Figure 2From: Effects of a selectively bred novelty-seeking phenotype on the motivation to take cocaine in male and female rats BPs on a PR schedule of reinforcement for bHR and bLR males and females using an expanded range of doses of cocaine (Experiment 2). *P < 0.05, significant effect of phenotype within sex at that dose. # P < 0.05, statistically significantly different from the lowest dose (#1) or the middle dose (#2) within sex and phenotype.Back to article page
