Surface Electrode for Electroencephalography
The Electrode Store
FDA Clearance Information
The surface electrode for EEG was cleared by the FDA via the 510(k) pathway on August 13, 2002. It is manufactured by The Electrode Store and classified as a Class 2 device.
What It Is
FDA-Cleared Indications
- Recording electrical activity from the brain through scalp electrodes during an electroencephalogram (EEG).
Clinical Applications
- Routine or prolonged EEG recording in clinical settings
- Monitoring brain-wave activity during neurological evaluation
- Use as part of EEG-based assessment when directed by a qualified clinician
Reported off-label uses
- Research recording of high-frequency EEG oscillations as potential biomarkers in epilepsy
- Research and clinical monitoring applications involving quantitative EEG analysis
Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations
- The electrode must be applied to the scalp with appropriate conductive material and securely connected to compatible EEG recording equipment.
- Skin preparation may be needed to reduce impedance and improve signal quality; the skin should be checked for irritation after removal.
- This is an external recording electrode and does not penetrate the skull or brain.
- MRI compatibility depends on the specific electrode construction, lead wires, and connected EEG system; verify labeling before MRI exposure.
- Avoid use on damaged or infected scalp skin unless specifically directed by a clinician.
