according to a study published yesterday in the Journal of the American Medical Assn. This study will likely spark new concerns about the health risks of wireless devices.
Providing solid evidence, this early study, led by a known neuroscientist at the National Institutes of Health, shows that cellphone use has certain effects on brain activity, and also suggests that the human’s passionate attachment to cellphones may be altering the way we think and behave in subtle ways.
Researchers were able to conduct experiments inside the brains of 47 healthy volunteers using positron emission tomography, known as PET scanning, to measure the location and timing of brain activity by discovering signs that cells were consuming energy. They found that despite official skepticism that cellphones’ electromagnetic energy exerts any influence on nearby cells — including statements issued by the Food and Drug Administration — it clearly does..
Effects could be diferrent, depending upon the location of a cellphone’s antenna, the frequency on which it operates, and how long somebody uses the device.
At the same time study does not suggest is that mobile devices use contributes to the development of brain cancers.
