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. B, bilateral; L, left; R, right.
