Effects of Mobile Electromagnetic Exposure on Brain Oscillations and Cortical Excitability: Scoping Review

AI: Melanie Research RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This scoping review evaluates evidence on mobile phone electromagnetic exposure and its effects on brain oscillations and cortical excitability in healthy individuals. Across 78 EEG studies (and 2 TMS studies), the authors report that exposure may be linked to changes in neural activity, including increased amplitudes in several EEG bands and possible changes in cortical silent period. However, substantial methodological inconsistency across studies limits firm conclusions, and the review highlights limited evidence for 5G/mmWave exposures and argues for precaution and potential guideline revision.

Key points

The review focuses on mobile phone electromagnetic exposure and neurophysiological outcomes measured by EEG and TMS.
Seventy-eight included studies used EEG, while only two studies used TMS as a primary tool.
Reported findings suggest mobile EM exposure may increase amplitudes in alpha, beta, theta, and delta EEG bands, especially with eyes closed.
The review reports possible enhancement of cortical silent period, interpreted as altered excitatory/inhibitory mechanisms.
The authors emphasize major inconsistencies in experimental methods that limit definitive conclusions.
Evidence on 5G, particularly mmWave (>24 GHz), is described as limited and needing urgent research.
The authors call for improved study quality, standardized exposure parameters, and consideration of age and gender in future designs.
The review argues that observed neurophysiological changes support reconsideration of safety guidelines such as SAR limits.
