Functional enrichment of overlapping and distinct sets of differentially expressed genes in the nucleus accumbens (NAc). In (A), the number of differentially expressed genes overlapping or distinct between fathers and virgin males in the NAc is depicted. For each set, the functional enrichments in gene ontologies of the biological processes (B), cellular components (C), and molecular functions (D) categories are displayed. ***p < 0.001, hypergeometric test for overlap between two sets of genes
