A new study has been released from the National Institute of Health (NIH) that proves that extended cellphone use does cause increased brain activity. The researchers, used positron emission tomography scans (PET) to quantify glucose metabolism in the brain. Forty-seven participants took part in the testing. A cell phone was placed at each ear. While one fifty minute scan took place, the cellphones remained in an off state. During the second fifty minute scan, the cell phone at the right side received a call that emitted a prerecorded message. During both scans, when the phones were on or off, there was a 7 percent increase in glucose metabolism at the area of the brain closet to the cell phone antenna.
