Handb Clin Neurol. 2019;164:173-185. doi: 10.1016/B978-0-444-63855-7.00011-3.


This chapter summarizes the available data about taste receptor functions and their role in perception of food with emphasis on the human system. In addition we illuminate the widespread presence of these receptors throughout the body and discuss some of their extraoral functions. Finally, we describe clinical aspects where taste receptor signaling could be relevant.

Keywords: Extraoral; GPCR; Gustation; Signaling; Taste.
