There Is No Taste Map On The Tongue
According to professor Steven D. Munger of the University of Florida, the taste map on the tongue is utter nonsense. It all started when a German scientist’s findings got published in a paper in 1901. His study included a graph that misrepresented his research.
The graph kind of made it seem like the human tongue had its own “taste map” and people took it literally, so for years, everyone believed this to be true. But the receptors that can detect salty, sour, sweet, bitter, and umami are distributed all around your tongue.
