Objective
We studied the rate dynamics of interictal events occurring over fast‐ultradian time scales, as commonly examined in clinics to guide surgical planning in epilepsy.
Methods
Stereo‐electroencephalography (SEEG) traces of 35 patients with good surgical outcome (Engel I) were analyzed. For this we developed a general data mining method aimed at clustering the plethora of transient waveform...
Objective
Stereoelectroencephalography‐guided radiofrequency thermocoagulation (SEEG‐guided RF‐TC) aims to reduce seizure frequency by modifying epileptogenic networks through local thermocoagulative lesions. Although RF‐TC is hypothesized to functionally modify brain networks, reports of changes in functional connectivity (FC) following the procedure are missing. We evaluated, by means of SEEG recordings,...
Objective
Stereo‐electroencephalography (SEEG)‐guided radiofrequency thermocoagulation (RF‐TC) aims at modifying epileptogenic networks to reduce seizure frequency. High‐frequency oscillations (HFOs), spikes, and cross‐rate are quantifiable epileptogenic biomarkers. In this study, we sought to evaluate, using SEEG signals recorded before and after thermocoagulation, whether a variation in these markers...
Objective
Defining the roles of heterotopic and normotopic cortex in the epileptogenic networks in patients with nodular heterotopia is challenging. To elucidate this issue, we compared heterotopic and normotopic cortex using quantitative signal analysis on stereoelectroencephalography (SEEG) recordings.
Methods
Clinically relevant biomarkers of epileptogenicity during ictal (epileptogenicity index;...
