Abstract
Taste substances were administered to the frogs tongue treated with acetylcholine (ACh) in 10% propylene glycol solution and 2-dimethylaminoethanol (DMAE) which is considered to be precursor of ACh in animal body, and the changes in the sense of taste were studied by electrophysiological method. As a result, it was found that sense of taste was enhaced after trastment of the tongue with ACh as compared with before treatment. In addition, a phenomenon of sustained action of sense of taste was observed with DMAE. This suggests that as ACh-like substance may play an important role in the transmission of sense of taste.
