Broca’s Theory Is Myth; Humans Can Smell As Well As Animals

Since time immemorial, it has been widely believed that the smelling sensation of humans is weaker than that of animals. In fact, French neuro-anatomist that went by the name of Paul Broca even attested to this statement back in 1879 by supporting it with his research. However, surprisingly-enough it appears like this is just a myth that - on the basis of half-baked research and rumours - been blindly carried on from generation to generation.

According to a reports, thanks to the given science advancements, researchers have been able to prove Broca's theory to be wrong. Neuro-scientist from Rutgers University John McGann along with his team of researchers has been studying this subject for quite a long time. After a long time of study, they have discovered that human nose has more to it than meets the eye.

Their research - which was funded by the National Institute of Mental Health (NIMH) and the National Institute on deafness and other Communication Disorders (NIDCD) - suggests that human nose in comparison to other mammals such as mouse, dog or goat have smaller size olfactory bulbs, which are most primarily responsible for detecting smell senses.

As also reported by Community Daily News, the researchers discovered that it's not that the human sense is inferior to that of animals, but there is another reason why the animals are faster when it comes to detecting different kind of smells. Moreover, they even further discovered that humans have far lesser olfactory bulbs in comparison to other animals such as dogs.

Yahoo! News even reported stating that it is essential that the neuro-transmitters present in the brain of all mammals are well connected with these olfactory bulbs which are primarily responsible for the smelling sensation. For more updates and news on science, stay tuned.
