Cortical electrode

Definition

A sterile, invasive, electrical conductor that is temporarily placed (< 30 days) on the surface of the brain to stimulate the brain or to record the brain's electrical activity (with more precise localization than a scalp electrode). It is typically a series of discs mounted in thin plastic strips, or in a square/rectangular grid to cover larger surface areas. The implanted device, also known as a subdural electrode, is connected to recording, monitoring, or stimulation/response devices [e.g., electroencephalograph (EEG), evoked-potential recorder, stimulator]. This is a single-use device.
