a
Marks the components plotted in Figure 6.
b
IC12 and IC6 have overlaps with uncinate fasciculus 17.4% and 14.1%.
c
Marks the tracts not covered by JHU atlas (<20% overlap), which visually identified as commissural fibers across corpus callosum. ‘Fiber type’ is labeled based on the actual tract trajectory.
