General Information
Term larval DN1 neuron ID (Ontology) FBbt:00001915 (Fly Anatomy)
Definition A neuron whose soma is located in the dorso-anterior region of the larval brain cortex and projects to the larval optic neuropil (Keene et al., 2011). Some of the processes run along the axons of the larval s-LNv neurons and arborize near the s-LNv dendrites. It exhibits strong circadian cycling of Period (FBgn0003068) expression starting at about 15 hours post-hatching. There are one or two of these cells per hemisphere.[ FlyBase:FBrf0098279 FlyBase:FBrf0213587 ]
Also Known As"DN1L" ; "dorsal neuron-1 larval" ; "larval dorsal neuron-1"
CommentExpression of Period was determined by per-lacZ fusion expression (Kaneko et al., 1997).
