General Information
Term adult antennal lobe local neuron TC-LN ID (Ontology) FBbt:20003767 (Fly Anatomy)
Definition Adult local neuron of the antennal lobe that develops from neuroblast ALv2 (Schlegel et al., 2021) and has its soma ventral to the antennal lobe (Chou et al., 2022). It is unilateral and it has a sparse arborization pattern (Schlegel et al., 2021). It innervates antennal lobe glomeruli DA1, DC3, DL3, DL4, VA1d and VA1v (Chou et al., 2022). Other glomeruli innervated can vary between individuals or within the same individual under different conditions (Chou et al., 2022). Its presynapses are evenly distributed along its processes (Chou et al., 2022). It receives input mainly from olfactory receptor neurons and sends output to uniglomerular projection neurons, but its connectivity pattern can vary in each glomerulus (Chou et al., 2022). There is one of these cells per hemisphere (Chou et al., 2022). It is glutamatergic (Chou et al., 2022).[ FlyBase:FBrf0246888 FlyBase:FBrf0249560 FlyBase:FBrf0258592 ]
Also Known As "adult antennal lobe local neuron type 36 of neuroblast ALv2" ; "adult antennal lobe local neuron v2LN36" ; "adult antennal lobe trichoid local neuron" (for all, see Synonyms field below)
Comment Chou et al. (2022) say name is due to innervation of glomeruli targeted by trichoid ORNs (DA1, DL3, Va1d, Va1v), but are not explicit about what 'TC-LN' stands for.
