NEW YORK (CBS 2) — For many people, cell phones serve as the ultimate accessory, but what about the danger so many have long suspected? Do the radio frequency signals emitted from cell phones affect our brain?READ MORE: Former Gov. Andrew Cuomo Charged With Misdemeanor Forcible Touching
1010 WINS’ John Montone with Dr. Volkow who says researchers have a responsibility to investigate whether there are long-lasting consequences of glucose increases in the brain
A study published in this week’s Journal of the American Medical Association attempted to find answers to that question. Over the course of one year, researchers followed 47 healthy people, who had cell phones placed on their left and right ears. One phone was muted for 50 minutes, while the other was completely off.
Researchers used pet scans to monitor the amount of glucose in the brain.
“It’s a very sensitive marker to indicate if there are changes in brain activity that may be driven by a given stimulus which in this case was the cell phone,” Dr. Nora Volkow of the National Institute on Drug Abuse told CBS 2’s Derricke Dennis.READ MORE: 'Survivor' Contestant Michelle Yi Describes Frightening Santa Monica Assault
The results of the study revealed that 50 minutes worth of exposure to an active cell phone showed glucose increases in the brain. The glucose is an indication the brain was being activated by cell phone radio frequencies.

“Even though the radio frequencies are very weak, they are able to activate the human brain — to have an effect,” Volkow said.
Going hands-free could be more beneficial to one’s health. Radio signals from cell phones drop off dramatically with even a little distance from the head.
Still researchers admitted — they don’t yet know what the brain activation in the study meant, and cannot say whether cell phones caused cancer because more research was needed.
