Adult unilateral optic-lobe-intrinsic neuron with its soma on the dorsal side of the medulla (Dorkenwald et al., 2024; Schlegel et al., 2024; Nern et al., 2025). It bifurcates near the soma, sending one branch to the medulla and one to the lobula, without passing through the optic chiasm (Nern et al., 2025). It receives input, but also has presynapses, in medulla layers M3-M4 and M6-M7 in around 10 columns (Nern et al., 2025). It also has pre- and post-synapses in the lobula, in around 10 columns of layer 6 (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 40 of these cells per hemisphere (Nern et al., 2025).

Cell type identified in two sets of EM data (Matsliah et al., 2024; Nern et al., 2024), matched and identified at light level by Nern et al. (2025).
