receives synaptic input in region sends synaptic output to region receives synaptic input from neuron sends synaptic output to cell optic lobe pioneer neuron optic lobe pioneer neuron 1 FBbt:00003704 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). fly_anatomy.ontology OLP1 ChaLV neuron cha-lOLP cholinergic local-OLP VFB:FBbt_00003704 1/2/3 designation appears to be arbitrary and is not used by authors - https://orcid.org/0000-0002-1373-1705. cholinergic local optic lobe pioneer cell larval visual local interneuron larval visual projection interneuron visual system neuron larval optic neuropil larval cholinergic neuron Rh6 photoreceptor of Bolwig organ
