ECoG
Pronunciation: EE-kog
Also written as: ECoG — Electrocorticography
Electrocorticography; direct brain surface electrical recording using implanted electrodes.
Full Definition
ECoG (electrocorticography) is the abbreviated term for direct electrical recording from the brain surface using surgically implanted electrode grids or strips. This invasive monitoring technique offers superior signal quality and spatial resolution compared to scalp EEG, making it invaluable for precise seizure localization and functional brain mapping during presurgical evaluation. ECoG recordings are typically performed in specialized epilepsy centers as part of comprehensive presurgical workup.
Usage
Usage note: Distinguish from ECG (electrocardiogram) and EOG (electrooculogram) by context.
