Examples of two different simulated 3D neuronal populations and their Voronoi domain volumes. a: 3D distributions of simulated populations of cells based on a minimal distance spacing rule (left) and on a jittered hexagonal lattice (right), with the Voronoi domain of a single cell illustrated within each field. The data summary panel to the right of each 3D distribution provides statistical details associated with the illustrated cell. b: Frequency distributions of Voronoi domain volumes associated with every cell (excluding those at the border) in the fields illustrated in a. The 3D depictions to the right of each frequency distribution portray the variation in Voronoi domain volume within space, where both color and increasing size signify an increase in volume. The histograms convey the population variability, while the bubble diagrams display that variability within 3D space.
