General Information
Term embryonic/larval antennal lobe ID (Ontology) FBbt:00007127 (Fly Anatomy)
Definition 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.[ FlyBase:FBrf0155900 FlyBase:FBrf0208205 FlyBase:FBrf0211016 ]
Also Known As "antennal compartment" ; "BA" ; "baso-anterior synaptic neuropil domain" (for all, see Synonyms field below)
Comment Note - description of relative location of brain structures in this definition is based on Younossi-Hartenstein et al., 2003 description of the first instar larval brain and Pereanu et al., 2010 third instar larval brain.
