GSM stimulation modulated interhemispheric frontal and temporal coherence at alpha2 and alpha3 bands compared to sham stimulation.

Plain English Summary

Summary written for general audiences

Ten subjects underwent two EEG recordings separated by one week in a crossover double-blind paradigm. The mobile phone was held on the left side of the head by a modified helmet. Each session lasted 45 minutes with real GSM exposure in one session and sham in the other. GSM stimulation modulated interhemispheric frontal and temporal coherence at alpha2 and alpha3 bands compared to sham.

Why This Matters

The researchers hypothesized that electromagnetic fields from mobile phones affect interhemispheric synchronization of cerebral rhythms. Functional interhemispheric connectivity was modeled using EEG spectral coherence between frontal, central, and parietal electrode pairs, examining delta, theta, and alpha sub-bands. The authors suggest that prolonged mobile phone emission affects cortical activity and the spread of neural synchronization through interhemispheric functional coupling of EEG rhythms.

Study Details

We tested the working hypothesis that electromagnetic fields from mobile phones (EMFs) affect interhemispheric synchronization of cerebral rhythms, an important physiological feature of information transfer into the brain.

The present results suggest that prolonged mobile phone emission affects not only the cortical activity but also the spread of neural synchronization conveyed by interhemispherical functional coupling of EEG rhythms.
