General Information
Term adult fruitless aSP-l neuron ID (Ontology) FBbt:00110471 (Fly Anatomy)
Definition Adult fruitless neuron that develops from neuroblast SLPav2 (Ito et al., 2013; Yu et al., 2013). It has its cell body located anteroventral to the lateral horn, almost on the surface of the ventrolateral protocerebrum (Yu et al., 2010). The neurite makes a distinct turn, travels on the surface of the neuropil around the lateral horn to the posterior superior lateral protocerebrum to form broad superficial web-like arborizations in the posterior superior medial protocerebrum (PSMP) (Yu et al., 2010). It also crosses the midline and arborizes in a small region at the medial end of the contralateral PSMP (Yu et al,. 2010). There are approximately 24 of these cells per hemisphere (Cachero et al., 2010).[ FlyBase:FBrf0211884 FlyBase:FBrf0211926 FlyBase:FBrf0221412 FlyBase:FBrf0221438 ]
