Principle

At present, taste receptors for five different tastes (or taste qualities) are known: sweet, sour, bitter, salt and umami. Not every region of the tongue is sensitive, but each taste-sensitive region can perceive all taste qualities (otherwise, as assumed before). However, some taste qualities are more noticeable in certain areas of the tongue than in others, so the taste "sweet" is perceived stronger on the tip of the tongue while "bitter" is experienced more intensely on the back of the tongue.
