Theta brainwaves were significantly modulated during exposure to RF-EMF related to MPs, and this modulation depended on eye condition (closed or open).

Plain English Summary

Summary written for general audiences

Twenty-one healthy volunteers were exposed to a GSM signal at 900 MHz with specific absorption rates of 0.49 W/kg (10 g tissue) and 0.70 W/kg (1 g tissue). Delta and beta rhythms of resting EEG were not affected by the exposure. Theta brainwaves were significantly modulated during exposure, and this modulation depended on whether eyes were closed or open.

Why This Matters

The study strongly suggests that acute exposure to RF-EMF alters the EEG theta rhythm at rest. They noted that long-term exposure studies are required to explore the effect of this disruption in high-risk or sensitive populations.
