Caption: Statistical parametric map threshold set at Z>2.33 voxel, p<.05 cluster-correction; R=Right, L=Left brain hemisphere, MNI coordinates are for statistical peaks in cluster and Z Score is for corresponding coordinate location; Voxels refer to the number of standard space voxels in the cluster; p-value is the p-value significance for the cluster.
