Elderly subjects showed a statistically significant increase in inter-hemispheric coherence of frontal and temporal alpha rhythms during GSM exposure compared to young subjects.

Plain English Summary

Summary written for general audiences

Researchers recorded eyes-closed resting EEG data from 16 healthy elderly subjects and 5 young subjects during GSM-on and GSM-off conditions lasting 45 minutes each. Spectral coherence measured inter-hemispheric synchronization across delta, theta, and alpha frequency bands. Elderly subjects showed a statistically significant increment of inter-hemispheric coherence of frontal and temporal alpha rhythms during the GSM condition compared to young subjects. The results suggest GSM-EMFs affect inter-hemispheric synchronization of alpha EEG rhythms as a function of physiological aging.

Study Details

It has been reported that GSM electromagnetic fields (GSM-EMFs) of mobile phones modulate – after a prolonged exposure – inter-hemispheric synchronization of temporal and frontal resting electroencephalographic (EEG) rhythms in normal young subjects [Vecchio et al., 2007]. Here we tested the hypothesis that this effect can vary on physiological aging as a sign of changes in the functional organization of cortical neural synchronization.

These results suggest that GSM-EMFs of a mobile phone affect inter-hemispheric synchronization of the dominant (alpha) EEG rhythms as a function of the physiological aging.

Quick Questions About This Study

Researchers recorded eyes-closed resting EEG data from 16 healthy elderly subjects and 5 young subjects during GSM-on and GSM-off conditions lasting 45 minutes each.
Elderly subjects showed a statistically significant increment of inter-hemispheric coherence of frontal and temporal alpha rhythms during the GSM condition compared to young subjects.
Spectral coherence evaluated inter-hemispheric synchronization at delta, theta, alpha 1, alpha 2, and alpha 3 bands.
The study included 16 healthy elderly subjects and 5 young subjects in the main experiment, and aging effects were investigated comparing elderly subjects to a young group of 15 subjects from a reference study.
The results suggest that GSM-EMFs of a mobile phone affect inter-hemispheric synchronization of the dominant alpha EEG rhythms as a function of physiological aging.
