A new study has found that cell phone use can have high measurable effects on brain activity, confirming fears that the long-term use of mobile phones can cause serious health hazards.

The long-term negative effects of cell phone use on health has been debated and researched but conclusive findings have always evaded the scientific community as cell phone use has too short a history to have solid empirical evidence.

However, the new study, which was published in the Journal of the American Medical Association, shows that electromagnetic radiation emitted by a cell phone antenna can activate the human brain to unusually high levels, the Los Angeles Times reported.

The study was done by a respected neuroscientist at the National Institutes of Health.

“By providing solid evidence that cellphone use has measurable effects on brain activity, it suggests that the nation's passionate attachment to its 300 million cellphones may be altering the way we think and behave in subtle ways,” the Times reported.

There has been no serious finding so far to prove conclusively that a cell phone’s electro magnetic activity can inluence nearby cells. Even the Food and Drug Adminitration has been skeptical of the high health hazard of cell phone, the report shows. However, the new study proves the skeptics wrong.

Researchers peered inside the brains of 47 healthy subjects using positron emission tomography, also known as PET scanning, to measure the location and timing of brain activity by detecting signs that cells were consuming energy. They found that despite official skepticism that cellphones' electromagnetic energy exerts any influence on nearby cells — including statements issued by the Food and Drug Administration — it clearly does.”
