Depression of the Neural Taste Responses by Chloroform and Bromoform in Fish

概要

To check effectiveness of chloroform and bromoform on the taste receptive membranes of carp (Cyprinus carpio L.), we recorded electrophysiologically the neural taste responses to L-amino acids during applications of several concentrations of the two chemicals in the artificial fresh water bathing the taste epithelia. The two compounds slightly elicited neural excitation by themselves, and have some effects on taste responses. Taste responsiveness for L-Ala and L-MSG were significantly depressed with the increase of concentration of chloroform and bromoform (0.001〜0.1mg/l). It is obvious that the latter affected the taste responses more strongly than the former does at the same concentrations. These results indicate that although chloroform and bromoform depressed the neural responses of the taste system somehow, it is not clear from the present experiments that these chemicals might cause anesthetic state on the taste membrane.
