TABLE 3.
Electrode locations on the scalp labelled using AtlasLabel in FSL and the Harvard‐Oxford Cortical Structural atlas. For each electrode we calculated the percentage of participants reporting each anatomical label as the highest probability region. The closest Brodmann area for the mean MNI coordinate at each electrode projection is also detailed (generated with BioImage Suite)
