General Information
Term adult lateral horn AV4a4 neuron ID (Ontology) FBbt:00049348 (Fly Anatomy)
Definition Adult lateral horn local neuron of the AV4a4 group that fasciculates with the AV4 primary neurite tract (Dolan et al., 2019). It is a secondary neuron that is part of the BLD4 (LHl1) lateral hemilineage (Bates et al., 2020). There are approximately 6-8 of these cells per hemisphere and they are GABAergic (Dolan et al., 2019; Schlegel et al., 2021).[ FlyBase:FBrf0242477 FlyBase:FBrf0246460 FlyBase:FBrf0249560 ]
Also Known As "adult anterior ventral tract 4 neuron a4" ; "adult AV4a4 neuron" ; "adult LHAV4a4 neuron" (for all, see Synonyms field below)
Comment Cell type found in both hemibrain and FAFB (Schlegel et al., 2021). Bates et al. (2020) classify this as an output neuron, but Schlegel et al. (2021) call this a local neuron.
