人脑由支持认知的功能专门系统组成。最近，我们提出了一种以边缘为中心的模型来检测重叠社区。目前尚不清楚这些群落和大脑系统如何相关。在这里，我们使用午夜扫描俱乐部的数据来解决这个问题，并表明所有大脑系统都通过至少两个边缘社区连接。然后，我们检查每个系统内边缘社区的多样性，发现异模态系统比感觉系统更加多样化。接下来，我们对整个皮层进行聚类，以根据区域的边缘社区概况来揭示它。我们发现异模态系统中的区域更有可能形成自己的集群。最后，我们表明边缘社区是个性化的。我们的工作揭示了整个皮层边缘群落的普遍重叠及其与大脑系统的关系。我们的工作为未来使用以边缘为中心的大脑网络进行研究提供了途径。
The human brain is composed of functionally specialized systems that support cognition. Recently, we proposed an edge-centric model for detecting overlapping communities. It remains unclear how these communities and brain systems are related. Here, we address this question using data from the Midnight Scan Club and show that all brain systems are linked via at least two edge communities. We then examine the diversity of edge communities within each system, finding that heteromodal systems are more diverse than sensory systems. Next, we cluster the entire cortex to reveal it according to the regions' edge-community profiles. We find that regions in heteromodal systems are more likely to form their own clusters. Finally, we show that edge communities are personalized. Our work reveals the pervasive overlap of edge communities across the cortex and their relationship with brain systems. Our work provides pathways for future research using edge-centric brain networks.
