Thus it has been argued that such studies, employing macroscopic observational methods, have sometimes misidentified or even missed the vomeronasal organ. [45] Among studies that use microanatomical methods, there is no reported evidence that human beings have active sensory neurons like those in working vomeronasal systems of other animals. [46]
Thus it has been argued that such studies, employing macroscopic observational methods, have sometimes missed or even misidentified the vomeronasal organ. [36] Among studies that use microanatomical methods, there is no reported evidence that human beings have active sensory neurons like those in other animals' working vomeronasal systems.
[23] [41] [42] [43] Currently, no structure of the vomeronasal organ has been elucidated in Old World monkeys, although it has been shown that an apparent vestigial vomeronasal organ develops but degenerates before birth. [23] Conversely, human embryos possess a vomeronasal organ that persists, although this feature is vestigial throughout ...
The sensory receptors of the accessory olfactory system are located in the vomeronasal organ. As in the main olfactory system, the axons of these sensory neurons project from the vomeronasal organ to the accessory olfactory bulb, which in the mouse is located on the dorsal-posterior portion of the main olfactory bulb.
In vertebrates, the accessory olfactory bulb (AOB), which resides on the dorsal-posterior region of the main olfactory bulb, forms a parallel pathway independent from the main olfactory bulb. The vomeronasal organ sends projections to the accessory olfactory bulb [15] [16] making it the second processing stage of the accessory olfactory system ...
Rabbits have a specialized organ called the Jacobsen’s organ, or the vomeronasal organ. This organ is used to detect and process the pheromones they use to communicate.

The vomeronasal organ, also called Jacobson's organ, is a chemoreceptor organ named for its closeness to the vomer and nasal bones, and is particularly developed in animals such as cats (who adopt a characteristic pose called the Flehmen reaction or flehming when making use of it), and is thought to have to do with the perception of certain ...
