Dynamic transcriptomic basis of structural connectome was studied by associating spatiotemporal transcriptome map from over 10,000 genes and diffusion-MRI-derived structural network through the 3rd trimester and early childhood.
Figure 1. The schematic pipeline of construction of connectome trajectory (in pink) and its association (in green) with gene expression (in blue) from the 3rd trimester to 8 years of age. Abbreviations: PLS = partial least squares; MFC = medial prefrontal cortex; V1C = primary visual cortex.
Figure 4. Gene enrichment analysis in top 10% genes associated with degree centrality demonstrated dynamic enrichment in (A) different cell types and (B) gene ontology terms for biological process through the 3rd trimester and early childhood. Significance is labeled by color (red dot: p<0.05; gray dot: p≥0.05, FDR corrected). Abbreviations: Ex=excitatory; In=inhibitory neuron; Other=other types of cells in brain. Ex2b and Astro1 are subtypes of excitatory neuron and astrocyte, respectively.
