Taste buds are the peripheral sensory organs for gustation, the chemical sense that guides humans and nonhuman animals to determine the nutritive and hedonic values of ingested foods and to avoid consumption of potentially harmful substances. Taste buds consist of collections of taste cells that respond to sweet, bitter, sour, salty, and umami tastes and transmit this information to higher centers in the brain. Recent research has uncovered many of the molecular mechanisms underlying the initial events of taste transduction and show that some degree of information processing takes place in taste buds.
