Figure 3: Classification using registered arbor densities reveals the matching between genetic and structural cell types.
From: A genetic and computational approach to structurally classify neuronal types

(a) Hierarchical clustering of all the cells in the data set. Individual clusters were rotated for a vertical display and scaled up 7.5 times to reveal the details. Each leaf corresponds to a cell. Cells (leaves) from known genetic strains are labelled while unlabelled leaves correspond to at-large cells. (bottom) Each structural cluster is assigned a capital letter. Arrows indicate putative new cell types. (b) Matrix illustrating the consistent sorting of genetically defined cells into structural clusters. Only nonzero entries are shown.
