General Information
Term adult fruitless aSP-a (male) neuron ID (Ontology) FBbt:00110595 (Fly Anatomy)
Definition Adult male fruitless-expressing neuron that develops from the SMPad1 neuroblast (Ito et al., 2013; Yu et al., 2013). It has its soma in the pars intercerebralis and projects laterally, arborizing extensively in the lateral protocerebral complex (Yu et al., 2010). Many of these cells are activated by the presence of females, but not males (Takayanagi-Kiya and Kiya, 2019). There are approximately 50-60 of these cells per hemisphere (Lee et al., 2000; Cachero et al., 2010).[ FlyBase:FBrf0128543 FlyBase:FBrf0205974 FlyBase:FBrf0211884 FlyBase:FBrf0211926 FlyBase:FBrf0221412 FlyBase:FBrf0221438 FlyBase:FBrf0241873 ]
