Psychophysical responses to chemical stimulation of single human fungiform taste papillae were obtained from 40 papillae in four subjects. Effects of solution concentration and locus of stimulation were examined for nine test compounds. Sensitivity profiles constructed for individual papillae showed that single fungiform papillae mediate more than a single taste quality. In addition, the chemical sensitivities of individual papillae were reflected in their thresholds for all compounds, and correlation coefficients between recognition thresholds were no greater for similar than for dissimilar tasting compounds. No differences in mediation of quality were found as a function of locus of stimulation on the papilla, although sensitivity was found to be greater on the dorsal surface than on the sides. The data were discussed within the context of previous studies of response characteristics of single papilla.
从4名受试者的40个菌状乳头获得了对单个人类菌状乳头化学刺激的心理物理反应。针对9种测试化合物研究了溶液浓度和刺激部位的影响。为单个乳头构建的敏感性曲线表明，单个菌状乳头介导的味觉质量不止一种。此外，单个乳头的化学敏感性反映在它们对所有化合物的阈值上，相似味觉化合物之间识别阈值的相关系数并不比不同味觉化合物之间的更大。尽管发现背侧表面的敏感性高于侧面，但未发现刺激乳头部位对味觉介导有差异。在先前关于单个乳头反应特征的研究背景下对数据进行了讨论。
