Trajectory and termination of the Arcuate Fasciculus segments on DTI. The ventral segment (blue) connects the middle and posterior parts of the superior temporal gyrus and the middle part of the middle temporal gyrus, to the ventral premotor cortex and pars opercularis and triangularis by passing deep to the supramarginal gyrus. The dorsal segment (orange) connects the posterior part of the middle and inferior temporal gyri to the pars opercularis, ventral premotor cortex, and posterior part of the middle frontal gyrus by passing deep to the angular gyrus. (Image courtesy of AL Rhoton, Jr.)
