General Information
Term medulla columnar neuron MC64 ID (Ontology) FBbt:00051218 (Fly Anatomy)
Definition Medulla columnar neuron that projects into the central brain to terminate in the intermediate zone of the anterior optic tubercle (AOTU) (Omoto et al., 2017; Hulse et al., 2021). Its dendritic arbors are found in medulla layer M6, in a different sublayer than the MC61 cells, and also in medulla layers M2 and M8 (Timaeus et al., 2020).[ FlyBase:FBrf0235330 FlyBase:FBrf0247314 FlyBase:FBrf0254510 ]
Also Known As "MC64" ; "medulla columnar 64 neuron" ; "MeTu-intermediate" (for all, see Synonyms field below)
Comment Timaeus et al. (2020) say that these cells also innervate the lobula, but do not reference a figure or paper and it is not clear whether this is a subset or the whole population. Timaeus et al. (2020) also say that these cells do not appear to follow a topographic organization between the medulla and AOTU, but topographic organization was seen by Garner et al. (2024).
