Adult unilateral optic-lobe-intrinsic neuron with its soma on the ventral side of the lobula (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, primarily in medulla layer M6 in around 15 columns (Nern et al., 2025). It also has pre- and post-synapses in the lobula, in a few columns of layers 5B-6 (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 30 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).
