What cell phone use does to the brain

There's a new study out that shows the impact of cell phones on your brain.

The question is, what would happen to the brain as a result of the increased activity of brain cells?

Dr. Rose Lai with NY Presbyterian is an expert in brain cancer.

"We really don't know. We really don't know what the consequence is when a brief exposure to cell phones cause nerve cells to fire more often," she said.

It's not cancer that Dr. Lai thought of first. Activated brain cells can be a sign of epilepsy.

"It certainly jumped ionto my mind...butt...the person developing epilepsy if cell phone use is prolonged," adds Dr. Lai.

Dr. Lai adds she knows of no known link between cell phone and epilepsy, and increasing use of texting keeps phones away from the brain. Some simple advice.

"Just protect yourself by using an earpiece and not having the cell phone directly over your ear," she adds.

One other issue with the study that Dr. Lai pointed out is that it's not clear whether the brain cells stay active for minutes or hours after phone use stops.

She also warns that in kids where the brain is still growing, the effect of prolonged cell phone use is unknown.
