Now new data from the National Institutes of Health suggesting that cell phone radiation boosts brain activity is poised to stir the debate even further.
Researchers used PET scans to measure brain activity in 47 participants when they had cell phones held to their ears in both off and on but muted positions and found that exposure to an in-use cell phone for more than 50 minutes increased brain activity by about 7 percent in the regions closes to the antenna.
This suggests that while no link has been proven between adverse health effects and cell phone radiation, the human brain is sensitive in some way to the electromagnetic waves coming off of a cell phone.
Whereas past studies have looked at cerebral blood flow to measure changes in brain activity, this study measured the brain's consumption of glucose -- the fuel of the brain -- in order to measure localized activity near the antenna.
