General Information
Term adult ellipsoid body ring neuron R2 ID (Ontology) FBbt:00003651 (Fly Anatomy)
Definition R-neuron that enters the ellipsoid body from the central canal, projects centrifugally, and has axon terminals throughout the outer central domain of the ellipsoid body (Hanesch et al., 1989; Young and Armstrong, 2010; Omoto et al., 2018). It does not arborize in a narrow region on the outermost periphery of this domain, which is where R4d terminals are found (Omoto et al., 2018). Proximal dendrites of R2 form club-shaped glomerular endings in the medial two-thirds of the superior bulb (Omoto et al., 2018).[ FlyBase:FBrf0049409 FlyBase:FBrf0111476 FlyBase:FBrf0210156 FlyBase:FBrf0221742 FlyBase:FBrf0240929 ]
