General Information
Term larval s-LNv Pdf neuron ID (Ontology) FBbt:00100167 (Fly Anatomy)
Definition Larval s-LNv neuron that expresses Pdf (FBgn0023178) from 4-5 hours after hatching and persists into adulthood (Helfrich-Forster, 1997). Its cell body is located close to the larval optic neuropil, into which dendritic fibers extend, spanning the distal and intermediate regions (Larderet et al., 2017). It projects to the superior lateral protocerebrum, where it has presynaptic terminals (Larderet et al., 2017). There are four of these cells per hemisphere.[ FlyBase:FBrf0093121 FlyBase:FBrf0237760 ]
Also Known As"larval Pdf-LaN" ; "larval small pigment dispersing factor neurons at the medulla" ; "larval sPDFMe" (for all, see Synonyms field below)
