General Information
Term optic lobe pioneer neuron 1 ID (Ontology) FBbt:00003704 (Fly Anatomy)
Definition One of the three optic lobe pioneer neurons, which persist through development (Tix et al., 1989). In the larva, this is a cholinergic cell, with its cell body on the ventrolateral side of the optic neuropil, whose dense arbors are fully contained within the optic neuropil (Larderet et al., 2017). It is synapsed by Rh6 photoreceptor neurons and it synapses onto larval visual projection interneurons (Larderet et al., 2017).[ FlyBase:FBrf0049574 FlyBase:FBrf0084511 FlyBase:FBrf0237760 ]
Also Known As"cha-lOLP" ; "ChaLV neuron" ; "cholinergic local optic lobe pioneer cell" (for all, see Synonyms field below)
