In order to reveal the information processing mechanism of gustation in the brain, the input-output relation in frog gustatory linguo-hypoglossal reflexes was studied. The mean number of impulses obtained from the experiments with single fungiform papilla preparations and the mean amplitude of integrated reflex responses obtained from the experiments with unanesthetized frogs were employed as the magnitudes of input and output information, respectively. The slope of the curve of input-output relation obtained was not so steep, indicating that the pathway of frog gustatory linguo-hypoglossal reflexes may be relatively simple, probably disynaptic.
