ExR [FBbt_00003654]

Ring neuron with extensive arborizations outside of the ellipsoid body (Hanesch et al., 1989; Omoto et al., 2018). Unlike the R-neurons, these neurons do not develop from neuroblast DALv2 (Omoto et al., 2018), and some of these cells are derived from each of BAmv1, DM6, DM4, and DM3 (Kandimalla et al., 2023). There are usually only one or two of each type of extrinsic ring neuron per hemisphere (Hulse et al., 2021).
