Effects of mobile phone electromagnetic fields on brain waves in healthy volunteers

Abstract

Overview

The study investigates the interaction between electromagnetic fields (EMF) and biological tissue, focusing on EEG responses in healthy volunteers. Rising interest in this area is spurred by the increasing prevalence of EMF exposure.

Methodology

• Utilization of a double-blinded, crossover counterbalanced design involving 32 participants.
• Participants were divided into two groups, each undergoing two 18-minute sessions with alternating exposure conditions.
• EEG recordings captured from 63 electrodes across 6 brain regions during sessions with eyes open and closed.
• A Bayesian statistical approach was taken to analyze the data.

Findings

Statistical evidence indicated a significant effect of EMF on alpha band power density during the eyes open condition. The study design and analytical methods helped mitigate common confounds seen in previous research.

Conclusion

Results suggest a measurable impact of EMF on brain wave patterns, specifically in the alpha band during exposure, dismissing the likelihood of these effects being artefacts. The established protocol is also suggested for future research on newer transmission technologies and more detailed dose-effect relationships.
