Network of hub genes of module M3. Each hub gene is displayed with its top twenty-five co-expressed genes connected either by dotted lines or bold dashed lines for ARRDC2. Genes expressed in the Hip are shown in blue and genes expressed in the Hyp in red; hub genes are highlighted in dark blue and red, respectively. ENSSSCG00000038594 and ENSSSCG00000005949 are tentatively annotated as sdc4 and sla, respectively, labeled in small letters. Hip, hippocampus; Hyp, hypothalamus.
