Study: Cell Phone Use Increases Brain Activity. What’s Not Known Is if that’s Good or Bad

Feb 23, 2011  •  Post A Comment

A new study says that cell phone use can increase brain activity, However, "The researchers, led by Dr. Nora D. Volkow, director of the National Institute on Drug Abuse, urged caution in interpreting the findings because it is not known whether the changes, which were seen in brain scans, have any meaningful effect on a person’s overall health," reports The New York Times.

The article adds, " ‘The study is important because it documents that the human brain is sensitive to the electromagnetic radiation that is emitted by cellphones,’ Dr. Volkow said. ‘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 five, 10 or 15 years.’ "

The article itself is a good read, as are the comments to it, and the responses to the comments by the author of the article, Tara Parker-Pope.
