Thought to correspond to PBG1-8.s-EBt.b-D/V GA.b (renamed to PBG1-9.s-EBt.b-D/V GA.b) by Wolff et al. (2015), this was amended in Wolff and Rubin (2018) and it is now thought to correspond to PBG1-9.s-EBc.b-D/V GA.b. Not identified in hemibrain dataset (Hulse et al., 2021 - FBrf0254510). PEIR PB1-glomerulus>EBC-IDFPR-DSB Interneuron that receives input in a glomerulus of the protocerebral bridge (PB), and has outputs in the ellipsoid body (EB), where its arbor enwraps the canal (central hole) and the dorsal or ventral gall (Lin et al., 2013; Wolff and Rubin, 2018). Its PB arbor often spills into neighboring glomeruli (Wolff and Rubin, 2018). The mapping between PB glomeruli and EB tiles is the same as for the 'tile' cell, but EB arbors extend deeper into the medial, and sometimes anterior, shells (Wolff and Rubin, 2018). Neurons that arborize an odd-numbered protocerebral bridge glomerulus project to the dorsal gall, whereas even-numbered ones project to the ventral gall, with sparse arborization, close to the surface of the region (Wolff and Rubin, 2018). Collectively, all 9 protocerebral bridge glomeruli are targeted by cells of this type (Wolff and Rubin, 2018).
