General Information

Term

adult lateral horn AV7a1 neuron

ID (Ontology)

FBbt:00049367 (Fly Anatomy)

Definition

Adult lateral horn output neuron of the AV7a1 group that fasciculates with the AV7 primary neurite tract (Frechter et al., 2019; Dolan et al., 2019). It is a secondary neuron that develops from the DAL1l (AOTUv2) neuroblast (Bates et al., 2020). They are cholinergic and glutamatergic (Dolan et al., 2019).[ FlyBase:FBrf0242477 FlyBase:FBrf0242628 FlyBase:FBrf0246460 FlyBase:FBrf0249560 ]

Also Known As

"adult anterior ventral tract 7 neuron a1" ; "adult AV7a1 neuron" ; "adult LHAV7a1 neuron" (for all, see Synonyms field below)

Comment

Glutamate and acetylcholine determined by antibody staining (Dolan et al., 2019). Schlegel et al. (2021) predict GABA based on hemilineage.
