Seizures induced by cortical stimulation are as effective as spontaneously induced seizures in identifying the epileptogenic zone.
Why this matters
In patients with epilepsy, cortical stimulation is used in association with intracranial electroencephalography (EEG) to define the epileptic generator zone and for functional mapping.
There have been very few studies evaluating the association between cortical stimulation and surgical outcomes.
Identifying the epileptogenic zone and therefore the seizure-onset zone (SOZ) through cortical stimulation may shorten the length of time needed for presurgical evaluation and is associated with positive postsurgical outcomes.
