320-小鼠单神经元连接组的多模态重建

from 聊聊Sci

这项研究提出了一个可扩展的框架,用于绘制小鼠大脑中单神经元的全脑连接组。研究人员利用数千个重建神经元构建了两个互补的网络:基于轴突和树突重叠的“树突网”(arbor-net),以及基于预测突触位点的“终末网”(bouton-net)。通过交叉验证,这些独立导出的网络展现出强大的统计一致性,并揭示了小鼠大脑连接中固有的模块化多样性。与既有的大尺度连接组相比,所得的单神经元连接组与区域基因共表达之间显示出更紧密的相关性。此外,网络分析证实了连接组具有特定的非随机子网络模式,突显了布线图的丰富细节和结构复杂性。References: Xiong F, Liu L, Peng H.
