Interneuron that has dendrites in a single protocerebral bridge (PB) glomerulus, and axon terminals in one tile domain of the ellipsoid body (EB) and either the dorsal or ventral gall (Wolff et al., 2015). PB arbors may spill into neighboring glomeruli (Wolff and Rubin, 2018) and EB terminals may spread slightly into neighboring tiles (Wolff et al., 2015). Neurons that target odd or even numbered PB slices target the dorsal or ventral gall, respectively, with arbors filling the region (Wolff et al., 2015). These neurons are cholinergic (Turner-Evans et al., 2020). They are synapsed by E-PG neurons of the same PB glomerulus and output onto P-EN2 neurons in the EB (Turner-Evans et al., 2020). Its soma is located close to the PB glomerulus it innervates (Wolff et al., 2015). Collectively, all 9 protocerebral bridge glomeruli are targeted by cells of this type (Wolff and Rubin, 2018). It develops from one of the four central complex neuroblasts (Sullivan et al., 2019).

Thought not to arborize in PB G9 by Wolff et al. (2015), this was amended in Wolff and Rubin (2018) and they changed the name from PBG1-8.s-EBt.b-D/V GA.b to PBG1-9.s-EBt.b-D/V GA.b. This neuron was not identified by Lin et al. (2013) (FBrf0221742) and does not correspond to PB1-glomerulus->EBC-IDFPDBSB or any other Lin et al. (2013) type (Wolff and Rubin, 2018).
