Fig. 4: Summary of the Pearson coefficient values between the analyzed phenotypical traits and gene expression levels.

Matrix displays the correlations between the behavioral phenotype (social preference from the social interaction test and latency to eat from the novelty suppressed feeding test) and IEGs expression in the prefrontal cortex (PFC), ventral hippocampus (VH), dorsal hippocampus (DH), and amygdala (Amy) in male (top panel) and female (bottom panel) rats, considering the overall effect of prenatal stress exposure (PNS) or the vulnerable (PNS-vul) and resilient (PNS-res) subgroups. Genes are shown individually (Arc, Npas4, Zif-268, Cfos) and as a global activation score (Z-score). Blue indicates positive correlations while red indicates negative correlations. Significant correlations are reported as *p < 0.05.
