| 摘 要： | 研究视动震颤眼动系统在同时包含两个二维运动的复合运动条纹刺激下的反应特性，并探讨两种子条纹运动方向的夹角和运动速度的影响。实验结果发现，在一定参数范围内，复合运动条纹引起了双重交替ＯＫＮ反应，即ＫＯＮ交替地跟踪合成运动和分别运动；在跟踪分别运动中，又是交替地跟踪两种子条纹的运动。 |
| 关 键 词： | 视觉 视动眼颤 复合运动条纹 |

| Abstract: | Optokinetic Nystagmus (OKN ) induced by moving compound gratings was investigated. It was found that OKN sometimes tracks the coherent motion of the rigid plaid in a single direction, and sometimes tracks alternately the transparent motion of two component gratings in different directions, as Dual Altemate OKN. It was also found that the duration of OKN tracking coherence increases as the moving speed of the component gratings d creases, and as the angle between their moving directions decreases. The results also showed that the effect of angle plays a dominant role. |
