View Original AbstractEvoked potentials were found in 90% of volunteers exposed to mobile-phone-type pulses, detected using a nonlinear EEG analysis method.
Plain English Summary
Researchers recorded EEGs from six standard locations in 20 volunteers to detect brain potentials triggered by a pulse of the type produced by mobile phones. Evoked potentials having the expected latency were found in 90% of the volunteers, as assessed using a nonlinear method of EEG analysis. Evoked potentials were not detected when the EEG was analyzed using time averaging. The possibility of systematic error was excluded by sham-exposure analyses.
Why This Matters
The researchers hypothesized that low-frequency pulses produced by mobile phones at 217 Hz were detected by sensory transduction, as evidenced by the ability of the pulses to trigger evoked potentials. The results implied that mobile phones trigger evoked potentials at the rate of 217 Hz during ordinary phone use. The researchers noted that chronic production of the changes in brain activity might be pertinent to reports of health hazards among mobile-phone users.

Exposure Context
This study used 100 V/m for electric fields:
- 333.3x above the Building Biology guideline of 0.3 V/m
This study used 0.003 mT for magnetic fields:
- 150x above the Building Biology guideline of 0.2 mG
- 30x above the BioInitiative Report recommendation of 1 mG
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
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).
