The influence of linear acceleration on optokinetic nystagmus (OKN) was studied in human subjects. Linear acceleration was applied to the subjects by means of the parallel swing and also by the transfer of the subjects in one direction, either right or left. The cortical form of OKN increased the frequency, amplitude, and eye speed of the slow phase. Of the three, the increase in eye speed was the most pronounced. The subcortical form of OKN was not only increased but was also disturbed by the linear acceleration. When the compensatory eye movement with linear acceleration and the slow phase of OKN were in the same direction, the nystagmus increased remarkably. Contrarily, when the two directions were opposed to each other, nystagmus was inhibited. These results proved that the otolithic organs are not only able to promote but also to inhibit visual function.
研究了线性加速度对人体视动性眼震（OKN）的影响。通过平行摆动以及让受试者向左或向右单向移动的方式，对受试者施加线性加速度。OKN的皮质形式增加了慢相的频率、幅度和眼球速度。这三者中，眼球速度的增加最为明显。OKN的皮质下形式不仅增加，而且受到线性加速度的干扰。当线性加速度引起的代偿性眼球运动与OKN的慢相方向相同时，眼震显著增加。相反，当两个方向相反时，眼震受到抑制。这些结果证明，耳石器官不仅能够促进视觉功能，还能够抑制视觉功能。
