Video: This is Your Brain on Cell Phone

Breaking news: Cell phones may or may not harm your brain.


Do you want to know what happens to your brain when you talk on your cell phone? This Wall Street Journal video discusses new research in The Journal of American Medical Association. The Wall Street Journals' Shirley Wang says:

There is evidence that brain activity increases when you are on your cell phone.. We don't know if it's good or bad activity or if it's a safety issue or not. So basically, the study doesn't say much other than cell phones increase brain activity. Researchers say it's true, cell phones do create some sensitivity of the brain, but we need more research to know if it's actually going to be harmful or not.


The New York Times today also reports on the findings:

Researchers from the National Institutes of Health have found that less than an hour of cellphone use can speed up brain activity in the area closest to the phone antenna, raising new questions about the health effects of low levels of radiation emitted from cellphones.


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.
