In 1911 Wilson reported the presence of modified Vater-Pacinian corpuscles in the human tympanic membrane. Our ultrastructural study of the corpuscles revealed that their features are comparable to the function of a mechanoreceptor. The location of the corpuscles indicate that they may detect the stiffness of the tympanic membrane as a result of its dislocation. Based on histological findings, the relation between mechanoreceptors in the tympanic membrane and the tubal function was examined. Tubal function was tested during Valsalva maneuvers and its active equilibration. After anesthesia of the tympanic membrane, 13 out of the 40 ears needed more than two swallows. As Eustachian tubal function changed following anesthesia of tympanic membranes, a neural connection between sensory receptors in the tympanic membrane and tubal muscles is suggested.
1911年，威尔逊报告在人鼓膜中存在改良的 Vater 小体（环层小体）。我们对这些小体的超微结构研究表明，它们的特征与机械感受器的功能相当。这些小体的位置表明，它们可能由于鼓膜移位而检测到鼓膜的硬度。基于组织学发现，研究了鼓膜中的机械感受器与咽鼓管功能之间的关系。在瓦尔萨尔瓦动作及其主动平衡过程中测试了咽鼓管功能。在鼓膜麻醉后，40只耳朵中有13只需要吞咽两次以上。由于鼓膜麻醉后咽鼓管功能发生变化，提示鼓膜中的感觉感受器与咽鼓管肌肉之间存在神经连接。
