Figure 4:

Critical white matter connections of the language systems. (A) Sagittal and (B) inferior axial MR tractography images show the relationship of several of the primary connections of the language system. The ventral semantic stream primarily consists of the inferior fronto-occipital fasciculus (purple), inferior longitudinal fasciculus (green), and uncinate fasciculus (red). The dorsal phonologic stream primarily consists of the arcuate fasciculus (pink) and the lateral portion of the superior longitudinal fasciculus (cyan). The frontal aslant tract (yellow) connects the frontal opercular language areas with the presupplementary motor area and is a critical component of verbal fluency.
