Description: We have simulated several scenarios where intracranial EEG electrodes are implanted in an average brain. Files contain the position of electrodes over the cortex (ECoG grids) or inside the brain tissue (SEEG depth electrodes). Several locations over the cortex (57), rotations, array sizes (from 8 to 256 electrodes), and inter-electrode distances (3, 5, and 10 mm) have been simulated. Approximately 3300 grid and 850 depth implantation scenarios were simulated. Additionally, more than 50000CT artefacts produced by these electrodes were also simulated, using 12 different noise levels. We also simulated overlapping grids.
