Fig. 3: Transcriptomic gene analysis of cortical samples reveals that myelination and synaptic processes are cellular mechanisms of postnatal development.

a Matrix showing gene expression levels in prenatal (19 post conceptual weeks (pcw) to 37 pcw) and postnatal (4-months-old) cortical tissue samples for the 95 most differentially expressed genes. Nprenatal tissue donors = 7; Npostnatal tissue donors = 3. Sample demographics in Supplementary Table 6. Rows: genes, columns: cortical area (acronyms in Supplementary Table 7); color: expression level in reads per kilobase million (RPKM, see colorbar). b Gene expression fold change (FC) between postnatal vs. prenatal cortical samples of the 95 most differentially expressed genes. c Gene enrichment analysis showing the molecular and biological processes and cellular components related to these 95 genes.
