Cell phone use ups brain activity according to a new study

Cell phones may boost brain metabolism

Talking on your cell phone alters brain activity. A new study finds a link between cell phone use and brain activity.

Researchers say radiation emitted from just 50 minutes on a cell phone increases the activity of brain cells.

However, the National Institutes of Health say the effects of this brain activity are unknown.

They're calling for more study on this issue.

The trade group representing the wireless industry says cell phone use has never been found to be a health threat.
