A new study from the National Institutes of Health suggests that using cell phones can change the way our brains behave, though it remains unclear whether these changes can be harmful. The study, published yesterday in the Journal of the American Medical Association, found that just 50 minutes of cell phone use can noticeably speed up brain activity in the region closest to the phone's antenna. While overall brain metabolism didn't change when exposed to wireless radiation, activity in the area next to the antenna spiked by 7-percent. Dr. Nora Volkow, who led the study, told Reuters that the findings are significant because they demonstrate that even weak radiation from cell phones can alter the brain's metabolism. But she added that it's still too early to tell whether or not cell phones pose a tangible neurological risk, emphasizing that the results do "not in any way indicate that" cell phones can cause cancer.
