Term adult fruitless aSP3 neuron ID (Ontology) FBbt:00110553 (Fly Anatomy)
Definition Adult fruitless neuron with its soma in the anterior superior protocerebrum, in a cleft between the anterior optic tubercle and the mushroom body lobe junction, and a descending projection that innervates all three thoracic neuromeres (Yu et al., 2010).[ FlyBase:FBrf0211884 ]
Also Known As"fru-aSP3"
CommentProbably a subtype of aSP3 in Lee et al. (2000) - FBrf0128543, since Yu et al. (2010) map this and other clusters to aSP3. Yu et al. (2010) map this to Kimura et al. (2008) AL4, but Cachero et al. (2010) map AL4 to aSP-d.
