General Information
Term adult ellipsoid body extrinsic ring neuron ExR4 ID (Ontology) FBbt:00047036 (Fly Anatomy)
Definition Extrinsic ring neuron that develops from the BAmv1 (LALv1) neuroblast and has its cell body in a cluster in the anterior brain cortex, ventral to the antennal lobe (Omoto et al., 2018). It follows the longitudinal ventromedial fascicle, then has dense branches, restricted to the gall and part of the anterior lateral accessory lobe surrounding the gall, containing mainly postsynaptic sites (Omoto et al., 2018; Hulse et al., 2021). It also has mixed terminals in the outer posterior domain of the ellipsoid body (Omoto et al., 2018; Hulse et al., 2021). There is one of these cells per hemisphere and it develops from neuroblast BAmv1 (Kandimalla et al., 2023).[ FlyBase:FBrf0240929 FlyBase:FBrf0254510 FlyBase:FBrf0257023 ]
