果蝇的中枢复合体中有几百个神经元组成的网络,与哺乳动物的头部方向系统类似,可以估计果蝇在世界上的方向。在这里,我们描述了解剖学上定义的神经类如何在这个网络中准备实现特定的子过程来构建和更新这个群体水平的标题信号。我们在果蝇中央复合体中描述的计算非常类似于在哺乳动物大脑中存在的计算模型,用于构建头部方向信号。通过将回路解剖学与导航生理学联系起来,果蝇的中枢复合体应该提供了首个关于头部信号如何形成的详细例子。
A network of a few hundred neurons in the Drosophila central complex carries an estimate of the fly’s heading in the world, akin to the mammalian head-direction system. Here we describe how anatomically defined neuronal classes in this network are poised to implement specific sub-processes for building and updating this population-level heading signal. The computations we describe in the fly central complex strongly resemble those posited to exist in the mammalian brain, in computational models for building head-direction signals. By linking circuit anatomy to navigational physiology, the Drosophila central complex should provide the first detailed example of how a heading signal is built.
