There have been many conflicting studies looking at a possible link between cell phone use and brain cancer. A new study looks at a different question.

Does the use of mobile phones increase activity in the brain?

Research in the Journal of the American Medical Association compared brain activity in people when cell phones were on and off.

When the devices were on the report says activity in the brain closest to the antenna was about 7 percent higher.

The conclusion is that the human brain is sensitive to electromagnetic waves from cell phone exposure.

What researchers can't say is whether this increased activity is good, bad or meaningless.
