The magnitude of the cluster, calculated as the standard deviation (SD) of the lengths from the individual equivalent current dipoles to the cluster centroid, indicates the approximate radius of a sphere for locations within 1 standard deviation of the centroid. The scale of the coordinates is in millimeters and the coordinates are given in Talairach coordinates (Talairach & Tournoux, 1988).
