MNI stereotactic coordinates of the local maxima of regions showing an effect of reaching and grasping with the right hand (both the common and differential effects of monocular and binocular viewing conditions are listed). For large clusters spanning several anatomical regions, more than one local maximum is given. Cluster size is given in number of voxels. Statistical inference (p < 0.05) was performed at the voxel level, correcting for multiple comparisons using the false-discovery rate approach over the search volume. IV–VI, Cerebellar hemisphere IV to VI; V1, visual area 1; V2, visual area 2; V3, visual area 3; V5, visual area 5.
