(a) Locations of the basal ganglia seeds used in the infraslow oscillation (ISO) and resting functional connectivity analysis. The seed regions are located contralateral to the CRPS affected limb. (b) The mask of the frontal lobe, anterior cingulate cortex, middle temporal gyrus, and parietal lobe used to restrict the functional connectivity analysis. Slice locations in Montreal neurological institute space are indicated on the top right of each axial slice. Contra, contralateral to affected limb; dl, dorsolateral; SMA, supplementary motor area; vl, ventrolateral
