Neural activity decrease associated with knee flexion force error
2	R Precuneus, Postcentral gyrus, Posterior cingulate gyrus, Superior parietal lobule	257	0.00138	6	−40	50	5.91

Regions of brain activity are reported that were identified in FSLeyes with the Harvard-Oxford cortical and subcortical structural atlas, Julich histological atlas, and the cerebellar atlas in MNI152 space after normalization with FNIRT by peak voxel and with FSL tool atlasquery. There was no significant increased neural activity associated with knee flexion error. B, bilateral; L, left; R, right.
