Understanding the way in which humans identify a particular smellOne of the senses in human beings is sense of smelling. Even if our eyes are closed we can smell the item and tell what it is. Some of the smells are so prominent that it is very easy to identify them. Many items are identified just by their smells. Flowers, fruits, cooked items, drinks, industrial atmosphere, restaurants, and so many other entities have a characteristic smell of their own.
There have been extensive research on how our nose is able to differentiate items based on the smell and though a lot has been deciphered but the exact mechanism is still a matter of research. The small feelers inside our nose are said to decode a smell and send the signal to the brain where it is recognised as a particular smell. It is a mystery as how the combination of these sensory elements inside the nose do it for each and every smell and same is yet to be resolved fully but it is well understood that it is more than a supercomputer claiming and having latest AI techniques.
