Can Phone change the activity of brain cells?

Calling for 50 minutes with the phone can change the activity of brain cells, especially in the brain that has a position closest to the antenna.
But it is not yet certain whether the changes in activity that causes damage to the brain. Thus the results of studies of scientists at the National Institutes.

They added that this study could not confirm whether the use of mobile phones really cause brain cancer.

The study is expected to observe the reaction of the brain to electromagnetic waves generated cell phone signals.

Dr. Volkow also said he was surprised to see a weak electromagnetic radiation from mobile phones is enough to affect brain activity. But he still asserted that when the invention is not able to answer the phone link to cancer.
