npo

is a Ontology.

The Neuron Phenotype Ontology (NPO) is a FAIR ontology-based data model for representing complex cellular phenotypes of neurons. It characterizes neuron types as bundles of normalized phenotypic properties across multiple dimensions including species, anatomical location, morphology, molecular constituents, electrophysiology, connectivity, and circuit roles. The NPO provides a standardized and automatable approach for naming cell types and normalizing their constituent phenotypes using identifiers from community ontologies, enabling interoperability between different neuron naming schemes and classification systems.
