FIGURE 3.

Two major components of cortical gene expression. Top and middle panels (Component 1 and Component 2, respectively) left: Regional z scores mapped to the cerebral cortex (scaled for each hemisphere) and right: word clouds of the statistical over‐representation results. The relative direction of component scores is arbitrary (dictated by the PCA), and here, the colour scale is flipped between components so that the directions of upregulation/downregulation match. Bottom panel: Density distribution plots of loadings on Component 1 and Component 2 coloured by cell type.
