FA maps of the left dorsal stream (SLF) of the control, nfvPPA, and svPPA groups overlaid on a standard MNI brain. Only voxels present in at least 20% of the participants are shown. Lower FA values are represented in violet-blue, and higher values are represented in yellow-red.

FA maps of the left ventral stream (ILF and uncinate) of the control, nfvPPA, and svPPA groups overlaid on a standard MNI brain. Only voxels present in at least 20% of the participants are shown. Lower FA values are represented in violet-blue, and higher values are represented in yellow-red.

Significant partial correlations between connected speech features and DTI metrics for each patient group. There are extreme values for 2 svPPA patients. Nonetheless, the data from these two patients were kept after a close look at all the DTI metrics as well as the neuropsychological and language evaluations, which did not suggest that these 2 patients were outliers. UNC = Uncinate.
