FBbt:00007062 larval antennal lobe larval olfactory lobe antennal compartment Paired synaptic neuropil domain of the larval deutocerebrum, located ventral to the mushroom body, that is the major target of innervation for axons carried by the antennal nerve. It is also connected to the antero-basal tract (ABT). Its posterior boundary contacts the lateral accessory lobe, ventromedial cerebrum, ventrolateral protocerebrum and periesophageal neuropils. It is the larval counterpart of the adult antennal lobe, and consists of around 22 glomeruli. larval AL larval sensory compartment
