General Information
Term adult lateral horn AV4a1 neuron ID (Ontology) FBbt:00049345 (Fly Anatomy)
Definition Adult lateral horn local neuron of the AV4a1 group that fasciculates with the AV4 primary neurite tract (Frechter et al., 2019; Dolan et al., 2019). There are approximately six of these neurons per hemisphere and they are GABAergic (Dolan et al., 2019; Schlegel et al., 2021). They are secondary neurons, most belong to the BLD4 (LHl1) lateral hemilineage, but around one per hemisphere belongs to the LHl4 (BLD1) anterior hemilineage (Bates et al., 2020).[ FlyBase:FBrf0242477 FlyBase:FBrf0242628 FlyBase:FBrf0246460 FlyBase:FBrf0249560 ]
Also Known As "adult anterior ventral tract 4 neuron a1" ; "adult AV4a1 neuron" ; "adult LHAV4a1 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.
