General Information
Term adult medulla visual projection neuron MeVPLp1 ID (Ontology) FBbt:20007600 (Fly Anatomy)
Definition Adult visual projection neuron with its soma ventral 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 optic lobe, it receives input in the ipsilateral medulla layer M4, in around 500 columns, and it sends output to approximately 50 columns of layer 4 of the contralateral lobula plate (Nern et al., 2025). It also has a smaller number of presynapses in the ipsilateral lobula plate layer 4 (Schlegel et al., 2024; Dorkenwald et al., 2024; Nern et al., 2025) In the central brain, it has presynapses in the inferior posterior slope, wedge, saddle and gnathal ganglion in both hemispheres (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There is one of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "adult MeLp1 neuron" ; "LPT56" ; "MeLp1" (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.
