Recent studies have shown that the neural regulation of pair bonding in the monogamous prairie vole (Microtus ochrogaster) is similar to that of drug seeking in more traditional laboratory rodents. Therefore, strong interactions between social behavior and drug reward can be expected. Here, we established the prairie vole as a model for drug studies by demonstrating robust amphetamine-induced conditioned place preferences in this species. For both males and females, the effects of amphetamine were dose-dependent, with females being more sensitive to drug treatment. This study represents the first evidence of drug reward in this species. Future studies will examine the effects of social behavior on drug reward and the underlying neurobiology of such interactions.
最近的研究表明,一夫一妻制的草原田鼠(Microtus ochrogaster)中配偶关系的神经调节与更传统的实验啮齿动物中寻求药物的神经调节相似。因此,可以预期社会行为与药物奖赏之间会有强烈的相互作用。在这里,我们通过证明安非他命在该物种中能强烈诱导条件性位置偏爱,从而将草原田鼠确立为药物研究的模型。对于雄性和雌性而言,安非他命的作用呈剂量依赖性,雌性对药物治疗更敏感。这项研究是该物种中药物奖赏的首个证据。未来的研究将考察社会行为对药物奖赏的影响以及此类相互作用的潜在神经生物学机制。
