General Information
Term larval pair1 neuron ID (Ontology) FBbt:00048574 (Fly Anatomy)
Definition Larval descending neuron that has its soma and ipsilateral dendrites in the subesophageal zone and a contralateral axon that projects posteriorly through the abdominal neuromeres (Carreira-Rosario et al., 2018; Tastekin et al., 2018; Lee et al., 2022). It receives stimulatory input from the mooncrawler and PDM descending neurons (Tastekin et al., 2018; Carreira-Rosario et al., 2018). It outputs onto the A27h neurons in neuromeres A5-A7 to inhibit forwards locomotion (Tastekin et al., 2018; Carreira-Rosario et al., 2018). There is one of these neurons per hemisphere and it is GABAergic (Tastekin et al., 2018).[ FlyBase:FBrf0239825 FlyBase:FBrf0240828 FlyBase:FBrf0253736 ]
Also Known As "larval SEZ descending neuron 1" ; "larval SEZ-DN1" ; "larval SEZ_DN1 neuron" (for all, see Synonyms field below)
