GPER-Deficient Rats Exhibit Lower Serum Corticosterone Level and Increased Anxiety-Like Behavior

Figure 5

Distribution of the reporter gene (Tomato) in the hippocampal formation of the GPER reporter mice. Tomato⁺ neuronal cell bodies (white arrows) are localized in the dentate gyrus (DG) but not in the hilum, CA3, CA2, or CA1 regions, where Tomato⁺ fibers and terminal boutons (green arrows) are numerous.
