Taste Perception Uses Labeled Line Coding

This animated video demonstrates current models of how the mammalian tongue recognizes and discriminates the different odor qualities: salty, bitter, sour, sweet, and umami (M.S.G.). A taste bud on the tongue is depicted. Different types of tastes activate defined taste cells that are tuned to a given taste quality. Most of the data leading to this model were generated by the group of Charles S. Zuker at UCSD.
