High-resolution cortical mapping within and across the central sulcus using 1024-electrode micro-electrocorticography arrays: illustrative case.

The authors demonstrate the feasibility and utility of µECoG for sensorimotor mapping within the central sulcus, revealing a phase reversal at a resolution of approximately 400 microns. Compared to standard mapping, which records gyral surface electrophysiology, they further demonstrate phase-reversal electrophysiology within a dissected central sulcus. High-resolution cortical mapping from µECoG may foster several neurosurgical advancements, from tumor resection to brain-computer interfaces. https://thejns.org/doi/10.3171/CASE25534.
