General Information
Term optic lobe pioneer neuron 2 ID (Ontology) FBbt:00003705 (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 glutamatergic cell, with its cell body on the ventrolateral side of the optic lobe, whose dense arbors are fully contained within the optic lobe (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:FBrf0204872 FlyBase:FBrf0237760 ]
Also Known As"glu-lOLP" ; "GluLV neuron" ; "glutamatergic local optic lobe pioneer cell" (for all, see Synonyms field below)
Comment1/2/3 designation appears to be arbitrary and is not used by authors - https://orcid.org/0000-0002-1373-1705). There are sometimes two of these cells in one hemisphere (Larderet et al., 2017.
