Significant voxel clusters of left-right interhemispheric differences from the voxel-wise general linear model analysis.

Also shown are results from the co-variates “Age” and “Grey matter volume”. Voxels: number of voxels in significant cluster. Z-max: maximum Z value of most significant voxel. X, Y, Z: Montreal Neurological Institute coordinates of most significant voxel. LI: Laterality Index based on the region-of-interest analysis, see Methods. NA: Not applicable.
