Brain regions are shown in figure 3a.
A. 29 genes are expressed in the early-mid pre-natal period (4-24 post-conception weeks)
B. 15 genes are expressed throughout development; subclusters correspond to either specific expression in region 4, or expression across the brain
C. Ten genes are expressed in the late-prenatal (25-38pcw) and post-natal period
D. 12 genes are expressed in the late pre-natal period (25-39pcw)
