General Information

| Term |
T5 neuron |
ID (Ontology) |
FBbt:00003736 (Fly Anatomy) |
| Definition |
T neuron with its cell body in the lobula plate cell body rind and a cell body fiber that projects through the lobula plate and via the second optic chiasma, with little or no arborization, to lobula layer 1 (Fischbach and Dittrich, 1989; Shinomiya et al., 2019). It forms a fine arborization in lobula layer 1, then its axon doubles back across the second optic chiasma to form bleb-type arborizations in a single layer of the lobula plate (Fischbach and Dittrich, 1989; Shinomiya et al., 2019). It is a cholinergic neuron (Mauss et al., 2014; Shinomiya et al., 2014). There are a large number of these cells, which are generated from neuroblasts that amplify by symmetric division (type III) before generating the T5 (and T4) neurons (Mora et al., 2018).[ FlyBase:FBrf0049410 FlyBase:FBrf0224060 FlyBase:FBrf0225094 FlyBase:FBrf0238554 FlyBase:FBrf0243899 ] |

| Comment |
Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB. The neurotransmitter was assessed with a split-GAL4 strategy using a Chat-DBD allele (FBal0198074) (Mauss et al., 2014) and single-cell transcript profiling (Shinomiya et al., 2014). Connectivity in the lobula was assessed by serial section electron microscopy of a single column (Shinomiya et al., 2014). |
