Plain English Summary
Researchers tested whether cell phone signals can trigger measurable brain responses by exposing 20 volunteers to the low-frequency pulse pattern (217 Hz) that cell phones emit. They found that 90% of participants showed detectable brain activity changes (called evoked potentials) in response to these pulses, suggesting the brain can sense and respond to cell phone signals even when people aren't consciously aware of it.
Why This Matters
This study provides compelling evidence that our brains are not passive recipients of cell phone radiation - they actively detect and respond to the signals our devices emit. The 217 Hz pulse rate studied here is the same frequency pattern your phone produces during normal calls, meaning your brain may be experiencing these measurable changes in electrical activity every time you use your device. What makes this research particularly significant is that it demonstrates a clear biological mechanism through which cell phones could potentially affect brain function. The researchers used rigorous controls including sham exposures to rule out experimental errors, and the 90% response rate suggests this is a consistent biological phenomenon, not a random occurrence. The science demonstrates that even if you don't feel anything when using your phone, your brain is registering the exposure at a neurological level.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 217 Hz
Study Details
We hypothesized that the low-frequency pulses produced by mobile phones (217 Hz) were detected by sensory transduction, as evidenced by the ability of the pulses to trigger evoked potentials (EPs).
Electroencephalograms (EEGs) were recorded from six standard locations in 20 volunteers and analyzed...
Evoked potentials having the expected latency were found in 90% of the volunteers, as assessed using...
The results implied that mobile-phones trigger EP at the rate of 217 Hz during ordinary phone use. Chronic production of the changes in brain activity might be pertinent to the reports of health hazards among mobile-phone users.
