General Information
Term larval supraesophageal zone ID (Ontology) FBbt:00051070 (Fly Anatomy)
Definition Neuropil mass above the larval esophagus consisting of the protocerebral and deutocerebral neuromeres and part of the tritocerebrum.[ FlyBase:FBrf0224194 ]
Also Known As "larval SPZ"
Comment This is analogous to the adult term based on Ito et al. (2014), reflecting location relative to the esophagus, rather than segmental identity.
