Direct electrical stimulation (DES) has long been used in patients undergoing epilepsy surgery for two key purposes: functional brain mapping and seizure triggering. In this review, the findings from DES applications to the opercula are synthesized, with the aim of mapping opercular functions and investigating seizure induction....
No actionable change for audiologists — this review concerns neurosurgical brain mapping in epilepsy and has no direct audiology or hearing-rehabilitation clinical implication.
The opercular region includes auditory cortex representations, so neurophysiologists and researchers studying central auditory processing may find this mapping data peripherally relevant, though the primary audience is epilepsy surgery teams.
- 01Reviews direct electrical stimulation of the opercula in the context of epilepsy surgery.
- 02Covers functional brain mapping and seizure triggering from opercular stimulation.
- 03Published in the Journal of Clinical Neurophysiology.
- 04Opercular cortex has some overlap with auditory and speech processing regions.
- 05No original data; review article without abstract provided.
Direct electrical stimulation of the opercula can be used for functional brain mapping and to trigger seizures during epilepsy surgery.
