In this first article of four the problem is displayed using experiments on humans for two kinds of gravity related positions. In each case the nystagmus depends sinusoidally on a particular orientation of the canal to the vertical. In each case, too, a dissymmetry of the response occurs. This kind of behavior confirms that the caloric stimulation induces both a gravity dependent and a gravity independent effect. A simple mechanical model gives account of the gravity dependent effect. It does not imply the otolithic system. Since the cupula adheres to the ampullar wall and to the crista, this is a hydrostatic model in contrast to Bárány's model, which is of hydrodynamic type.
在这四篇系列文章的第一篇中，通过对人类进行的两种与重力相关姿势的实验展示了该问题。在每种情况下，眼震都呈正弦形式取决于半规管相对于垂直方向的特定取向。而且在每种情况下，反应都存在不对称性。这种行为证实了冷热刺激会诱发重力依赖性和重力非依赖性两种效应。一个简单的力学模型解释了重力依赖性效应。它并不涉及耳石系统。由于壶腹嵴帽附着于壶腹壁和嵴顶，所以这是一个静水压模型，与巴兰尼的流体动力学类型的模型形成对比。
