Another day, another researcher trying to determine whether your cellphone
is slowly killing you. This time it's the National Institute of Health's
neuroscientist Dr. Nora Volkow
who tracked glucose consumption in the brain during prolonged periods of cellphone use.
Volkow points out that her approach attempted to be more comprehensive than previous cellphone studies by using a larger test group, 47 people, and longer rates of cellphone exposure. In her study, Volkow introduced radioactively marked glucose into the test subjects, and then observed how that glucose was used in the brain via PET scan. Her report indicates that the brain did indeed absorb more glucose on the side of the head where the phone was active, a 7% increase in one area.
Now, before you encase your phone in lead, or reject society and flee to the woods, let's let another neuroscientist give us some perspective.
