Relationship between bilateral putamen and globus pallidus volumes and the strength of connectivity between left M1 and the right precentral gyrus (r=0.412, p=0.0040; r=0.402, p=0.0051, respectively), right cuneus (r=0.372, p=0.0099; r=0.325, p=0.0256), left cuneus (r=0.406, p=0.0046; r=0.377, p=0.0091), and posterior cingulate (r=−0.414, p=0.0038; r=−0.505, p=0.0003).
