It was also of interest to identify genes with module membership that differed substantially between brain regions, as such genes may shed light on regional differences involving particular cell types or functional processes in the human brain (genes with the most significant differences in module membership between CTX, CN and CB for M9, M15 and M16 are reported in Supplementary Table 10 online and complete results for all genes and all conserved modules are presented in Supplementary Table 11 online; Methods).
