The receptors that dot our noses and help us to smell also populate our tongues, according to a new study. Researchers at the Monell Chemical Senses Center have discovered working olfactory (smell) receptors in the taste-sensing cells on the papillae of the tongue. The findings were published in the journal Chemical Senses.
It is thought that the systems that enable us and other mammals to taste and smell are separate, and our brains combine this information so we can experience flavor. While the tongue deals with whether food is salty, sweet, sour, bitter, or umami, our noses provide more detail from smells.
