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.
Abbreviations: ACC, anterior cingulate cortex; ALFF, amplitude of low-frequency fluctuation; CTN, classic trigeminal neuralgia; GRF, Gaussian random field; HC, healthy control; L, left; MNI, Montreal Neurological Institute; R, right.
