Mice of the C57BL/6J strain became hyperactive to increasing doses of morphine sulfate. This response was similar to locomotor hyperactivity induced by amphetamine. Lesions and chemical blockade of posterior n. accumbens abolished amphetamine-induced hyperactivity and reduced but did not abolish the morphine response. These experiments demonstrate that the response to the two drugs is mediated by overlapping but noncongruent neural systems.
C57BL/6J品系的小鼠对递增剂量的硫酸吗啡变得多动。这种反应类似于苯丙胺诱导的运动性多动。伏隔核后部的损伤和化学阻断消除了苯丙胺诱导的多动,并减弱了但并未消除吗啡反应。这些实验表明,对这两种药物的反应是由重叠但不完全相同的神经系统介导的。
