Cellphone Use Tied to Changes in Brain Activity

Cellphone Use Tied to Changes in Brain Activity
By TARA PARKER-POPE

Researchers from the National Institutes of Health have found that less
than an hour of cellphone use can speed up brain activity in the area
closest to the phone antenna, raising new questions about the health
effects of low levels of radiation emitted from cellphones.

The researchers, led by Dr. Nora D. Volkow, director of the National
Institute on Drug Abuse, urged caution in interpreting the findings
because it is not known whether the changes, which were seen in brain
scans, have any meaningful effect on a person's overall health.

But the study, published Wednesday in The Journal of the American
Medical Association, is among the first and largest to document that the
weak radio-frequency signals from cellphones have the potential to alter
brain activity.

"The study is important because it documents that the human brain is sensitive to the electromagnetic radiation that is emitted by cellphones," Dr. Volkow said. "It also highlights the importance of doing studies to address the question of whether there are — or are not — long-lasting consequences of repeated stimulation, of getting exposed over five, 10 or 15 years."

Although preliminary, the findings are certain to reignite a debate
about the safety of cellphones. A few observational studies have
suggested a link between heavy cellphone use and rare brain tumors, but
the bulk of the available scientific evidence shows no added risk. Major
medical groups have said that cellphones are safe, but some top doctors,
including the former director of the University of Pittsburgh Cancer
Center and prominent neurosurgeons, have urged the use of headsets as a
precaution.
