A Neurobehavioral Analysis of I-Amino Acids as Taste Stimuli

We have described several aspects of amino acid gustatory stimulation in this report. Most convey the same message: despite some peculiarities in response time courses, amino acids bear striking similarities to the salts, acids and sugars which the majority of investigators use as taste stimuli.
