case_images: Ictal EEG revealed very discrete abnormalities in all seizures visible 1 to 3 s before the clinical onset and characterized by a generalized flattening, sometimes predominating in the midline frontocentral electrodes (Fz, Cz) followed by a focal theta (4 c/s) rhythmic activity lasting several seconds in the same electrodes (Figs. 1A and B). Interictal spikes were rarely observed in the left and midline frontal electrodes (F3, Fz) (Fig. 1C).
