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.
