So, they’ve found some measurable effects on the brain of using a cell phone next to the head, but there’s no evidence of harm, apparently:
Exposure to the electromagnetic fields emitted by cell phones excites the brain in a small but measurable way, reveals a new study published in the Annals of Neurology.
…
The researchers
found that cell phone exposure increased cortical brain activity on the left side, where the phone was activated.
…
In this study, the researchers measured how “ready” a subject’s brain was to move his or her thumb.
…
At this point, scientists cannot say if this increased activity is good or bad. The results are too preliminary.
