General Information
Term proximal medullary amacrine neuron Pm7 ID (Ontology) FBbt:20007265 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260545 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "adult CB3850 neuron" ; "CB3850" ; "Pm11" (for all, see Synonyms field below)
Comment 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).
