Cell phone exposure increases brain cell activity
(CNN) -- The radiation emitted after just 50 minutes on a mobile phone increases the activity in brain cells, according to a new government-funded study.
The small study, published in the Journal of American Medical Association, is the first to look specifically at how electromagnetic radiation from cell phones affects glucose metabolism, a normal function, in the brain.
Researchers measured brain activity of 47 healthy adults -- a small but scientifically valid size group for this type of study -- while using a mobile device. The levels were tested when the phone was in use (transmitting radiation) against the head and when against the head but in the off position. Compared with subjects whose phones were turned off, the group whose phones were on had "significantly higher" brain activity in the area closest to the telephone antenna.
Volkow says that since she began working with the National Institutes of Health researching the impact of cell phone radiation, she always uses a wired earpiece when talking on her cell phone.Read more at edition.cnn.com
