Mapping intraoperative interictal epileptiform discharges using high-resolution, thin-film cortical arrays.

Key Points

• The study aims to examine the effectiveness of μECoG arrays in mapping IEDs compared to traditional methods.
• Utilized μECoG arrays for intraoperative monitoring.
• Analyzed microscale spatiotemporal activity of interictal epileptiform discharges (IEDs).
• Compared data from high-resolution arrays to standard macroscale devices.
• μECoG arrays successfully tracked spatiotemporal patterns of IEDs.
• Standard macroscale devices inadequately captured specific IED patterns.
• Support for μECoG arrays in presurgical planning was demonstrated.
