a Normal EEG record in an epileptic patient during sham exposure to mobile phone radiation (MPR) shows normal background activity at 9–10 Hz alpha waves, using a referential montage with gain set on 10 uV. b Abnormal EEG record during real exposure to MPR of the same previous patient shows left anterior temporal (T3/T5) sharp-slow wave complexes, using a referential montage with gain set at 15 uV. The background activity became slightly slowed at 7–8 Hz
