Consistent temporal expression patterns of apoptotic genes during development in three different brain regions: (a) Clustering heatmaps of apoptotic gene mRNA expression in the midbrain and hindbrain. Gene clusters with the dendrogram are labeled on the right to the heat maps. (b) Venn diagrams of downregulated genes and upregulated genes defined by hierarchical clustering separately performed for three brain regions, showing substantial overlaps among the three brain regions.
