General Information
Term adult fruitless aSP-b (male) neuron ID (Ontology) FBbt:00110597 (Fly Anatomy)
Definition Adult male fruitless neuron that develops from neuroblast SMPad2 (Ito et al., 2013; Yu et al., 2013). There are approximately 15 of these cells per hemisphere, with their somas in the pars intercerebralis (Lee et al., 2000; Cachero et al., 2010).[ FlyBase:FBrf0128543 FlyBase:FBrf0205974 FlyBase:FBrf0211926 FlyBase:FBrf0221412 FlyBase:FBrf0221438 ]
Also Known As"adult male fruitless aSP1 neuron" ; "male aSP-b neuron" ; "male fru-aSP1 neuron"
CommentCorrespondence of Yu et al. (2010) - FBrf0211884 aSP1 to aSP1 in other studies is unclear - they also seem to call this aSP2-p in fig S2 and give contradictory correspondences in table S1. and Cachero et al. (2010) list Yu et al. (2010) aSP1 as possibly corresponding to aSP-b and aSP-c.
