Fig. 6: Lateral view of the left hemisphere lesion of patient TA.

The area invaded by the lesion is marked with the yellow color and involves mostly the parietal lobe, including some adjacent posterior temporal and occipital areas. Thus, the lesion is restricted to the dorsal posterior language network, sparing all cortical areas associated with the ventral language network, such as the pars triangularis (area 45) of the inferior frontal gyrus and the anterior temporal areas. The lesion was reconstructed in MNI stereotaxic space and projected on the standard average MNI brain65,66. Abbreviations: ANG angular gyrus; csts1 caudal superior temporal sulcus, first segment; csts2 caudal superior temporal sulcus, second segment (angular sulcus); csts3 caudal superior temporal sulcus, third segment (anterior occipital sulcus); ips intraparietal sulcus; ips-po intraparietal sulcus, paroccipital segment; lf lateral fissure; pSTG posterior superior temporal gyrus; PoG postcentral gyrus; SMG supramarginal gyrus; spcs superior postcentral sulcus; sps superior parietal sulcus.
