Figure 1.
- The interictal EEG a) reveals an abnormal asymmetric slow spike-wave activity of 1.5 to 2 Hz and wave discharges associated with electrodecrement in the left hemisphere, consistent with findings of asymmetric Lennox–Gastaut syndrome. Settings: sensitivity, 7 μV/mm; high-frequency filter, 70 Hz. b) shows many spikes in multiple left-brain areas (T3, F7, T5, C3, and P3). Settings: sensitivity, 7 μV/mm; high-frequency filter, 70 Hz.
