General Information
Term protocerebral bridge 1 glomerulus-fan-shaped body-ventral gall surround neuron ID (Ontology) FBbt:00111457 (Fly Anatomy)
Definition Small field neuron of the central complex with arborization in a single glomerulus of the protocerebral bridge (PB), a column of the fan-shaped body (FB) and a region surrounding the ventral gall (Wolff et al., 2015; Hulse et al., 2021). Its FB terminals are predominantly found in layer 6, where they are mixed input and output, but arbors also extend to other layers (including layer 3) dorsally and ventrally in the same column, where they are mainly postsynaptic (Wolff et al., 2015; Hulse et al., 2021). These cells collectively target all PB glomeruli, where they have postsynaptic sites, with one cell per glomerulus (Hulse et al., 2021). It has output terminals in the ventral gall surround in one, usually contralateral, hemisphere (Wolff et al., 2015; Hulse et al., 2021). It has no phase-shift between the PB and FB (the PB glomerulus 5 cell targets the central column of the FB) (Hulse et al., 2021).[ FlyBase:FBrf0221742 FlyBase:FBrf0227801 FlyBase:FBrf0254510 ]
Also Known As "AMPG-E" ; "EB.w-AMP.d-D_GAsurround" ; "P-F-Gs" (for all, see Synonyms field below)
