13. The role of the vomeronasal system in food preferences of the gray short-tailed opossum, Monodelphis domestica
Although feeding deficits have been reported in snakes and lizards following vomeronasal system disruption, no deficit has been previously reported in a mammal. We tested gray short-tailed opossums with items from four different food categories prior to occluding access to the vomeronasal organ. Preoperatively, opossums preferred meat to fruit or vegetables.

15. The development of the olfactory mucosa in the mouse: light microscopy.
The development of the olfactory and vomeronasal epithelia of the mouse has been investigated from the 9th day of gestation until shortly after birth. On the 10th day axons emerge from the base of the olfactory epithelium to reach the olfactory bulb primordia on the 11th day, at which time the olfactory dendrites first appear. On the 13th day a distinction b

17. The anatomy and histology of the nasal cavity of the koala (Phascolarctos cinereus).
The anatomy of the nose of the koala was studied from fixed 0.5 cm thick sections of a whole head. Right and left nasal cavities are separated by a slender septum which does not exhibit 'swell bodies'. Dorsal and ventral conchae are simple curved plates without elaborate scrolls; the ventral concha is recurved to form a bulla. The nasal cavity communicates w

18. Evolutionary deterioration of the vomeronasal pheromone transduction pathway in catarrhine primates
Pheromones are water-soluble chemicals released and sensed by individuals of the same species to elicit social and reproductive behaviors or physiological changes; they are perceived primarily by the vomeronasal organ (VNO) in terrestrial vertebrates. Humans and some related primates possess only vestigial VNOs and have no or significantly reduced abilit

19. Human Pheromone Detection by the Vomeronasal Organ: Unnecessary for Mate Selection?
Recently, Foltan and Sedy proposed a hypothesis stating that the adult human VNO is integral to the prevention of inappropriate mate selection. In this commentary, we address the authors’ assumption that humans have a functional VNO, that pheromones are detected exclusively by the VNO, and that human pheromones are responsible for negative stimuli during m

20. Olfactory expression of a single and highly variable V1r pheromone receptor-like gene in fish species
Sensory neurons expressing members of the seven-transmembrane V1r receptor superfamily allow mice to perceive pheromones. These receptors, which exhibit no sequence homology to any known protein except a weak similarity to taste receptors, have only been found in mammals. In the mouse, the V1r repertoire contains >150 members, which are expressed by neurons

21. Acceleration of puberty onset in female mice by male urinary proteins.
1. Puberty onset in female mice is accelerated by exposure to conspecific adult male urine, which acts through the vomeronasal organ and the accessory olfactory system. A distinctive component of adult male mouse urine is the major urinary protein complex (MUP), which is a lipocalin; it has a hydrophobic pocket that binds small endogenous volatile molecules.

22. Sequence Diversity and Genomic Organization of Vomeronasal Receptor Genes in the Mouse
The vomeronasal system of mice is thought to be specialized in the detection of pheromones. Two multigene families have been identified that encode proteins with seven putative transmembrane domains and that are expressed selectively in subsets of neurons of the vomeronasal organ. The products of these vomeronasal receptor (Vr) genes are regarded as candidat

23. TRP2: A candidate transduction channel for mammalian pheromone sensory signaling
The vomeronasal organ (VNO) of terrestrial vertebrates plays a key role in the detection of pheromones, chemicals released by animals that elicit stereotyped sexual and aggressive behaviors among conspecifics. Sensory transduction in the VNO appears unrelated to that in the vertebrate olfactory and visual systems: the putative pheromone receptors of the VNO

24. Direct influence of the sodium pump on the membrane potential of vomeronasal chemoreceptor neurones in frog.
1. Whole-cell measurements were made from microvillous receptor neurones isolated from the frog vomeronasal organ. We examined the mechanisms that determined the value of the resting membrane potential. 2. Cells recorded in Ringer solution containing 4 mM K+ showed a resting membrane potential of -88 +/- 20 mV (mean +/- 1 S.D., n = 56). Sixty-six per cent of
