" Results in sensor and source space showed a significant modulation of MEG alpha band activity after the radiofrequency exposure, with different involved cortical regions in relation to the eyes condition, probably because of different attention level with open or closed eyes." {Credits 1} " Observed results indicated a significant effect of 900 MHz RF-EMF exposure on the alpha band MEG activity detected in sensor and source space, mainly represented as a decrease of spectral power amplitudes. In particular, EO [Eyes open] resting-state sensor analysis revealed a modification of the entire alpha band and both frequency sub-bands after RF-EMF exposure, especially at the parietal cortex. These results were confirmed by analysis at source level, showing an alpha band modulation widespread at the fronto-parietal region. Otherwise, with the sensor space analysis of MEG recordings in EC [Eyes close] condition, results showed a decrease of the entire alpha band power and the upper alpha power after RF-EMF exposure, especially at the temporo-occipital region. The results were supported by source space analysis, which also highlighted the power modulation of the lower alpha band." {Credits 1} {Credits 1} 🎪 Wallace, J., Yahia-Cherif, L., Gitton, C. et al.
