Contrasting results between post-acupuncture functional connectivity and pre-acupuncture functional connectivity for three groups. The voxel-wised functional connectivity analysis was conducted using the PCC/pC as a seed point. The paired t-test compared the sustained effects with the baseline, i.e, RUN 31 v.s. RUN1 and RUN 32 v.s. RUN1) and the results were thresholded at P < 0.005 (uncorrected) and the cluster size > 5 voxels. Warm (cold) colors indicated the increase (decrease) in functional connectivity.
