The sense of taste is perceived by the brain through the interaction of taste buds and olfactory receptors. Taste buds are located on the tongue and detect the five basic tastes: sweet, sour, salty, bitter, and umami. Olfactory receptors, on the other hand, are located in the nasal cavity and detect the aroma of food. When we eat, the aroma of the food travels to the olfactory receptors through the back of the throat, which then sends signals to the brain to interpret the flavor of the food1.
