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 M8 in around 15-20 columns (Nern et al., 2025). It also has pre- and post-synapses in the lobula, in a few columns of layer 6 (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 45 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). fly_anatomy.ontology MeLo7 FBbt:00053507 VFB:FBbt_00053507 MeLo7 adult cholinergic neuron unilateral
