General Information
Term adult asymmetrical body-fan-shaped body layer 8 neuron ID (Ontology) FBbt:00049144 (Fly Anatomy)
Definition Adult neuron that has columnar projections in the fan-shaped body (FB), arborizing in layer 8, and has mixed presynaptic and postsynaptic terminals in the asymmetrical body (AB) (Wolff and Rubin, 2018). Some of these neurons also have terminals in layer 1 of the FB (Wolff and Rubin, 2018; Hulse et al., 2021). Most of these follow a single column, but some extend through both lateralmost columns (Wolff and Rubin, 2018; Hulse et al., 2021). There are approximately 54 of these cells per fan-shaped body, defining approximately nine columns (Hulse et al., 2021). Neurons that innervate a left side column of the FB target the left AB and neurons that innervate right or central FB columns target the right AB (Hulse et al., 2021).[ FlyBase:FBrf0240744 FlyBase:FBrf0254510 ]
Also Known As"AB-FBl8 neuron" ; "AB.s.b-FBl8.b neuron" ; "adult A-F neuron" (for all, see Synonyms field below)
