Regions of increased WM volumes in stutterers. Indicated are the peak differences (in t-values), their stereotactically coordinates, and the associated anatomical labels derived from the MNI standard brain. Please note, there were no areas with increased WM volumes in controls compared to stutterers.

R Inferior frontal gyrus (IFG)	66	8	21	6.58
R Middle frontal gyrus (MFG)	44	48	11	6.23
R Precentral gyrus (PrCG)	30	-28	63	7.25
R Precentral gyrus (PrCG)	62	-12	37	6.53
