High-density ECoG improves the detection of high frequency oscillations that predict seizure outcome

E Boran, G Ramantani, N Krayenbühl… - Clinical …, 2019 - Elsevier

Residual fast ripples in the intraoperative corticogram predict epilepsy surgery outcome

MA van't Klooster, NEC Van Klink, FSS Leijten… - Neurology, 2015 - AAN Enterprises
Objective: We studied whether residual high-frequency oscillations (80–500 Hz; ripples, 80–
