Compared to the normal controls (NCs), significantly lower fractional anisotropy (FA) values were observed in the left angular gyrus (AG), right cerebellum (CB), left precentral gyrus (PreCG), left lateral occipital region (LOC), left superior longitudinal fasciculus (SLF), left supramarginal gyrus (SMG), and left postcentral gyrus (PostCG) in SCI patients (p < 0.01, TFCE corrected) (Table 2 and Figure 1).
Brain White Matter Impairment in Patients with Spinal Cord Injury
The inferior longitudinal fasciculus (ILF) and inferior fronto-occipital fasciculus (IFOF) are still classically described as the two main white matter bundles responsible for facilitating the epileptic propagation in OLE because of their close spatial relationship with the optic radiation and the primary visual cortex (V1) [18, 20].

Thus, for example, the left posterior inferior frontal region, Broca's area, was linked to speech production (where brain damage would result in articulatory problems); the left posterior temporal region, Wernicke's area, to auditory speech recognition (where damage would yield impaired language comprehension); and the arcuate fasciculus connecting these anterior and posterior regions to repetition (where damage would impair production by repetition but preserve comprehension).
