View Original AbstractUsing realistic phone-like RF exposure levels, researchers found no brain wave changes, unlike previous studies using artificially high exposures.
Plain English Summary
Researchers exposed 12 people to mobile phone-like radiofrequency radiation for 15 minutes and measured their brain waves (EEG patterns) to see if the exposure affected brain activity. They found no changes in brain wave patterns from either pulsed or continuous RF exposure. This study failed to replicate earlier research that had found brain wave changes, possibly because this study used more realistic exposure levels that better match actual phone use.
Study Details
It is not clear yet whether Global System for Mobiles (GSM) mobile phone radiation has the ability to interfere with normal resting brain function. There have been reports that GSM exposure increases alpha band power, and does so only when the signal is modulated at low frequencies (Huber, R., Treyer, V., Borbely, A. A., Schuderer, J., Gottselig, J. M., Landolt, H.P., Werth, E., Berthold,T., Kuster, N., Buck, A and Achermann, P. Electromagnetic fields, such as those from mobile phones, alter regional cerebral blood flow and sleep and waking EEG. J Sleep Res 11, 289-295, 2002.) However, as that research employed exposure distributions that are not typical of normal GSM handset usage (deep brain areas were overexposed), it remains to be determined whether a similar result patterning would arise from a more representative exposure.
In this fully counterbalanced cross-over design, we recruited 12 participants and tried to replicate...
No changes to alpha power were found for either modulated or unmodulated radiofrequency fields, and ...
