a Abnormal EEG record during sham exposure to MPR of patient G4, showing generalized, bilateral, synchronous spike-slow wave complex, and sharp wave, using a referential montage with gain set at 15 uV. The background activity was 8 Hz. b Abnormal EEG record during real exposure to MPR of the same patient (G4). There is a recurrent paroxysm of generalized, bilateral, synchronous polyspike-slow, and sharp-slow wave complexes during which the background activity showed a drop of both frequency and amplitude. A referential montage was used with gain set at 50 uV. c Abnormal EEG record at the after-exposure period to MPR of the same patient (G4) showing a brief paroxysm of generalized, bilateral, and synchronous spike-slow wave complexes like that recorded during the sham exposure. A referential montage was used with gain set at 10 uV. The background activity resumed its original frequency and amplitude
