TASTE

                 Taste is a chemical sense. Chemicals within food react with the gustatory cells to create neural impulses. The basal cells transfer these impulses to the brain. The 5 taste sensations are sweet, sour, salty, bitter, umami.

                Sensory interaction refers to the interaction of more than one sense and how they effect each other. Example: food tastes more bland when a person has a stuffy nose and can't smell properly.  Tongue Map myth is the notion that only certain parts of the tongue can sense certain sensations. This is wrong, any part of the tongue can test any sensation.
