General Information
Term larval A27h neuron ID (Ontology) FBbt:00111668 (Fly Anatomy)
Definition Cholinergic premotor neuron of the larval abdominal neuromere that is part of lineage 27 (Fushiki et al., 2016). Its primary neurite extends anteriorly, with the most anterior branch crossing the midline and it outputs to the A27e neuron and ipsi- and contralateral A1-7 DA1 motor neuron (Fushiki et al., 2016).[ FlyBase:FBrf0231328 FlyBase:FBrf0231611 ]
Comment These neurons were identified in a EM reconstruction of a volume that includes the posterior half of abdominal segment 2 and abdominal segment 3, of a 12-24h old first instar larva. 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): to A27e (15), A1-7 DA1 motor neuron (10/10) (Schneider-Mizell et al., 2016).
