General Information
Term medial antennal lobe tract projection neuron 4 ID (Ontology) FBbt:00007415 (Fly Anatomy)
Definition Adult antennal lobe (AL) projection neuron that is derived from the AL1l neuroblast lineage. It arborizes extensively in the AL hub and innervates multiple antennal lobe glomeruli. Its cell body is located in a lateral position in the cell body rind of the AL. The dendritic arbors of these neurons do not outline individual glomeruli. There is a bifurcation where one fiber enters the medial antennal lobe tract (mALT) and the other projects to the contralateral AL via the AL commissure. Axons project through the mALT to the mushroom body calyx and the lateral horn. A branch also projects via the posterior lateral fascicle to the posterior lateral protocerebrum. There are at least 13 cells of this type.[ FlyBase:FBrf0205814 FlyBase:FBrf0219809 FlyBase:FBrf0242628 ]
Also Known As "AL-mALT-PN4" ; "AL-mPN4" ; "atypical multiglomerular PN"
