The Plasticity of Brain Gray Matter and White Matter following Lower Limb Amputation

Table 3

The differences of FA values in fiber tracts generated from tractography.

Region	Cluster index	FA value		value
		Controls	Patients
WM connecting bilateral PMC	3	0.48 ± 0.02	0.44 ± 0.04	0.009
Right IFOF	2	0.47 ± 0.03	0.45 ± 0.02	0.009
WM underlying left PMC	1	0.36 ± 0.02	0.33 ± 0.02	0.0003

The value was adjusted for multiple comparisons. IFOF, inferior frontooccipital fasciculus; PMC, premotor cortex; WM, white matter.
