Figure 1 EEG recording showing abnormal pattern during wakefulness with runs of 2-3-Hz high amplitude and synchronous slow waves predominant over posterior regions associated with few spikes and slow-wave spikes over temporal regions. Low filter: 0.53 Hz; high filter: 60 Hz.



Figure 2 EEG recording during wakefulness showing high-amplitude generalised delta waves with a certain degree of interhemispheric synchronisation and associated multifocal paroxysmal discharges. Low filter: 0.53 Hz; high filter: 60 Hz.
