General Information
Term protocerebral bridge 1 glomerulus-fan-shaped body-nodulus 2 dorsal domain neuron ID (Ontology) FBbt:00111390 (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 (FB) layers 3 and 4 and mixed terminals in the dorsal 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). This cell type is unusual among protocerebral bridge-fan-shaped body-nodulus neurons in that FB arbors of this group of neurons form an 8-column, rather than 9-column, pattern (Hulse et al., 2021). There are approximately 40 cells of this type per organism (Hulse et al., 2021). They encode ipsilateral forwards translational motion (Lu et al., 2022).[ FlyBase:FBrf0221742 FlyBase:FBrf0227801 FlyBase:FBrf0252322 FlyBase:FBrf0254510 ]
Also Known As"P-F3N2d" ; "P-FNd neuron" ; "PB-FB-NO subunit 2 dorsal domain neuron" (for all, see Synonyms field below)
CommentHulse et al. (2021) do not divide PFNd into subtypes.
