Inclusion criteria

Inclusion criteria: all patients who are to undergo intracranial EEG evaluation (electrode implantation) in the UMCU, as part of the diagnostic protocol as decided by the National Dutch Taskforce on Epilepsy Surgery

Design outcomes

Primary

Measure	Time frame
Cortical area (gyral location, surface delineation) of the epileptic source. Difference (location, surface) between predicted source with EEG-fMRI and gold standard (intracranial EEG).	—

Secondary

Measure	Time frame
Successful seizure outcome after 1 year postresection.	—
