A. Glass brain with arrow in the right PMRG
B. Anatomical localization of bilateral GMV reduction in PMRG in BPI. Right: cluster size 19 voxels, z=3.2, P=0.015 (x=12, y=14, z=−21). Left: cluster size 19 voxels, z=3.31, P=0.01 (x=−13, y=12, z=−21).
C. Mean and standard deviation of PMRG GMV in BPI and HC.
BPI: patients with bipolar disorder type I, HC: healthy controls. SE: standard error of the mean. Statistical threshold=P<0.05, using small volume correction
