part of adult transverse antennal lobe tract fly_anatomy.ontology tALT Some of the projection neurons that fasciculate with the tALT send collateral branches to the ring neuropil via the superior section of the posterior lateral fascicle (PLF) (Tanaka et al., 2012). medial-mediolateral antenno-protocerebral tract VFB:FBbt_00007482 FBbt:00007482 Smaller tract that shares a common root (dorsomedial root) with the medial antennal lobe tract (mALT) and mediolateral antennal lobe tract (mlALT) and connects the antennal lobe to the mushroom body calyx, lateral horn or posterior lateral protocerebrum. Fibers can run above, through or below the mushroom body pedunculus, running posterior to the fan-shaped body.
