Figure 6.

Area under the curve (AUC) in adolescent (postnatal day [PND] 25–53, left panel) and adult (PND 75–103, right panel) rats with free access to either standard or high fat chow or restricted access to high fat chow and tested once per week with cocaine for 4 weeks. Each symbol represents the mean ±SEM of 6 rats (same data as plotted in Figure 4). Abscissa: PND age in days. Ordinate: mean AUC (±SEM). *P<.05 compared with rats that had free access to standard chow throughout the study at the corresponding age. #P<.05 compared with the same rats when they had free access to standard chow at the beginning of the study (i.e., PND 25 or 75).
