Intraoperative electrocorticography in awake brain surgery: comparing three electrode configurations for detecting stimulus-induced and spontaneous epileptiform activity
This study demonstrates a higher rate of detection of epileptiform activity with circular and standard grids when compared with strip electrodes. The standard HD grid was used less during electrical stimulation, demonstrating the importance of both the number of contacts and design array when considering optimal conditions for ECoG and functional brain mapping.
