Figure 4.
The accessory OB. This structure receives sensory input from the vomeronasal organ via the vomeronasal nerve, and is located on the dorsomedial surface of the caudal OB. The structure can be found just medial to the region in which the olfactory nerve and glomerular layer thin and then disappear. Medial to the AOB, the 2 regions that form the AON (AONpE) and AONpP emerge. Scale bar = 30 µm.
