(2025). Grouped as aMe17a in hemibrain (Nern et al., 2025). aMe17a2 Adult unilateral visual centrifugal neuron that receives input mainly in the posterior lateral protocerebrum, but also in lobula layer 6, medulla layer M6, the accessory medulla and the superior posterior slope (Dorkenwald et al., 2024; Schlegel et al., 2024; Nern et al., 2025). It sends output to around 150 columns of medulla layers M6-M7, where it has a large tangential arbor, with additional output in M1 and M2-M3 (Dorkenwald et al., 2024; Schlegel et al., 2024; Nern et al., 2025). It is predicted to be glutamatergic (Eckstein et al., 2024; Nern et al., 2025). There is one of these cells per hemisphere (Nern et al., 2025).
