Figure 5From: Attenuation by dextromethorphan on the higher liability to morphine-induced reward, caused by prenatal exposure of morphine in rat offspringEffects of morphine (1 mg/kg) on the dopamine turnover rate ([DOPAC+HVA]/[DA]) of the male offspring rats (p60) from different groups in the (A) nucleus accumbens (NAc), (B) dorsal striatum (DS), (C) medial prefrontal cortex (mPFC), and (D) olfactory tubercle (OT). Data were presented as means ± SEM. One-way ANOVA followed by Newman-Keuls test was used to analyze the data (*p < 0.05 for the morphine group vs. the control group; #p < 0.05 for the M + DM group vs. the morphine group; n ≧ 6).Back to article page
