In 1901, a German scientist published an article on taste research, describing the phenomenon that certain areas of the tongue of some people are more sensitive to a particular sense of taste, which is not a clear scientific conclusion. but people mistakenly think that several areas on the tongue are only responsible for a specific sense of taste. Later, this fallacy was translated into English by Edwin G. Boring, a psychiatrist at Harvard University, and spread widely. After that, people have a gradually in-depth study of taste, and found that this is not the case.

Because the taste bud also contains 50-150 taste receptor cells, and taste is transmitted to the brain through these taste receptor cells. However, whether each taste receptor cell can transmit only one taste or several flavors is controversial in academic circles.

One theory is to support the "dedicated line transmission model", in which a taste receptor cell recognizes only one taste, and a nerve fiber transmits only one taste signal. And some researchers have found that taste receptor cells support a dedicated line transport model through mouse experiments.

Another theory is to support the "cross fiber model", in which the same smell is transmitted into different cells or nerve fibers, and the taste stimulation information is encoded before it reaches the nerve fibers. and after entering the nerve fiber, a common circuit is used for signal transmission.

But no matter which model, a taste bud can taste all kinds of flavors at the same time. So the so-called "taste map" does not exist, even if you lick the lemon with the tip of your tongue, you can still taste the sour taste. By the same token, if you put the "five kernel moon cakes" on the base of your tongue, you can also taste the sweet and greasy taste.
