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.
Taste buds, the main receptor for taste stimuli, are located in the papillae scattered throughout the mouth. They are so small that they are visible only with a microscope. A person's tongue has about 10,000 taste buds.
