x, y, z are MNI coordinates of minimum and maximum values. Negative x values, left side of the brain; positive x values, right side of the brain. Brodmann's area (BA) and anatomic region (Region) derived from the Talairach Daemon [Lancaster et al., 2000] after converting MNI to Talairach coordinates. BA and region denote the closest gray matter voxel to that location.
