説明

Abstract 1. 1. The eel palatine receptors were found to respond sensitively to carbon dioxide solution. 2. 2. Carbon dioxide solution of pH 5.0 gave a large response in the palatine nerve while hydrochloric acid solution of the same pH gave no response. Relationship between magnitude of the response and logarithmic CO 2 concentration at pH 5.0 was linear for a wide concentration range from 2 × 10 −5 M (threshold) to 2 × 10 −2 . 3. 3. Comparison between pH dependency of the response to carbon dioxide solution and that to phosphate buffer solution indicated that the palatine receptors respond specifically to CO 2 molecule and that HCO 3 − and CO 3 2− have no particular stimulating action compared with other inorganic anions.
