Cortical electrode

Cortical electrodes are sterile, invasive medical devices designed to be temporarily placed on the brain’s surface for precise recording of electrical activity or targeted stimulation. They provide detailed insights into brain function, aiding in epilepsy diagnosis, presurgical mapping, or research into neurological disorders by offering localized data that scalp electrodes cannot match.

These devices are typically regulated as single-use medical instruments, requiring sterile handling and adherence to invasive device standards. They are often supplied as part of a system that includes recording or stimulation equipment, with classification and supply rules varying by jurisdiction. Always check local regulations before use or procurement.
