The biological bases of wanting have been characterized in mammals, but whether an equivalent wanting system exists in insects remains unknown. In this study, we focused on honey bees, which perform intensive foraging activities to satisfy colony needs, and sought to determine whether foragers leave the hive driven by specific expectations about reward and whether they recollect these expectations during their waggle dances. We monitored foraging and dance behavior and simultaneously quantified and interfered with biogenic amine signaling in the bee brain. We show that a dopamine-dependent wanting system is activated transiently in the bee brain by increased appetite and individual recollection of profitable food sources, both en route to the goal and during waggle dances. Our results show that insects share with mammals common neural mechanisms for encoding wanting of stimuli with positive hedonic value.
在哺乳动物中，欲望的生物学基础已得到明确，但昆虫是否存在类似的欲望系统仍不清楚。在本研究中，我们聚焦于蜜蜂，它们会进行高强度的觅食活动以满足蜂群需求，并试图确定觅食者离开蜂巢是否受对奖励的特定预期驱使，以及它们在摇摆舞期间是否会回忆起这些预期。我们监测了觅食和舞蹈行为，同时对蜜蜂大脑中的生物胺信号进行了量化和干扰。我们发现，在前往目标的途中以及摇摆舞期间，食欲增加和对有利可图食物来源的个体回忆会使蜜蜂大脑中一个依赖多巴胺的欲望系统短暂激活。我们的结果表明，昆虫与哺乳动物共享用于编码对具有积极享乐价值刺激的欲望的共同神经机制。
