(2024), based on FlyWire v783 (FAFB) data (Dorkenwald et al., 2024; Schlegel et al., 2024), identified at light level by Nern et al. (2025). fly_anatomy.ontology Pm11 FBbt:20007265 adult CB3850 neuron Pm7 Adult proximal medullary amacrine neuron with its soma in the optic lobe (Nern et al., 2025). It has its pre- and post-synapses in medulla layers M9-M10, spanning around 100 columns (Nern et al., 2025). Its predicted neurotransmitter is GABA (Eckstein et al., 2024; Nern et al., 2025). There are approximately 15 of these cells per hemisphere (Nern et al., 2025). CB3850
