Intraperitoneal injections of low doses of apomorphine, a dopaminergic receptor agonist, depressed briefly, and then enhanced self-stimulation behaviour in the dorsal area of lateral hypothalamus. In contrast, only depressant effects were observed in the ventral area. These differential effects suggest the presence of a dopaminergic componant in the dorsal hypothalamic self-stimulation system.
腹腔注射低剂量的阿扑吗啡（一种多巴胺能受体激动剂），会使下丘脑外侧背侧区域的自我刺激行为先短暂受到抑制，然后增强。相比之下，在下丘脑腹侧区域仅观察到抑制作用。这些不同的效应表明下丘脑背侧自我刺激系统中存在多巴胺能成分。
