General Information
Term adult lateral horn AV1a1 neuron ID (Ontology) FBbt:00049331 (Fly Anatomy)
Definition Adult lateral horn output neuron of the AV1a1 group that fasciculates with the AV1 primary neurite tract (Frechter et al., 2019; Dolan et al., 2019). It is a secondary neuron that is part of the BLVp1 (VLPl&p2) lateral hemilineage (Schlegel et al., 2021). It receives input from several olfactory projection neurons in the lateral horn and has outputs in the ventral protocerebrum (Huoviala et al., 2020). It is involved in inate avoidance during egg-laying behavior (Huoviala et al., 2020). There are approximately three of these neurons per hemisphere and they are cholinergic (Dolan et al., 2019; Schlegel et al., 2021).[ FlyBase:FBrf0242477 FlyBase:FBrf0242628 FlyBase:FBrf0246460 FlyBase:FBrf0249560 ]
Also Known As "adult anterior ventral tract 1 neuron a1" ; "adult AV1a1 neuron" ; "adult LHAV1a1 neuron" (for all, see Synonyms field below)
Comment Assigned to BLVp2 (VLPl&p1) anterior hemilineage in Bates et al. (2020), updated to VLPl&p2 (BLVp1) lateral hemilineage in Schlegel et al. (2021). Cell type found in both hemibrain and FAFB (Schlegel et al., 2021).
