Figure 2 Interictal scalp EEG: left temporal spikes (circled), FBG (left frontobasal electrode), FBD (right frontobasal electrode), TBG (left temporobasal electrode), TBD (right temporobasal electrode).

Figure 3 Interictal scalp EEG: bilateral sharp waves.

Figure 4 Ictal scalp EEG: A) Seizure-onset, tachycardia, depression of EEG activity as regards TP8, T4. B) Bilateral depression of EEG activity, rhythmic theta activity on the right hemisphere. C) Bilateral rhythmic theta activity predominating over the right hemisphere and the temporal regions. D) Seizure ending on the right hemisphere. E) Seizure ending on the left hemisphere.
