General Information
Term lobe system of mushroom body ID (Ontology) FBbt:00003688 (Fly Anatomy)
Definition The mushroom body lobe system consists of a vertical (dorsal) branch and a medial branch. In the larva, there are only two lobes (one dorsal, one medial), but remodeling during the pupal stage results in five lobes (two dorsal, three medial) in the adult (Lee et al., 1999).[ FlyBase:FBrf0105215 FlyBase:FBrf0111409 FlyBase:FBrf0144836 ]
