Figure 1

Preoperative interictal EEG discharges over the right temporal region during sleep in longitudinal bipolar (A) and referential (B) montages.

Figure 2

Preoperative ictal EEG onset in the right temporal lobe (A) and postoperative ictal EEG onset mainly over the left temporal lobe although an early but much less prominent involvement of the right temporal lobe can be noticed 180 seconds after the beginning of seizure-eliciting music (B). Red arrows indicate occurrence of aura and yellow arrows point to ictal EEG activity. EEG format: 30 seconds/per page.
