Surgical management of cortical lesions adjacent to or within the eloquent cerebral cortex requires a critical risk: benefit analysis of the procedure before intervention. This study introduced a measure of surgical risk, based on preoperative magnetoencephalographic (MEG) sensory and motor mapping, and tested its value in predicting surgical morbidity. ⋯ Our results suggest that MEG mapping-derived FRPs can serve as powerful tools for use in presurgical planning and during surgery.
