General Information
Term adult intrinsic protocerebral bridge 18 glomeruli-2 glomeruli neuron ID (Ontology) FBbt:00111057 (Fly Anatomy)
Definition Large field neuron of the central complex that is intrinsic to the protocerebral bridge (Lin et al., 2013; Wolff et al., 2015). It has dendritic arbors in 18 glomeruli, and axon terminals distributed in two glomeruli spaced seven glomeruli apart (Wolff et al., 2015). There are three subtypes that differ on the location of the axon terminals (Lin et al., 2013). One subtype has terminals in the ipsilateral glomerulus 7 and contralateral glomerulus 2; another with terminals in the ipsilateral glomerulus 6 and contralateral glomerulus 3; and the last with terminals in the ipsilateral glomerulus 5 and contralateral glomerulus 4 (Lin et al., 2013; Wolff et al., 2015).[ FlyBase:FBrf0221742 FlyBase:FBrf0227801 FlyBase:FBrf0246945 ]
Also Known As"Delta7 neuron" ; "PB15-glomeruli neuron" ; "PB18.sGxdelta7Gy.b neuron" (for all, see Synonyms field below)
CommentDiscrepancy between Lin et al. (2013) and Wolff et al. (2015) due to discovery of additional medial PB glomerulus in either hemisphere.
