OUR SENSE OF SMELL

DO YOU know that we smell in stereo?

Scent signals from each of our nostrils go to different parts of our brain. Scientists believe that this helps us work out where the smell is coming from.

There are about five million olfactory receptors in the membrane at the top of our nasal passages, which help us to distinguish among the thousands of smells we might encounter. - Innerbody.com;medterms.com
