Representative EEG tracings. a EEG data from subject 11 demonstrating generalized irregular spike-and-wave discharges at ~ 5 Hz associated with eye blink (arrow) and b without eye blink. c EEG data from subject 8 displays photosensitive generalized and irregular spike-and-wave discharges. Double-headed, horizontal arrow and vertical lines denote duration of 15 Hz photic stimulation. Normal background EEG activity is observed in both subjects. EEG, electroencephalogram
