We constructed a set of temporally-densely
sampled cortical surface atlases for characterizing the dynamic fetal brain cortex expanding from the 22 to 36
gestational weeks.
Fig. 1. The constructed fetal cortical surface atlases (left
hemisphere) at different gestational weeks (GW). The number in the bracket
indicates the subject number for construction the atlas at the time point. (a)
The sulcal depth on the spherical surface. (b) The average convexity on the
spherical surface. (c) The mean curvature on the spherical surface. (d) The
sulcal depth on the inner cortical surface. (e) The average convexity on the
inner cortical surface. (f) The mean curvature on the inner cortical surface. (g)
The Desikan parcellation on the inner cortical surface.

different gestational weeks, in both the left and right hemisphere.
