Module overlap across brain regions together with enrichment of modules in DE/DV/DW genes. Color from blue to red is proportional to –log10(p) of overlap between module membership (Fisher exact test). A majority of modules have strong counterparts across regions. The affected modules also have an affected counterpart in a majority of cases, although we also find region specific affected modules. (A) CeA – SH; (B) CeA – PL; (C) SH – PL.
