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. fly_anatomy.ontology FBbt:00007415 VFB:FBbt_00007415 AL-mPN4 atypical multiglomerular PN posterior lateral protocerebrum adult multiglomerular antennal lobe projection neuron lPN bilateral antennal lobe projection neuron antennal lobe projection neuron to mushroom body adult antennal lobe projection neuron to lateral horn medial antennal lobe tract projection neuron antennal lobe hub
