Metadata complexity. a Temporal trend in the counts of metadata terms used in NeuroMorpho.Org to annotate the animal species (including strains), brain regions, and cell types. Each data point marks a version release. b Word clouds of the most common terms in the database across the main categories (from left to right) of animal species/strains, brain regions, and cell types. Word size corresponds to relative usage frequency
