It is divided into approximately 50 glomeruli and is clearly separated from adjacent neuropil domains by an extensive glial sheath. The two antennal lobes are connected by the antennal commissure and receive olfactory receptor neuron axons from the antennal nerve and subesophageal tract. It is also connected to the antennal lobe tracts and the broad root. VFB:FBbt_00007401 AL FBbt:00007401 fly_anatomy.ontology adult olfactory lobe
