General Information
Term mushroom body medial lobe arborizing neuron 1 ID (Ontology) FBbt:00100229 (Fly Anatomy)
Definition A neuron, whose cell body is located in front of the inferior neuropils, anterior to the middle part of the medial lobe of the adult brain. A neurite projects dorsolaterally and forms arborizations further in the inferior neuropils and within the superior neuropils. Some of these branches extend ventromedially and arborize in the medial-most segment of the gamma lobe (slice 5) and the slice 2 beta-s and slice 2 beta'-a strata (Tanaka et al., 2008). Some of the fibers further project to the contralateral medial lobes.[ FlyBase:FBrf0205263 ]
Also Known As"MB-M1" ; "MB-M1 neuron"
CommentNames are assigned according to the area of the mushroom body they arborize, as detailed in Tanaka et al. (2008).
