General Information
Term descending neuron of the anterior dorsal brain DNa12 (male) ID (Ontology) FBbt:00051201 (Fly Anatomy)
Definition Adult aSP22 descending neuron of the male (McKellar et al., 2019). It is similar to the female neuron, with more dense arborization in some areas of the brain, but lacking a branch on the dorsal part of the neuron (McKellar et al., 2019). It is involved in male courtship behavior for the engagement of the female - proboscis extension, followed by abdominal bending, then foreleg lifting (McKellar et al., 2019). Activation also causes simultaneous movement of all legs prior to the engagement sequence (McKellar et al., 2019). It expresses the male isoform of fruitless (McKellar et al., 2019).[ FlyBase:FBrf0241391 ]
