| Term |
abdominal dorsal multidendritic neuron ddaD |
ID (Ontology) |
FBbt:00002410 (Fly Anatomy) |
| Definition |
Larval ddaD neuron with its soma in an abdominal segment. It develops from a common precursor with the abdominal desC neuron (Veling et al., 2019). It has strong outputs to the Jaam2 and Jaam3 neurons (Heckscher et al., 2015), as well as A27j and A02b (Schneider-Mizell et al., 2016). It is remodeled into the adult ddaD neuron during metamorphosis (Shimono et al., 2009).[ FlyBase:FBrf0080250 FlyBase:FBrf0209127 FlyBase:FBrf0229965 FlyBase:FBrf0231328 FlyBase:FBrf0244192 ] |
| Comment |
These neurons were identified in two EM reconstructions: one of the full CNS of a 6h old first instar larva, and another of abdominal segment 3 of a 12-24h old first instar larva (Heckscher et al., 2015; Schneider-Mizell et al., 2016). For Heckscher et al. (2015) only bilateral connections are reported. The number of identified output synapses in A1 was the following (number in brackets left/right): to Jaam2 (34/25), Jaam3 (35/40). It is still not known if the pattern of connections with Jaam neurons in A1 is replicated in the other abdominal segments (Heckscher et al., 2015). For Schneider-Mizell et al. (2016), the number of connections was estimated from the publication figures. The number of output synapses was the following (number in brackets left/right where available; ipsi- and contralateral connections separated by comma): to A27j (21), A02b (10, 14/15, 15) (Schneider-Mizell et al., 2016). |
