ER1 [FBbt_00003650]

R-neuron that passes through the ellipsoid body canal, entering the neuropil from the posterior part of the canal and projecting outwards and slightly anteriorly (Omoto et al., 2018). Its terminals define the boundary between the inner and outer posterior layers of the ellipsoid body (Omoto et al., 2018). Unlike most other R-neurons, its dendritic branches are found on the lateral surface of the lateral accessory lobe, rather than the bulb (Omoto et al., 2018).

Adult GABAergic lineage EBa1 DALv2 secondary neuron

R-neuron that passes through the ellipsoid body canal, entering the neuropil from the posterior part of the canal and projecting outwards and slightly anteriorly (Omoto et al., 2018). Its terminals define the boundary between the inner and outer posterior layers of the ellipsoid body (Omoto et al., 2018). Unlike most other R-neurons, its dendritic branches are found on the lateral surface of the lateral accessory lobe, rather than the bulb (Omoto et al., 2018).

This R1 neuron, identified by Renn et al, (1999), is now thought to be distinct from the R1 neuron identified by Hanesch et al. (1989), which is most likely one of the R3 neurons (Omoto et al., 2018). Ofstad et al. (2011) use two drivers stated to target R1 neurons, both of which were shown to target subclasses of R3, and not R1, by Omoto et al. (2018).
