General Information
Term proximal medullary amacrine neuron Pm11 ID (Ontology) FBbt:20007242 (Fly Anatomy)
Definition Adult proximal medulla amacrine neuron with its soma ventral-medial to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). It enters the proximal medulla has pre- and post-synapses in layers M9-M10 in over 500 columns, as well as some fibers that extend to layer M8 (Nern et al., 2025). Its predicted neurotransmitter is GABA (Eckstein et al., 2024; Nern et al., 2025). There are approximately two of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260545 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "adult CB3827 neuron" ; "CB3827" ; "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). Soma location is based on the closest annotated neuropil region in FlyWire.
