3D human pyramidal dendrites with spines

R workspace with the five human pyramidal neurons used in the paper "Three-dimensional spatial modeling of spines along dendritic networks in human cortical pyramidal neurons". The workspace contains two hyperframes called apical and basal with the apical and basal dendrites of the analyzed cells, respectively, in the same order in which they appear in the paper. Use spatstat package for a proper visualization of the data. Each hyperframe consists in three columns: vertices: three-dimensional point pattern specifying the vertices of the dendritic network. m: adjacency matrix of logical values equal to TRUE when the corresponding vertices are joined by a line. X: three-dimensional point pattern specifying the locations of the spines in the network.

本R工作区包含论文《人类皮层锥体神经元树突网络棘突的三维空间建模》中使用的5个人类锥体神经元。该工作区包含两个分别名为apical和basal的超帧（hyperframe），二者依次存储所分析细胞的顶树突与基树突，且排列顺序与论文中一致。请使用spatstat包对该数据进行规范可视化。每个超帧均包含三列：vertices（顶点）：用于指定树突网络顶点的三维点模式；m：逻辑值邻接矩阵，当对应顶点以线段相连时其取值为TRUE；X：用于指定该网络中树突棘位置的三维点模式。
