General Information
Term protocerebral bridge 1 glomerulus-fan-shaped body-nodulus 2 ventral domain neuron ID (Ontology) FBbt:00111512 (Fly Anatomy)
Definition Small field neuron of the central complex with dendritic arbors in a single glomerulus of the protocerebral bridge, presynaptic terminals in fan-shaped body layer 3 and mixed terminals in the ventral domain of contralateral nodulus 2 (Wolff et al., 2015; Hulse et al., 2021). These cells collectively target protocerebral bridge glomeruli 2-9 (Wolff et al., 2015; Hulse et al., 2021). There are approximately 20 cells of this type per organism (Hulse et al., 2021). They encode contralateral backwards translational motion (Lu et al., 2022).[ FlyBase:FBrf0227801 FlyBase:FBrf0252322 FlyBase:FBrf0254510 ]
Also Known As"P-F3N2v" ; "PB-FB-NO subunit 2 ventral domain neuron" ; "PB-FB-NO2 ventral domain neuron" (for all, see Synonyms field below)
CommentHulse et al. (2021) do not divide PFNv into subtypes.
