Visual representation of connections of genes in Red module. This figure shows target genes of the probes in the Red module with the strongest connections only (r > 0.92). Circles (○) denote genes with increased expression levels in hippocampus and diamonds (◊) represent genes with increased expression levels in the amygdala. Node size is related to the number of connections of that particular gene; a highly connected gene (i.e. 'hub gene') is therefore larger than genes with fewer connections. Nodes are colored blue when they appear in the Ingenuity categories Neurological Disease, Genetic Disorder and Psychological Disorder. Green nodes represent the genes unique to the Genetic Disorder category. Edge length is not related to correlation strength.
