翻译后摘要：一个持续的水平眼震反应时，引起一个人是在恒定的速度旋转地球水平轴。该响应包括两个部分：方向偏差和偏差水平的循环调制。观察了三个刺激变量的影响：初始加速率，稳定旋转率和旋转轴的倾斜角。偏置和周期调制的影响不同的刺激变量，特别是稳定旋转的速度，这表明存在两个独立的反应机制。以前的实验表明，这两种机制依赖于耳石系统，虽然半规管贡献的可能性仍然存在。因此，可以合理地得出结论，这些响应组件提供了一种评估耳石调节响应的动态的方法。（作者）
Abstract : A persistent horizontal nystagmus response is elicited when a man is rotated at constant velocity about an Earth-horizontal axis. This response comprises two components: a directional bias and a cyclic modulation of the bias level. Observations were made of the effects of three stimulus variables: rate of initial acceleration, rate of steady rotation, and angle of tilt of the rotation axis. Bias and cyclic modulation were affected differently by stimulus variables, especially by rate of steady rotation, suggesting the presence of two separate response mechanisms. Previous experiments indicate that both mechanisms depend upon the otolith system, although the possibility of a semicircular canal contribution remains. Thus it is reasonable to conclude that these response components provide a means of assessing the dynamics of otolith-regulated responses. (Author)
