  • BA, Brodman area; k, cluster extent (number of voxels); x/y/z, coordinates of peak voxel in significant clusters (Talairach space); if clusters extend into both hemispheres, this is indicated by left/right (if peak voxel is located in the left hemisphere) or right/left (if peak voxel is located in the right hemisphere).
