Z-statistics and x, y, and z MNI coordinates (mm) are from the location of peak voxel within each cluster (or local maxima within clusters, indicated by indented regions). Z-statistic maps were whole-brain cluster-corrected at Z > 1.96, p < 0.05. No regions showed significant clusters for positive correlation with SSRT.
