A possible variant of negative motor seizure arising from the supplementary negative motor area

Highlights • The patient's semiology suggested a variant of negative motor seizure. • Seizure freedom was achieved by resection of the tumor and the adjacent supplementary negative motor area (NMA) with frequent spikes in acute ECoG. • The symptomatogenic zone and probably the ictal onset zone...

Zusammenfassung:	Highlights • The patient's semiology suggested a variant of negative motor seizure. • Seizure freedom was achieved by resection of the tumor and the adjacent supplementary negative motor area (NMA) with frequent spikes in acute ECoG. • The symptomatogenic zone and probably the ictal onset zone were located at the supplementary NMA.
