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…

This feasibility study tested whether microwave radiation (450 MHz, 40 Hz modulation; 1 g peak spatial average SAR 0.3 W/kg) can induce detectable event-related potentials in EEG. In one subject across four sessions, EEG responses time-locked to exposure offset showed increased alpha-band signal and about a twofold…

This study evaluated whether exposure to EMF from an LTE system (described as equivalent to maximum LTE mobile phone emission) alters resting-state EEG. The abstract reports reduced spectral power and reduced interhemispheric coherence in alpha and beta bands in frontal and temporal regions. It also reports no…

This volunteer study examined short-term non-thermal RF EMF exposure and reported changes in EEG spectra. The main reported effect was amplification of alpha-range energy, with the magnitude depending on baseline EEG typological features. The abstract also reports that combining RF EMF exposure with monotonous…

This double-blind, counterbalanced cross-over study investigated whether extremely low frequency (DC to at least 40 kHz) fields emitted by GSM handsets affect resting EEG. In 72 healthy volunteers, the authors report a decrease in the alpha band during 20 minutes of ELF exposure in the exposed hemisphere only. They…
