Pheromones are substances that facilitate chemical communication between members of the same species.
Most mammals have a special pheromone receptor located at the base of the nasal septum called the Jacobson’s organ, which is useful in the process of communicating chemical messages such as readiness for sexual activity, between members of the same species.
According to research this organ fulfills no function in humans anymore.
However, researchers at the Ruhr University in Germany and other institutes have demonstrated (using genetic-analysis techniques) that pheromone receptors also occur in the olfactory epithelium (located in the nasal cavity involved in smell) in humans and in mice.
This pheromone receptor has been detected and activated by using the potent substance ‘Hedione’ extracted from Jasmine essence
Hedione is one of the most popular perfume materials used. It has been described as bringing a ray of sunshine into a fragrance.
They then analysed what happens in the brain when Hedione is smelled. The results were remarkable…
Hedione activated the Limbic system (the area in the brain associated with emotions and feelings) very significantly in comparison to other fragrances.
In addition, Hedione activated the brains hormone control centre in a typical pattern that is recognised as connected to sexual behaviour.
The team headed by Prof Dr Thomas Hummel in Germany are beginning the next stages of the research. To find out which physiological and psychological parameters are affected by Hedione stimulating the pheromone receptor in humans, and to search for traces of the scent molecules in bodily secretions which resemble Hedione.
“Humans could actually communicate with each other via Pheromones"
says Hanns Hatt a member of the research team.
