Latest Vomeronasal organ Stories
The world is full of dubious dating techniques, but is it possible to experience the sweet smell of success by spraying pheromones on ourselves? We investigate.
Nocturnal animals need their noses to stay alive.
Sexually naïve male mice respond differently to the chemical signals emitted by newborn pups than males that have mated and lived with pregnant females.
Sometimes, not finding what you are looking for can lead to even more interesting avenues of research. That is what a recent international research team found out when they were searching for a pheromone trigger for newborn infant suckling responses in mice.
The vomeronasal organ (VNO) is one of evolution's most direct enforcers.
Research from Karolinska Institutet shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth.
A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood – attracting dozens of other males eager to mate.
When it comes to the circuits that make up the olfactory system, it seems that less is more.
New research, published in the journal Development, by Dr. Anthony-Samuel LaMantia, professor of Pharmacology & Physiology and director of the newly formed GW Institute for Neuroscience, and his colleagues have identified the stem cells that generate three critical classes of nerve cells â€“ olfactory receptors (ORNs), vomeronasal (VRNs) and gonadotropin releasing hormone (GnRH) neurons â€“ that are responsible for enabling animals and humans, to eat, interact socially and reproduce.
Scientists from The Scripps Research Institute have found a specific chemical compound secreted by many predators that makes mice behave fearfully.
- The horn of a unicorn considered as a medical or pharmacological ingredient.
- A winged horse with a single horn on its head; a winged unicorn.
