(a) Biological processes over-represented in differentially expressed genes in the hippocampus between schizophrenia cases and controls and (b) heat map of differentially expressed genes related to defence response. Enrichment map for differentially expressed genes in the hippocampus between schizophrenia and controls and the heat map were generated with the Enrichment Map Plugin³⁴ for Cytoscape programme.⁸¹ Nodes represent functional groups of gene sets and edge thickness is proportion to the overlap between gene sets in the enrichment map.
