Human EEG and microwave radiation from cell phones

The effects of exposure to microwave radiation from cellular mobile telephones on human brain wave potentials or electroencephalograms have been studied. In particular, a large number of small, metallic electrodes typically are placed upon a subject´s scalp, with electrically conducting paste or a glue-like substance to hold them in place. Low voltage signals (< 500 μV) are amplified by the electronics in the EEG recording system. The resulting polygraphic display is then read by unaided visual inspection, followed by spectral analysis.
