Two-way ANOVA revealed a significant effect of stress on 5-HIAA content in both the anxiety-promoting DRD and the panic-inhibiting DRVL/VLPAG projection sites [BLA: F(1, 22) = 18.0, p<0.001, PrL: F(1, 20) = 4.6, p = 0.045, IL: F(1, 20) = 9.5, p = 0.006, DLPAG: F(1, 20) = 10.2, p = 0.005; Figure 4]. This evidence concerns the gene PRL and Anxiety.
