ID: FBbt_20007680

Adult unilateral visual centrifugal neuron with its soma anterior to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). In the central brain, it receives input in the posterior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). In the optic lobe, it has postsynapses in lobula layer 6, across around 30 columns, and pre- and post-synapses in medulla layer M6 across around 100 columns (Nern et al., 2025). Distinct branches innervate each optic neuropil region without passing through the optic chiasm (Nern et al., 2025). Its predicted neurotransmitter is glutamate (Eckstein et al., 2024; Nern et al., 2025). There are approximately 2 of these cells per hemisphere (Nern et al., 2025).

Cell type from Schlegel et al. (2024), based on FlyWire v783 (FAFB) data (Dorkenwald et al., 2024; Schlegel et al., 2024), identified at light level by Nern et al. (2025). Soma location is based on the closest annotated neuropil region in FlyWire.
