(2018) say this may previously have been grouped in with R2 or R4 neurons in studies using less specific drivers, but maintain that it is a distinct class due to its centripetal projection pattern. R-neuron whose axons specifically target the small, anterior domain of the ellipsoid body, projecting short terminal branches centripetally (Omoto et al., 2017; Omoto et al., 2018). Dendritic terminals are confined to a small distinct ventromedial locus in the superior bulb (Omoto et al., 2018). ER5 superior bulb
