 <p>Brain activity was recorded with a combination of intracranially subdural platinum-iridium electrodes embedded in SILASTIC sheets (2.3 mm diameter contacts, Ad-Tech Medical Instrument and PMT Corporation) and/or depth stereo-electroencephalographic platinum- iridium electrodes (PMT Corporation; 0.8-mm diameter, 2.0-mm length cylinders; separated from adjacent contacts by 1.5 to 2.43 mm), or Behnke-Fried depth stereo- electroencephalographic platinum-iridium electrodes (Ad-Tech Medical, BF08R-SP21X-0C2, 1.28 mm in diameter, 1.57 mm in length, 3 to 5.5 mm spacing). The decision to implant, electrode targeting, and the duration of invasive monitoring was solely determined on clinical grounds and without reference to this or any other study. Electrodes were arranged as grid arrays (either 8 × 8 with 10 mm center-to-center spacing, 8 x 16 contacts with 3 mm spacing, or hybrid macro/micro 8 x 8 contacts with 10 mm spacing and 64 integrated microcontacts with 5 mm spacing), linear strips (1 × 8/12 contacts), depth electrodes (1 × 8/12 contacts), or a combination thereof. Subdural electrodes covered extensive portions of lateral and medial frontal, parietal, occipital, and temporal cortex of the left and/or right hemisphere. Recordings from grid, strip and depth electrode arrays were done using a Natus Quantum amplifier (Pleasonton, CA) or a Neuralynx Atlas amplifier (Bozeman, MT). A total of 4057 electrodes (892 grids, 346 strips, 2819 depths) were implanted across 32 patients with drug-resistant focal epilepsy undergoing clinically motivated invasive monitoring. 3512 electrodes (780 grids, 307 strips, 2425 depths) that were unaffected by epileptic activity, artifacts, or electrical noise were used in subsequent analyses. To determine the electrode localization for each patient, a postoperative CT (computed tomography) scan and a pre-operative T1 MRI were acquired and co-registered. Recordings were obtained continuously during the patients’ stay in the hospital. All data was stored with stimulus and timing markers permitting offline synchronization.</p>

-<p>Before the participants underwent surgery and electrode implantation, T1-weighted MR data were acquired from them. At NYU, imaging was performed using the Siemens Biograph mMR scanner. At Harvard, the imaging sequence utilized was MPRAGE (magnetization-prepared rapid gradient-echo), with a Siemens Skyra 3T scanner. At WU, imaging was conducted using the GE MEDICAL SYSTEMS SIGNA Artist scanner. The rationale behind acquiring MR scans was the spatial resolution it offers for brain tissue visualization.</p>
