It stands to reason that those little bundles of electromagnetic radiation we call cell phones affect the body somehow, and researchers have confirmed they mess with our brains.

A study published in the Journal of American Medical Association found 50 minutes of cell phone use made subjects’ brain cells more active. The study doesn’t make conclusions as to whether the activity makes you think faster or more effectively, or has some sort of negative effect.

A representative from Environmental Working Group tells CNN the study raises some eyebrows: “It joins the growing list of studies that have raised concerns about cell phone use and the brain,” she said.

Wireless industry group CITA says no research has proven cell phones to be dangerous:

Said a CITA spokesman in a statement:

“The peer-reviewed scientific evidence has overwhelmingly indicated that wireless devices, within the limits established by the FCC, do not pose a public health risk or cause any adverse health effects. In May 2010, the Interphone project, coordinated by the International Agency for Research on Cancer, which was the largest study of cell phone use and brain tumors ever undertaken and included substantial numbers of subjects using cell phones for ten years or longer, found that ‘overall, no increase in risk was observed with the use of mobile phones.’ “
