All analyses completed using cluster thresholding (z > 2.3 and corrected cluster threshold of p < 0.05) at individual and group levels.
Z-MAX is the local maximum z value.
Voxel is the number of activated voxel within each cluster.
MNI (x, y, z) are the MNI coordinates for the local maximum.
Anatomy is the Harvard-Oxford Cortical and Subcortical Structural Atlases for the local maximum (or closet label to maximum).
