Behavioral responses to various inorganic chlorides and zinc compounds in rats were determined by the gradual two-bottle preference method. In the concentrations beyond the threshold for discrimination, rats had a rejective response to these test compounds. Two series of taste stimulating effects of the test compounds (epressed as a reciprocal of the threshold for discrimination) was obtained in the order of larger values (M) as follows: HgCl_2>ZnCl_2>PbCl_2≧CuCl_2>NiCl_2>BaCl_2>-FeCl_3>SnCl_2>LiCl>AlCl_3>MgCl_2>CaCl_2>SrCl_2>CsCl>KCl>NH_4Cl>NaCl, and ZnCl_2≧ZnSO_4≧Zn(N-O_3)_2≧Zn(CHCOO)_2. Neural responses of the chorda tympani nerve to these inorganic chlorides in rats were datermined and on the basis of the magnitude of initial phase of the integrated responses, a series of gustatory effectiveness of these inorganic chlorides was different from that above mentioned. Accordingly, an intimate relationship between these two series was not obtained.
