Abstract

28 animals were given a series of 4-min. drinking tests in a 2-choice situation, sucrose solution vs. water. Each test was preceded by forced-sampling of both liquids. The concentration at which 75% of the group made more tongue contacts with the sucrose solution was taken as the preference threshold. This concentration was .32 gm/100 cc of solution. This determination provides a baseline useful for the planning and evaluation of studies designed to map various sucrose isohedons for the rat on the basis of observations in the same test situation.
