Gustatory system

Definition

The gustatory system is the sensory system responsible for the perception of taste and flavour. In humans, the gustatory system is comprised of taste cells in the mouth (which sense the five taste modalities: salty, sweet, bitter, sour and umami), several cranial nerves, and the gustatory cortex.

    Mammals detect the nutrient content, palatability and potential toxicity of food through taste buds that are present mainly in the tongue. In this Review, Roper and Chaudhari discuss the taste bud cells, receptors and transmitters that are involved in taste detection, how these cells communicate with sensory afferent fibres, and peripheral taste coding.

    The authors find that mammalian acid-sensing taste receptor cells, previously shown to be putative sour taste sensors, also mediate responses to water. Optogenetic activation of this population of cells in thirsty mice induced robust drinking response in the absence of water. This study shows that acid-sensing TRCs contribute to the detection of water in the oral cavity.

    Nutrients taste perception is mediated by T1r receptors that discriminate specific tastes among their wide diversity. Here the authors present crystal structures of the ligand-binding domains of the fish T1r2-T1r3 receptor, providing a structural framework for its ligand recognition.
