根据前庭眼球震颤和扫视的时间过程形状和振幅-持续时间关系，比较了警觉完整猴前庭眼球震颤和扫视的快速相。当眼球震颤是由旋转自然引起时，这两种快速运动几乎相同。视野结构、光照和黑暗对两种运动的速度影响相似。这表明同一个运动前神经回路可能同时产生扫视和快速阶段。当眼球震颤是人为造成的（如热量或电刺激），快相是相当不正常的；它们的速度降低了2到3倍。
Quick phases of vestibular nystagmus and saccades were compared on the basis of the shape of their time courses and their amplitude-duration relationships in the alert intact monkey. Both rapid movements are almost identical when nystagmus is induced naturally by rotation. Visual field structure, illumination and darkness affect the speed of both types of movements similarly. This indicates that the same pre-motor neural circuit probably creates both saccades and quick phases. When nystagmus is created artificially (e.g. caloric or electrical stimulation) the quick phases are quite abnormal; their speed being reduced by a factor of two to three.
