| Term |
T2a neuron |
ID (Ontology) |
FBbt:00003729 (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, bifurcating in medulla layer M5 and forming fine arbors throughout layers M1-4. 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.[ FlyBase:FBrf0049410 FlyBase:FBrf0222324 FlyBase:FBrf0243899 ] |
