ER2 [FBbt_00003651]
ER2
ID: FBbt_00003651
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. (Renn et al., 1999, Young and Armstrong, 2010, Hanesch et al., 1989, Omoto et al., 2018, Lin et al., 2013)
