Description
Summary:•Wide-spectrum, intrinsic brain activities allow for non-stimulus functional brain mapping.•Multi-component mapping yielded significantly higher accuracy than single-component mapping.•Multi-component ECoG-based mapping may be a feasible alternative to cortical stimulation mapping. To assess the feasibility of multi-component electrocorticography (ECoG)-based mapping using “wide-spectrum, intrinsic-brain activities” for identifying the primary sensori-motor area (S1-M1). We evaluated 14 epilepsy patients with 1514 subdural electrodes implantation covering the perirolandic cortices at Kyoto University Hospital between 2011 and 2016. We performed multi-component, ECoG-based mapping (band-pass filter, 0.016–300/600 Hz) involving combined analyses of the single components: movement-related cortical potential (
