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). glu-lOLP 1/2/3 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.
