Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. Regardless of species, insects share the presence of a group of morphologically conserved neuropils known collectively as the central complex (CX). The CX is a navigational center, involved in sensory integration and coordinated motor activity. Despite the fact that our understanding of navigational behavior comes predominantly from ants and bees, most of what we know about the underlying neural circuitry of such behavior comes from work in fruit flies. Here we aim to close this gap, by providing the first comprehensive map of all major columnar neurons and their projection patterns in the CX of a bee. We find numerous components of the circuit that appear to be highly conserved between the fly and the bee, but also highlight several key differences which are likely to have important functional rami1cations.

大黄蜂中央复合体的投影组


昆虫已经进化出多样化且卓越的策略来在世界各地的各种生态中导航。无论何种物种，昆虫都存在一组形态保守的神经纤维，统称为中央复合体 (CX)。 CX 是一个导航中心，参与感觉统合和协调运动活动。尽管我们对导航行为的理解主要来自蚂蚁和蜜蜂，但我们对这种行为的潜在神经回路的了解大部分来自对果蝇的研究。在这里，我们的目标是通过提供第一个关于所有主要柱状神经元及其在蜜蜂 CX 中的投影模式的综合图来缩小这一差距。我们发现果蝇和蜜蜂之间的电路的许多组件似乎高度保守，但也强调了可能产生重要功能影响的几个关键差异。
