Note in EEG (a) fragmented generalized spike-and-wave and EEG (b) generalized 3 Hz mainly slow-wave discharges during sleep, with no concomitant clinical events recorded. Ictal-EEG (c) shows hyperventilation. During the evoked generalized spike-and-slow wave discharge, eyes opened with the head slightly turning back (first arrow) and after about half a second closed again (second arrow).
