The average gene expression levels across the three brain regions are presented in Supplementary Table S1; data are provided for the Ensembl annotated “genes” (N = 42,282). In all regions approximately 15,000 “genes” met the threshold of one CPM reads. Genes showing at least a 10-fold difference in expression between two regions are also found in Supplementary Table S1. Some expected examples include the high expression of Adora2, Penk, and Drd2 in the CeA and SH and the high expression of Bdnf and Cck in the PL.
