a Abnormal EEG record during sham exposure to mobile phone radiation (MPR) of patient G7. There is paroxysm of generalized, bilateral, synchronous spike-slow, and sharp-slow wave complexes, the background activity. A referential montage was used and gain set at 10 uV. b1, b2 Abnormal EEG record during real exposure to MPR for the same patient (G7). A referential montage gain was set on 20 μv. There are spontaneous bursts of recruiting building up pattern of generalized bisynchronous, symmetrical polyspikes that are discharging “fast”; at a rate of 6 and 10 Hz with extremely short periods of near-normal background activity that lasted for more than 30 s (B1), followed by high-voltage, irregular 2- to 5-Hz slow waves with intermixed spikes (B2). c EEG record 5 min after termination of the phone call of the same patient (G7). It shows normalization of the background activity (8–9 Hz alpha waves). Gain set at 10 uV
