Extended Data Fig. 12. Regions undergoing significant morphological changes from 22 to 31 weeks’ gestation.

Statistical maps from our non-parametric analysis of temporal change, overlayed on a set of axial views from bottom (near the cerebellum) to top of the cerebral space. Maps highlight voxel clusters that survived the conservative threshold of $p<0.05$, shown here for two-week intervals between 22- and 31-weeks’ gestation. Red indicates regions in which the relative (normalised) volume is greater in the younger subgroup ($a$) than in the older subgroup ($a+2$), and vice-versa for blue regions. This figure supports results shown in Fig. 4 of the main text.
