摘要

以不同分辨率采集的大脑记录支持不同的神经编码特征,从而产生了规模依赖性的大脑功能理论。在这里,我们展示了这些不同的特征,它们来自于在斑马鱼和线虫的整个大脑以及果蝇、小鼠和猕猴的感官区域收集到的钙成像记录中观察到的神经元活动的重尾多尺度功能组织。网络模拟证明,这种保守的分层结构能增强信息处理能力。最后,我们发现,尽管在行为过程中细胞协调发生了显著的跨尺度重构,但这种组织结构仍然得以维持。我们的研究结果表明,神经元活动的这种非线性组织是一种普遍原则,它能够在多个时空尺度上将行为与神经动态适应性地联系起来,同时兼顾功能恢复能力和信息处理效率,因此得到了保护。

Multiscale organization of neuronal activity unifies scale-dependent theories of brain function
Brain recordings collected at different resolutions support distinct signatures of neural coding, leading to scale-dependent theories of brain function. Here, we show that these disparate signatures emerge from a heavy-tailed, multiscale functional organization of neuronal activity observed across calcium-imaging recordings collected from the whole brains of zebrafish and C. elegans as well as from sensory regions in Drosophila, mice, and macaques. Network simulations demonstrate that this conserved hierarchical structure enhances information processing. Finally, we find that this organization is maintained despite significant cross-scale reconfiguration of cellular coordination during behavior. Our findings suggest that this nonlinear organization of neuronal activity is a universal principle conserved for its ability to adaptively link behavior to neural dynamics across multiple spatiotemporal scales while balancing functional resiliency and information processing efficiency.

期刊介绍: Cells is an international, peer-reviewed, open access journal that focuses on cell biology, molecular biology, and biophysics. It is affiliated with several societies, including the Spanish Society for Biochemistry and Molecular Biology (SEBBM), Nordic Autophagy Society (NAS), Spanish Society of Hematology and Hemotherapy (SEHH), and Society for Regenerative Medicine (Russian Federation) (RPO). The journal publishes research findings of significant importance in various areas of experimental biology, such as cell biology, molecular biology, neuroscience, immunology, virology, microbiology, cancer, human genetics, systems biology, signaling, and disease mechanisms and therapeutics. The primary criterion for considering papers is whether the results contribute to significant conceptual advances or raise thought-provoking questions and hypotheses related to interesting and important biological inquiries. In addition to primary research articles presented in four formats, Cells also features review and opinion articles in its "leading edge" section, discussing recent research advancements and topics of interest to its wide readership.
