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: HgCl2>ZnCl2>PbCl2≧CuCl2>NiCl2>BaCl2>FeCl3>SnCl2>LiCl>AlCl3>MgCl2
>CaCl2>SrCl2>CsCl>KCl>NH4Cl>NaCl, and ZnCl2≧ZnSO4≧Zn(NO3)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.
