General Information
Term larval s-LNv neuron ID (Ontology) FBbt:00100177 (Fly Anatomy)
Definition Larval neuron of the period-expressing LNv cluster, with a small cell body. These neurons innervate the larval optic neuropil (Larderet et al., 2017) and are thought to develop into the adult s-LNv neurons (Kaneko et al., 1997). There are 5 cells present in each cluster, all except one of which express Pdf (FBgn0023178).[ FlyBase:FBrf0098279 FlyBase:FBrf0213587 FlyBase:FBrf0237760 ]
Also Known As "larval clock LaN" ; "larval LNv neuron"
Comment This appears to be the only type of lateral period neuron in the larva (Kaneko et al., 1997), so this term may be equivalent to FBbt:00001913 'larval LN period neuron' - https://orcid.org/0000-0002-1373-1705.
