^aFrequent interictal spikes were noted in the right inferior frontal‐parietal regions.

^bOccasional generalized spike‐wave discharges were noted; lesionectomy of the tumor in the left temporal region was performed.

^cHabitual seizures failed to be captured during chronic ECoG recording; no resective surgery was performed. However, habitual seizures characterized by forced head‐deviation toward the left side were captured during preoperative scalp EEG recording; thereby, delayed ictal discharges were noted over the right hemisphere but further localization of the presumed epileptogenic zone was not tenable in Patient 9.
