General Information
Term larval canon neuron ID (Ontology) FBbt:00048561 (Fly Anatomy)
Definition Larval abdominal neuron that is part of lineage 18. Its soma is found in a ventrolateral location and it extends an axon to the contralateral dorsal neuropil via the anterior commissure, then projects to the mesothoracic neuromere (Hiramoto et al., 2021). The ascending axon sends collaterals in each of the two to three neuromeres anterior to the cell body, with presynaptic terminals in the dorsal neuropil (Hiramoto et al., 2021). It is not a premotor neuron itself (Carreira-Rosario et al., 2018), but it outputs onto inhibitory premotor neurons (Hiramoto et al., 2021). It is cholinergic and its activity induces body wall muscle relaxation (Hiramoto et al., 2022).[ FlyBase:FBrf0238464 FlyBase:FBrf0249023 ]
Also Known As "larval A18g neuron"
