味觉体验的一些主观可变性可能与味蕾密度的广泛差异有关。对味觉的研究表明，感觉和感受器的数量之间存在直接关系。在这项研究中，味蕾密度被量化，使用光学显微镜重建18个身体舌头的两个区域。标本来自男性和女性身体，分别代表三个年龄段：年轻人、中年人和老年人。结果显示，味蕾密度在年龄组和性别之间均匀分布，范围超过100倍。这种差异不是由于成年人死前的健康状况造成的，这一点在文献中得到了证实。味蕾密度在不同年龄段之间的差异可能会混淆一些关于衰老对味觉敏感度的影响的推断，这些推论是从对人类群体的横断面研究中得出的。从数据中还不清楚人类味蕾密度在个体和群体中是稳定的还是随着时间的变化而变化的。
Some of the subjective variability attributed to taste experience could be related to wide variations of taste bud density. Studies of taste perception show a direct relationship between sensation and the number of receptors. Taste bud densities are quantified in this study using light microscopy to reconstruct two regions of 18 human cadaver tongues. Specimens came from male and female cadavers representing three age groups: young adults, middle-aged adults, and older adults. The results show a range of more than 100-fold in taste bud density that is evenly distributed among age groups and sexes. The disparity is not attributable to the state of health of the adults prior to death, and it is corroborated in the literature. Differences in taste bud density that extend across age groups probably confound some inferences about the effects of aging on taste sensitivity that are derived from cross-sectional studies of human populations. It is not clear from the data whether or not human taste bud density in individuals and in populations is stable or changing with time.
