NeuroMorpho.Org metadata dimensions. The annotation of neuronal reconstructions follows the ontological classification as shown here for species, brain regions, cell types and other metadata. All four dimensions are partially expanded into independent hierarchies where each concept has at least one matching instance in NeuroMorpho.Org. The red highlight exemplifies the brain region ‘fronto-insula’ being hooked to ‘humans’ in species, thereby connecting all concepts except the disjoint ones along the path. (Color figure online)
