The researchers add that stress is also known to increase intake of salty foods. But in this study, the team did not find any GC receptors in taste buds associated with salty and sour tastes. Parker says this may be because stress could have an influence on salt taste processing in the brain. Taste buds are not only found on the tongue; they are also present in the gut and pancreas.
These cells transmit messages to the brain, where specific smells or tastes are identified. 1  Olfactory (smell nerve) cells are stimulated by the odors around usthe fragrance from a rose, the smell of bread baking.  Gustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat. They react to food or drink mixed with saliva. Many of the small bumps that can be seen on the tongue contain taste buds. These surface cells send taste information to nearby nerve fibers, which send messages to the brain.
