Figure 3.
Comparison of average FA between two groups. The PD + CCPS group exhibited decreased structural connectivity compared with the PD - CCPS group in the fiber connecting the left insula and left SMA (red nodes and red thick lines; p = 0.019). No significant differences in the other fibers were found between the two groups (p > 0.05; yellow nodes and yellow thin lines). SMA.L: left supplementary motor area; SMA.R: right supplementary motor area; INS.L: left insula; INS.R: right insula; SFGdor.L: left dorsal superior frontal gyrus; SFGdor.R: right dorsal superior frontal gyrus; MFG.L: left middle frontal gyrus; MFG.R: right middle frontal gyrus; ORBinf.L: orbital part of left inferior frontal gyrus; ORBinf.R: orbital part of right inferior frontal gyrus.
