为了解构大脑回路的结构和功能,有必要在整个大脑范围内生成神经元连接和活动的地图。新的方法现在能够以细胞和亚细胞分辨率对小鼠大脑进行大规模绘图。我们开发了一个框架来自动注释,分析,可视化,并轻松地共享全脑数据在细胞分辨率,基于尺度不变和交互式小鼠大脑图谱。该框架能够在各个实验室中跨成像平台进行连接和映射项目,以及关于单个神经元分子身份的多路复用定量信息。作为概念的证明,我们生成了皮质纹状体回路中五种主要神经元类型的比较连接图,以及基于活动的地图,以确定介导可卡因行为效应的枢纽。因此,这种计算框架提供了必要的工具来生成整合了连接性、神经元身份和功能数据的脑图。
To deconstruct the architecture and function of brain circuits, it is necessary to generate maps of the neuronal connectivity and activity on a whole brain scale. New methods now enable large-scale mapping of the mouse brain at cellular and subcellular resolution. We developed a framework to automatically annotate, analyze, visualize, and easily share whole-brain data at cellular resolution, based on a scale-invariant and interactive mouse brain atlas. This framework enables connectivity and mapping projects in individual laboratories, across imaging platforms, as well as multiplexed quantitative information on the molecular identity of single neurons. As a proof of concept, we generated a comparative connectivity map of five major neuron types in the corticostriatal circuit, as well as an activity-based map to identify hubs mediating the behavioral effects of cocaine. Thus, this computational framework provides the necessary tools to generate brain maps that integrate data from connectivity, neuron identity and function.
