General Information
Term adult ellipsoid body-protocerebral bridge 1 glomerulus-dorsal/ventral gall neuron ID (Ontology) FBbt:00047030 (Fly Anatomy)
Definition Small field neuron of the central complex with dendritic and axonal arbors in the inner, outer and posterior layers of either a half or a full ellipsoid body (EB) slice (wedge), and axon terminals in the dorsal or ventral gall and a single protocerebral bridge glomerulus (excluding glomerulus 9) (Lin et al., 2013; Wolff et al., 2015). Neurons that target odd or even numbered protocerebral bridge glomeruli target the dorsal or ventral gall, respectively (Lin et al., 2013; Wolff et al., 2015). These neurons receive inhibitory input from delta 7 (PB 18 glomeruli) neurons and they are cholinergic (Turner-Evans et al., 2020). These cells output to P-EN1 neurons and P-EG neurons of the same glomerulus in the protocerebral bridge, and form less specific 'hyper-local' feedback loops with P-EN1 neurons in the EB (Turner-Evans et al., 2020). It also receives input from R4d ring neurons and P-EN2 neurons in the EB (Turner-Evans et al., 2020).[ FlyBase:FBrf0221742 FlyBase:FBrf0227801 FlyBase:FBrf0240744 FlyBase:FBrf0246945 ]
Also Known As "E-PG neuron" ; "EB-IDFP D/VSB-PB 1 glomerulus neuron" ; "EB-PB 1 glomerulus-D/Vgall neuron" (for all, see Synonyms field below)
Comment Based on images/diagrams in Lin et al. (2013), Wolff et al. (2015) and Turner-Evans et al. (2020), these appear to innervate the ipsilateral PB and contralateral gall, but could not find confirmation of this - https://orcid.org/0000-0002-1373-1705.
