Interface of Brain Explorer software for viewing brain anatomy and gene expression data in 3D. The main window of the Brain Explorer application displays Rab37 expression in a coronal slice from the adult mouse brain, in which gene expression is indicated by colored spheres. The location of the thalamic structure ventral anterior-lateral complex is shown in muted pink. The structural ontology panel on the right-hand side shows the color-coded hierarchy, which can be switched between hierarchical and alphabetical mode. Bookmarks portray saved default and custom views. At the bottom right-hand side of the window is the list of genes shown in the 3D view.
