ECoGGrids
ECoG grids, or electrocorticography grids, are arrays of electrode contacts placed directly on the surface of the cerebral cortex to record electrical activity. They are a form of invasive neural interface used primarily in clinical and research settings to monitor brain function and to localize epileptogenic tissue, as well as to study cortical processing and develop brain-computer interfaces.
Construction and configuration: ECoG grids are typically constructed on a flexible, biocompatible substrate such as silicone
Applications: Clinically, ECoG grids are employed during pre-surgical monitoring for epilepsy to localize seizure foci and
Procedure and limitations: Placement requires a craniotomy and placement on the exposed cortex, usually for short-term
Signal characteristics: Recorded activity comprises local field potentials with sensitivity to clinically relevant bands, including high
