Epileptogenic networks in nodular heterotopia: A stereoelectroencephalography study

Summary 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; EI ) and interictal recordings...
