General Information
Term protocerebral bridge 1 glomerulus-fan-shaped body-nodulus 3 medial domain neuron ID (Ontology) FBbt:00111513 (Fly Anatomy)
Definition Small field neuron of the central complex with dendritic arbors in a single glomerulus of the protocerebral bridge, presynaptic terminals in a tooth of fan-shaped body layer 1 and mixed terminals in the medial domain of contralateral nodulus 3 (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).[ FlyBase:FBrf0227801 FlyBase:FBrf0254510 ]
Also Known As"P-FNm neuron" ; "PB-FB-NO subunit 3 medial domain neuron" ; "PB-FB-NO3 medial domain neuron" (for all, see Synonyms field below)
CommentHulse et al. (2021) divide PFNm into two (a and b) subtypes, but it is not clear how these are different from each other or which cells correspond to the type in Wolff et al. (2015).
