Abstract
A method of integration of the total electrical activity recorded on the taste nerve was developed so that the response to any given chemical stimulation of the tongue of the rat could be measured and analyzed quantitatively. Single nerve fiber recordings were used complementary to the integration. All substances were flowed over a given and constant area of the tongue. Latency, rates of adaptation, prolonged discharge, and magnitudes of responses to various concns. were measured for a no. of salts. The relative sizes of integrated responses to 0.1 [image] concns. were as follows: HC1> LiCl [greater than or equal to] NaCl > NH4Cl>CaCl2 [greater than or equal to] SrCl2 [greater than or equal to] BaCl2 [greater than or equal to] MgCl2 > RbCl [greater than or equal to] KC1 [greater than or equal to] CsCl. A saturation level was found to exist at high concns. This level was observed to be different for each cation.Keywords
