General Information
Term larval A18b neuron ID (Ontology) FBbt:00048579 (Fly Anatomy)
Definition Cholinergic premotor neuron of the larval abdominal neuromere that is part of lineage 18 (Carreira-Rosario et al., 2018). A18b neurons activate sequentially (anterior to posterior) during backwards locomotion (Carreira-Rosario et al., 2018). The A1 neuron, but not those in other neuromeres, receives input from a mooncrawler descending neuron (Carreira-Rosario et al., 2018).[ FlyBase:FBrf0238464 ]
