Cluster statistics
voxel statistics (see Methods section).
Areas in boldface within sections indicate changes in PET and LORETA in corresponding brain areas of similar size, either in uniform or opposite direction. Note that Talairach coordinates cannot be given for LORETA results based on cluster statistics.
