Human resting-state EEG and radiofrequency GSM mobile phone exposure: The impact of the individual alpha frequency
Abstract
Overview
The investigation focuses on the effects of GSM mobile phone exposure on brain activity, particularly through the lens of resting-state EEG impacts, emphasizing Alfa band modulation.
Purpose
- The primary aim of the study is to examine the radiofrequency electromagnetic fields (RF-EMF) and their influence on alpha band power spectral density (PSD) during EEG analysis, partly to account for variability between individual physiological brain states.
Materials & Methods
- 21 healthy volunteers participated in a study using a double-blind, randomized, and counterbalanced crossover design.
- The subjects were exposed to a real or sham GSM mobile phone emitting at 900 MHz, analyzing differences in alpha band frequencies during EEG in both eyes-open and eyes-closed conditions.
Findings
- Experiments showed changes in the alpha band EEG power during exposure but were not statistically significant and did not establish a clear sensitivity to RF-EMF based on individual alpha frequency variability.
Conclusion
The conclusion highlights the absence of significant alpha band activity modulation due to RF-EMF in a resting state and suggests a potential delay post-exposure might reveal more about EEG spectral power modulations.
