case_images: His EEG at 3.5 and 6.5 years after the first and second events, respectively, revealed normal background activity during wakefulness and repetitive high voltage tangential dipoles with frontal/central positivity and the main negative peak bi-occipitally maximal in the left occipital area, showing marked drowsiness and sleep activation (Figures 1 and 2).
