Regions of increased fractional anisotropy in ASD. Individuals with ASD diagnoses showed significantly (TFCE p < 0.05) increased measures of fractional anisotropy (FA) across eight clusters (Table 2) highlighted above. Indicated white matter tracts include regions of the corpus callosum, corona radiata, and inferior and superior longitudinal fasciculi as well as the middle and superior cerebellar peduncles and corticospinal tract. Images are presented in R/L radiological convention with MNI z coordinates in millimeter. Skeletonized statistical overlays have been “inflated” for display
