Aim of study (according to author)
This in vivo study was performed to investigate whether GSM signals affect the electrical activity of the human brain.
Nine healthy subjects and six epileptic patients participated. Each participant was exposed and sham-exposed.
- effects on the neurological system: brain activity
General category: mobile communication system, digital mobile phone, GSM
| 900 MHz |
exposure duration: continuous for 250 s?
FIELD View further expo parameters
Methodsinvestigation on living organism
investigated organ system: brain/CNS
Main outcome of study (according to author)
Under radiofrequency irradiation the spectral arrangement of the EEG activity was altered for healthy subjects as well as epileptic patients. For the healthy subjects, a significant decrease of the EEG signal was observed for all frequency bands and more precisely on occipital electrodes for the alpha wave. For the epileptic patients, it was the opposite since the GSM exposure produced an increase of EEG signal energy in all frequency bands and without any local difference.
These results suggest that GSM mobile phones may have a biological effect on EEG signals.
