a EEG of one patient with ocular phenotype solely: during sleep there were sporadic or continuous low amplitude SWC discharges in region of right central, medial and posterior temporal lobe, medial temporal more pronounced. b EEG with oculomotor apraxia and newly onset epilepsy: sporadic or continuous low-amplitude SWC, polyspike and wave complex discharges were seen in the region of bilateral parietal, occipital, posterior temporal lobe. c EEG of transitional patient (Patient 12) who reported initial seizure: there was a burst of polyspike and wave complex, spikes in bilateral central, parietal regions, spreading to other leads. Note: an average referential montage was applied, the electrodes of EEG documents from top to bottom are marked as follows: Fp1 (left frontal pole), Fp2 (right frontal pole), F3 (left frontal), F4 (right frontal), C3 (left central), C4 (right central), P3 (left parietal), P4 (right parietal), O1 (left occipital), O2 (right occipital), F7 (left anterior temporal), F8 (right anterior temporal), T3 (left mid-temporal), T4 (right mid-temporal), T5 (left posterior temporal), T6 (right posterior temporal)
