Nora D. Volkow, MD, director of the National Institute of Drug Abuse, conducted a recent study with colleagues, placing cell phones on the left and right ears of 47 healthy participants. Using a positron emission tomography scan (enables physicians to study metabolic activity of the body in a pictorial manner) to measure brain glucose metabolism twice, once with the right cell phone activated (sound muted) for 50 minutes (“on”) and once with both cell phones deactivated (“off”).
Overall, whole-brain metabolism did not differ between the on and off conditions; however, metabolism in the region closest to the antenna was significantly higher for the on condition than the off condition.
“The study is important because it documents that the human brain is sensitive to the electromagnetic radiation that is emitted by cell phones,” Dr. Volkow told the New York Times. “It also highlights the importance of doing studies to address the question of whether there are – or are not – long lasting consequences of repeated stimulation, of getting exposed over 5, 10, or 15 years.”
