Abstract
The construction of an apparatus for electrical taste stimulation for clinical use is described. Investigations were carried out on 140 normal persons to determine the gustatory thresholds by an electric stimulus on the right and left sides of the anterior and posterior parts of the tongue. The results show that the thresholds in all age groups vary within very wide ranges, while there is no significant difference in thresholds determined on the right or left sides of the tongue. The method would appear to yield better results than does a semi-quantitative test using taste solutions of different concentrations.
