General Information
Term larval excitatory interneuron eIN-1 ID (Ontology) FBbt:00111730 (Fly Anatomy)
Definition Larval cholinergic premotor neuron that is part of lineage 18 (Zwart et al., 2016; Zarin et al., 2019). Its soma is found dorsolaterally and it extends ventrally and medially, with a couple of dorsally-extending ipsilateral branches, before crossing the midline and projecting to the contralateral dorsolateral region (Zwart et al., 2016). It outputs onto a specific subset of transverse motor neurons, including the lateral transverse muscle motor neurons and MN-DT1 (Zwart et al., 2016).[ FlyBase:FBrf0231327 FlyBase:FBrf0233076 FlyBase:FBrf0244727 ]
Also Known As "eIN-1" ; "larval A18j neuron"
