From: Attenuation by dextromethorphan on the higher liability to morphine-induced reward, caused by prenatal exposure of morphine in rat offspring

Figure 2

Effect of morphine (1 mg/kg) to induce rewarding in the male offspring rats (p60) from different groups, which was measured by conditioned place preference (CPP) tests (A: Control group; B: Morphine group; C: M + DM group; D: DM group). Data were expressed as preference for the drug-paired compartment, which was determined by time spent in the drug-paired compartment minus time spent in the saline-paired compartment. Data were presented as mean ± SEM., and paired t-test was used to analyze the data (**p < 0.01 for day 6 vs. day 0; n 8).
