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. [...] As such, the study calls into question whether the mixing of smell and taste first happens in the brain. Instead, it provides evidence suggesting the process that creates flavor may first happen in the tongue.
