General Information
Term adult s-LNv neuron ID (Ontology) FBbt:00007428 (Fly Anatomy)
Definition Neuron of the period-expressing LNv cluster of the adult brain, with a small cell body and generally located more ventrally than the l-LNv neurons (Helfrich-Forster et al., 2007). There are 5 cells present in each cluster, all except one of which express Pdf (Helfrich-Forster et al., 2007; Ma et al., 2021). These cells also express sNPF (Johard et al., 2009; Ma et al., 2021).[ FlyBase:FBrf0193849 FlyBase:FBrf0208477 FlyBase:FBrf0247880 ]
Also Known As "adult sLNv" ; "adult small LNv" ; "s-LNv" (for all, see Synonyms field below)
