Brain Regions with significant (p < 0.005) positive relationships between waist circumference (cm) and brain activation as measured with [¹⁵O]H₂O positron emission tomography following mental stress (mental arithmetic, public speaking). The XYZ coordinates identify the cluster peak with sub-cluster peaks occurring > 8mm away also presented. Voxel number refers to number of voxels in cluster with Z-score of cluster/sub-cluster peak also presented.
