Accordingly, diffusivity differences in the superior cerebellar peduncle (SCP) showed a trend with tool use (ASD group, AD: p = 0.051), supporting the notion that alterations of the SCP may be related to motor deficits rather than clinical group membership, in contrast to the decreased diffusivities of the middle cerebellar peduncle, which may be more related to autism core symptomatology.
