Visualization of ECoG electrodes mapped to MNI152 space for the B(RAIN)2 Dataset 1. (a) Schematic representation of the ANTs non-linear transformation workflow, mapping subject-specific electrode locations from native RAS space to MNI152 space. (b–d) Group-level visualization of ECoG electrodes across the cortical surface in MNI152 space, reflecting the overall distribution and coverage from the dataset. Electrode coordinates for all subjects in both native and MNI spaces are available in the shared database.
