通过对7名正常人的实验研究，探讨了被动头部运动对光动力诱导的错觉自旋的抑制作用。视觉仿真由伺服控制的光动鼓提供。每个受试者参加两个实验环节。在一种情况下，受试者的头部保持静止，而他被动地盯着一个移动的条纹图案。在另一种情况下，他被动地凝视，放松颈部肌肉，同时他的头从一边转到另一边。这似乎是由于一种空间恒常机制的运作，将视觉、前庭和动觉信息在持续的身体方向上相互联系起来，从而抑制了光动力诱导的被动头部运动的虚幻自旋。研究结果支持这样一种观点，即光动性“晕动病”至少在一定程度上与眼动性障碍有关，而不是视觉引发的特定前庭病因障碍。
An experimental study was conducted on seven normal subjects to evaluate the effectiveness of passive head movements in suppressing the optokinetically-induced illusory self-rotation. Visual simulation was provided by a servo-controlled optokinetic drum. Each subject participated in two experimental sessions. In one condition, the subject's head remained stationary while he gazed passively at a moving stripe pattern. In the other, he gazed passively and relaxed his neck muscles while his head was rotated from side to side. It appears that suppression of optokinetically-induced illusory self-rotation with passive head movements results from the operation of a spatial constancy mechanism interrelating visual, vestibular, and kinesthetic information on ongoing body orientation. The results support the view that optokinetic 'motion sickness' is related, at least in part, to an oculomotor disturbance rather than a visually triggered disturbance of specifically vestibular etiology.
