Preprocessing pipeline and the tractography visualization. (A) In the upper row, we introduce the key points of structural connectivity construction. (B) left: The tracts seeded in region A and leading to three example ROIs B, C, and D are shown. The elements in the first row of the connectivity matrix are proportional to the number of streamlines originating in A and entering the corresponding ROIs. (B) right: The same procedure with a focus on the seeds in region B.
