Humans can sniff-out truffles

/in /by

Our social and emotional states are influenced by our sense of smell. There apparently is no evidence that humans have an inferior sense of smell to that of most animals like rats, mice and dogs. As the human brain developed over time to become larger, the olfactory bulb grew proportionally. The statement that humans can only detect around 10,000 different odors is not founded in science rather science fiction. It is now believed that we should be able to detect up to a trillion different odors. Rats have a larger number of olfactory receptors than humans but that doesn’t inevitably mean that they can smell any better. The human olfactory system is made of an enormous number of neurons which is similar to that of a rat or dog. Rats and mice have genes that code for some 1,000 different receptors that are activated by odors while humans only have about 400, but again this speciously doesn’t make rodents better sniffers.
