"The superior longitudinal fasciculus has three distinct branches (Petrides and Pandya, 1984).
In humans, the first branch of the superior longitudinal fasciculus (SLF I) connects to the superior parietal lobule and precuneus (BA 5 and 7), to the superior frontal (BA 8, 9, 32) and perhaps to some anterior cingulate areas (BA 24). The second branch (SLF II) originates
in the anterior intraparietal sulcus and the angular gyrus (BA 39 and 40) and terminates in the posterior regions of the superior and middle frontal gyrus (BA 6, 8, 9). The third branch (SLF III) connects the intraparietal sulcus and inferior parietal lobule to the inferior frontal gyrus (BA 44, 45, 47)"
