Table 1. Summary of ΔFosB expression in sexually naïve and experienced animals.
Semi-quantitative analysis of ΔFosB expression in sexually naïve and experienced animals (n=5 each group). Numbers of ΔFosB-IR cells were rated using the following scale: − (absent; 0–1 cell), + (low; 2–10 cells), ++ (10–50 cells), +++ (50–100 cells) and ++++ (highest; >100 cells).
