Cell Phone Exposure Increases Brain Metabolism – Study

By on Feb 23, 2011 in Cellphone, Health, Science, Technology Comments

According to several international news sites on Tuesday, a recent study revealed that a 50-minute exposure to a cell phone plastered to the ear is enough to alter brain cell activity in the parts of the brain nearest to the antenna. However, it was reported that it is not yet clear if the brain cell activity causes any harm.

“When glucose metabolism goes up, it activates cells. The findings are an indication that exposure to cell phones activate the brain much more easily than we previously thought,” Dr. Nora Volkow, National Institutes of Health neuroscientist and lead study author was quoted saying.

According to Volkow, the findings do not prove that cell phones cause cancer. “This study does not in any way indicate that. What the study does is to show the human brain is sensitive to electromagnetic radiation from cell phone exposures,” Volkow added.

The study found that there is a 7 percent increase in brain metabolism in the region nearest to the cell phone antenna when the phone was on.

Experts were intrigued with the results and recommended further investigation. “Although the biological significance, if any, of increased glucose metabolism from acute cell phone exposure is unknown, the results warrant further investigation,” Henry Lai of the University of Washington, Seattle, and Dr. Lennart Hardell of University Hospital in Orebro, Sweden, wrote in a commentary in Journal of American Medical Association (JAMA).
