Plain English Summary
Researchers exposed rabbits to cell phone radiation (800 MHz) positioned near their heads, similar to how humans use phones, and measured brain electrical activity using EEG recordings. They found that 9 out of 10 animals showed significant changes in brain wave patterns within 100 milliseconds of exposure, with increased randomness in brain activity that lasted about 300 milliseconds. This demonstrates that cell phone radiation can directly alter brain function when absorbed by brain tissue.
Why This Matters
This study provides compelling evidence that cell phone radiation produces measurable, immediate changes in brain electrical activity. What makes this research particularly significant is the rigorous experimental design - the researchers ruled out equipment interference by testing dead animals (no effect) and showed the effect was location-specific by moving the antenna away from the head (no effect). The 600 mW power level used falls within the range of typical cell phone emissions during calls. The fact that brain changes occurred within 100 milliseconds of exposure suggests a direct biological response rather than a heating effect. While this was an animal study, the implications for human brain function during phone calls are clear and concerning, especially given that billions of people hold these devices against their heads daily.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 800 MHz band cellular telephone
Study Details
We studied the effect of an electromagnetic field from a cellular telephone on brain electrical activity, using a novel analytical method based on a nonlinear model.

When the rabbits were exposed to the radiation from a standard cellular telephone (800 MHz band, 600...
We conclude that, in normal use, the fields from a standard cellular telephone can alter brain function as a consequence of absorption of energy by the brain.
