Preresection intraoperative electrocorticography (<scp>EC</scp>oG) abnormalities predict seizure‐onset zone and outcome in pediatric epilepsy surgery

Abstract

Electrographic seizures and frequent spikes are frequently seen on pre-resection ECoG in children. The brain locations corresponding to these discharges are highly concordant with the seizure-onset zone; resection of these regions is correlated with good seizure outcome. Further research is needed to design interventions that increase the reliability of ECoG prediction of the epileptogenic zone and obviate the need for IEM.
