General Information

Term

mushroom body medial lobe arborizing neuron 7

ID (Ontology)

FBbt:00100235 (Fly Anatomy)

Definition

A neuron, which is part of a cluster of approximately two neurons per brain hemisphere, whose cell body is found in the inferior neuropils, anterior to the medial lobe of the adult brain. The cell body fibers project mediodorsally and bifurcate in the inferior neuropils. One branch arborizes here and the other runs ventromedially in the anterior surface of the medial lobe and innervates the gamma lobe.[ FlyBase:FBrf0205263 ]

Also Known As

"MB-M7"

Comment

Names are assigned according to the area of the mushroom body they arborize, as detailed in Tanaka et al. (2008). A precise number for the MB-M7 neurons was not possible by Tanaka et al. (2008) due to the enhancer trap they used (NP2297) also labelling the cell bodies of other neurons in close proximity. Also, because the arborization pattern of the MB-CP1, MB-M1 and MB-M7 intermingle, it was not possible to distinguish arborization areas for each population.
