Effect of exposure to 900 MHz radiofrequency on the MEG alpha band activity at rest

With the extensive use of mobile phones several studies have been realized to understand the effects of radiofrequency exposure on brain activity. Results show changes in the alpha band spectral power. To better understand the cortical structures involved in these changes after exposure at 900 MHz, we carried out electroencephalography and magnetoencephalography recordings followed by the anatomical magnetic resonance imaging. Healthy volunteers were selected according to strict inclusion criteria. Preliminary results on MEG sensor space showed a modification of the alpha band right after exposure. Data analyses of MEG recordings on sensor space and source space are still under process and ready results will be presented at the conference
