标题： Modularity, Hierarchical Flows and Symmetry of the Drosophila Connectome

摘要： 本报告研究了果蝇连接组中中央区域的模块化组织。 我们利用Infomap识别出神经元组群，在这些组群内信息可以快速流通，然后传播到网络的其余部分。 我们发现信息沿着连接遥远神经元的路径流动，形成了跨越整个大脑的模块。 值得注意的是，这些模块仅基于神经元的连接模式得出，显示出明显的左右对称性，不仅在空间分布上如此，在连接方式上也是如此。 我们还在这类模块的粗粒度尺度上确定了一种层次结构，证明了系统中信息流的方向性。 显示英文摘要

摘要： This report investigates the modular organisation of the Central region in the Drosophila connectome. We identify groups of neurones amongst which information circulates rapidly before spreading to the rest of the network using Infomap. We find that information flows along pathways linking distant neurones, forming modules that span across the brain. Remarkably, these modules, derived solely from neuronal connectivity patterns, exhibit a striking left-right symmetry in their spatial distribution as well as in their connections. We also identify a hierarchical structure at the coarse-grained scale of these modules, demonstrating the directional nature of information flow in the system.
