Mapping Epileptic Networks Using Simultaneous Intracranial EEG-fMRI

Frontiers in Neurology, 2021
Background: Potentially curative epilepsy surgery can be offered if a single, discrete epileptogenic zone (EZ) can be identified. For individuals in whom there is no clear concordance between clinical localization, scalp EEG, and imaging data ...
