Why does perfume smell different from each other?

The scientific world finally deciphered why, with the same perfume, but each person felt a completely different smell.

American scientists discovered that we all experience smells in a completely different way. According to a new study report published in Nature Neuroscience, the human nose contains 400 senses separately and when comparing any two people together, the experts found 30% difference in these senses.

Dr. Joel Mainland, a molecular biologist at the Monell Chemical Center, and colleagues, discovered that a change in just one olfactory receptor could change the way a person feel about a single smell.

Dr. Mainland explains: "The type of activating 400 receptors in the human nose encodes both the intensity and the quality of the smell. Changing a certain receptor is synonymous, some people smell the smell of one. Some steroids (organic, soluble, natural or synthetic fats) like a pleasant sandalwood smell, while others give it a strong odor like urine. "

Mr. Mainland's group cloned the 511 sensory receptors and implanted them into the host cells in the laboratory. Then, they measured the reaction of each of these receptors with a table of 73 different scents. The process helped identify 28 different reactions to the odors of each type of receptor perception.

Using mathematical models to extrapolate results, the team concluded that, between any two people, there is a difference in 140/400 receptors, ie about 30%. According to Dr. Mainland, this difference rate is amazingly high, "implying a big difference in the sense of smell between you and me, when you smell an object".

Mr. Mainland said, the discovery could help scientists create exactly what they want."The long-term goal will be to find out the mechanism of olfactory receptors that encode scent molecules. From there, we can accurately invent any scent we want," the researcher said. , by directly manipulating these feelings. "
