Notes: Regions were automatically reported and labeled using bspmview (http://www.bobspunt.com/software/bspmview) and AnatomyToolbox atlas (http://www.fz-juelich.de/inm/inm-1/EN/Forschung/_docs/SPMAnatomyToolbox/SPMAnatomyToolbox_node.html). x, y, and z=MNI coordinates in the left–right, anterior–posterior, and inferior–superior dimensions, respectively.

^aPositive and negative effects at a given threshold (cluster p<0.05, GRF corrected) are shown.
