ER4d [FBbt_00007538]

Ring neuron R4 whose arborization in the ellipsoid body is largely restricted to the outermost part of the ellipsoid body outer central domain (Renn et al., 1999; Omoto et al., 2018. It has glomerular dendrites restricted to the lateral part of the superior bulb (Omoto et al., 2018. In the ellipsoid body, it synapses to E-PG neurons, as well as forming inhibitory connections with other R4d neurons (Turner-Evans et al., 2020. It is GABAergic (Turner-Evans et al., 2020. (Renn et al., 1999, Turner-Evans et al., 2020, Young and Armstrong, 2010, Omoto et al., 2018)
