Pre- (left panel) and post (right panel)-surgery fMRI maps for tongue movements (A), object naming (B), verb naming (C), and word/pseudoword reading (D) tasks. Activations are superimposed on the T2-weighted MRI axial slices of the patient.

In addition, posterior temporal activation was found in the back of the lesion, bilaterally, and bilateral activation in the Rolandic operculum was found just in front of the lesion (see Figure 3). As to streamlines, we found that the number of streamlines of the patient for the left corticospinal tract was significantly lower than controls, while it was significantly higher for the right corticospinal tract (see Figure 4 and Table 3).
Pre- (left panel) and post (right panel)-surgery DTI reconstructions of the inferior fronto-occipital fasciculus (A), superior longitudinal fasciculus (B), and corticospinal tract (C). Plots (D) represent mean fractional anisotropy (FA) and the number of streamlines for the patient and healthy controls.

As to streamlines, we found that the number of streamlines of the patient for the left corticospinal tract was significantly lower than controls, while it was significantly higher for the right corticospinal tract (see Figure 4 and Table 3). The analysis revealed that FA of the left SLF was significantly lower than controls, while the FA of the right corticospinal tract and of the right IFOF was significantly higher than controls (Figure 4).
