Number of white matter (WM) streamlines, tract volume and apparent fiber density (AFD) in control and patient tracts: A) Mean number of streamlines in WM tracts (corticospinal (CST), somatosensory (Somato), cortico-ponto-cerebellar (CPC), cerebellar-thalamo-cortical (CTC)) (left (L) and right (R) ± pointwise 95% confidence interval) is plotted with significance (*, p < 0.006). B) The mean AFD in WM tracts (left (L) and right (R) ± pointwise 95% confidence interval) is plotted with significance (*, p < 0.006). C) The mean tract volume (mL) in WM tracts (left (L) and right (R) ± pointwise 95% confidence interval) is plotted with significance (*, p < 0.006). D) The mean AFD in WM tracts (left (L) and right (R) ± pointwise 95% confidence interval) corrected for partial volume effects is plotted with significance (*, p < 0.006).
