| Term |
T2 neuron |
ID (Ontology) |
FBbt:00003728 (Fly Anatomy) |
| Definition |
T neuron with its soma posteriorly adjacent to the gap between the medulla and lobula plate and a cell body fiber that projects along the proximal surface of the medulla before branching in the second optic chiasm (Fischbach and Dittrich, 1989; Shinomiya et al., 2019). One branch projects into a medulla column, where it forms a bushy, fine, arborization in medulla layer M9 and then projects through the rest of the medulla column, forming fine arborizations in M1, M2 and M5. The other branch forms a terminal arborization in lobula layer 3 that is much wider than a single column and has bleb-type terminal branches. It seems to be capable of cholinergic and GABAergic neurotransmission.[ FlyBase:FBrf0049410 FlyBase:FBrf0212356 FlyBase:FBrf0220286 FlyBase:FBrf0222324 FlyBase:FBrf0243899 ] |

| Comment |
The acetylcholine neurotransmitter was assessed by co-labelling cells with a Cha-GAL4.7.4 driver (FBtp0014830) and an anti-ChAT antibody (Varija Raghu et al., 2011). The GABA neurotransmitter was assessed by the intersection of the expression of the VGAT-GAL4 driver (FBtp0069181) and an antibody against GABA (Raghu et al., 2013). Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB. |
