Dynamic characteristics of the horizontal vestibulo-ocular reflex (HVOR), the optokinetic response (OKR), and their interactions were investigated in alert albino rabbits. For stimulation of the horizontal semicircular canals, the whole rabbit was rotated sinusoidally on a motor-driven turntable at peak-to-peak amplitudes of 5 degrees to 30 degrees over a frequency range of 1/30 to 1/2 Hz. Optokinetic stimulation was provided by a narrow vertical slit light source presented in front of the eye to be tested. The evoked horizontal eye movements were observed and measured by means of a closed circuit television system adapted to provide an analog signal proportional to the eye movement. The net HVOR was obtained by rotation of the turntable in darkness and the net OKR by rotation of the light source. Combining rotation of the turntable with a stationary light source immediately increased the gain and reduced the phase shift of the HVOR. The light source moving in phase with the turntable, but at twice the angular amplitude, reduced the gain and advanced the phase of the HVOR. Eye movement curves of the HVOR modified by a fixed or moving slit light could be reconstructed approximately by a linear combination of the net HVOR and OKR.
在警觉的白化兔中研究了水平前庭眼反射（HVOR）、视动反应（OKR）的动态特性及其相互作用。为刺激水平半规管，将整只兔子置于电动转台上进行正弦旋转，峰峰值幅度为5度至30度，频率范围为1/30至1/2赫兹。通过在受试眼前呈现窄垂直狭缝光源来提供视动刺激。借助适用于提供与眼动成比例的模拟信号的闭路电视系统观察和测量诱发的水平眼动。通过在黑暗中转台旋转获得净HVOR，通过光源旋转获得净OKR。将转台旋转与固定光源相结合会立即增加HVOR的增益并减小其相移。与转台同相但角幅度为两倍的光源移动会降低HVOR的增益并使其相位提前。由固定或移动狭缝光改变的HVOR的眼动曲线可通过净HVOR和OKR的线性组合大致重建。
