Abstract

Recent work on receptor molecules and cells used prototypical sweet, salty, sour, bitter, and umami stimuli. Labeled-line coding was supported, but it remains possible that the molecules and cells could respond to other tastants. Studies with other tastants are needed. The sensory message might contain two codes – one for attraction or aversion, the other, across-fiber patterning of stimulus quality.
