Compared with diet control, acupuncture increase grey matter volume in  physiological and psychological brain regions, where the impact on functional connectivity is even lighter after therapy. Acupuncture is likely to improve endocrine while reducing the pressure of weight loss.
Figure 1. (i) Regions wherein GMV are significantly increased after acupuncture. The centers of 3 ROIs are MNI space coordinates of these clusters’ peak voxel (ROI 1: (-38, -72, -35); ROI 2: (-5, -54, 8); ROI 3: (39, -41, 66)). (ii) Regions wherein GMV are significantly increased after diet control therapy. The centers of 2 ROIs are the MNI space coordinates of these clusters’ peak voxel (ROI 4: (18, -9, -38); ROI 5: (-30, 47, 27)). P: Posterior; A: Anterior. Results (scan 2 – scan 1) are reported with a threshold of p < 0.001 (uncorrected) on the voxel level and a cluster extent > 30 voxels.
Figure 2. The results of FC with 5 ROIs after acupuncture. A: Row 1 is the region wherein FC with ROI 2 are significantly increased and row 2 is the region wherein FC are decreased. B: The region wherein FC with ROI 3 are significantly decreased. C: The region wherein FC with ROI 4 are significantly increased. D: The region wherein FC with ROI 5 are significantly increased. L: Left; R: Right. Results (scan 2 – scan 1) are reported with a threshold of p < 0.001 (uncorrected) on the voxel level and a cluster extent ≥ 5 voxels.
