Reflex head and eye movements were observed in the guinea pig subjected to optokinetic stimulation and whole body oscillation in the yaw axis. Optokinetic stimuli induced low velocity head movements in the direction of the stimulus with stepwise movements in the opposite direction. With motion stimuli, the head was well stabilized in space and moved to new positions in stepwise manner; in the absence of vision the head was not able to maintain a stable position. The onset of a stepwise head movement was always synchronized with a saccadic eye movement in the same direction, the coordination being similar to voluntary movement. During good head stabilization, vestibular-ocular nystagmus did not occur. The guinea pig appears to avoid nystagmus by stabilizing its head preferentially. It is likely that the vestibular ocular reflex compensates for head displacement with unity gain in the frequency range of voluntary and stepwise reflex head movement and that a close relationship exists between the control of saccadic eye movements and that of voluntary or reflex head movement.
在经受视动刺激和绕偏航轴的全身振荡的豚鼠中观察到反射性头部和眼球运动。视动刺激诱发头部朝着刺激方向的低速运动，并伴有相反方向的阶梯式运动。在运动刺激下，头部在空间中得到良好稳定，并以阶梯式方式移动到新位置；在没有视觉的情况下，头部无法保持稳定位置。阶梯式头部运动的起始总是与相同方向的扫视眼球运动同步，这种协调类似于自主运动。在头部良好稳定期间，前庭眼动性眼球震颤未发生。豚鼠似乎通过优先稳定其头部来避免眼球震颤。前庭眼反射很可能在自主和阶梯式反射性头部运动的频率范围内以单位增益补偿头部位移，并且扫视眼球运动的控制与自主或反射性头部运动的控制之间存在密切关系。
