Fig. 2. Surface area and fiber distance distributions for the fetal surfaces.

(A) The adult brain is warped into the shape of the fetal brain at each GA time point (see Fig. 1B), allowing our node parcellation to be projected through developmental time. (B) Surface area estimated using the inner white/gray boundary of the left hemisphere of each fetal brain, with the adult included for comparison. (C) Kernel density plots of internodal fiber distances between all nodes at each developmental time point.
