The effect of visual information processing of a rotating visual scene on postural responses of a standing subject was studied. Rotation of a scene induced postural sway movements involving rotations in the ankle joint. For modulation frequencies of rotation below 0.3 Hz, a clear correlation was found between the visual stimulus and the postural movements in the lateral direction. The amplitude of postural movements appeared to be independent of the angular velocity of the rotation of the scene if the angular velocity exceeded 5 deg/sec for sinusoidally modulated rotations or 10 deg/sec (rms values) for randomly modulated rotations. To facilitate distinction between the contributions from visual information processing of the incoming visual stimuli and from the motor system, a model is presented that explains some aspects of visuo-motor interaction.
研究了旋转视觉场景的视觉信息处理对站立受试者姿势反应的影响。场景的旋转诱发了涉及踝关节旋转的姿势摇摆运动。对于低于0.3Hz的旋转调制频率，在视觉刺激与横向姿势运动之间发现了明显的相关性。如果正弦调制旋转的角速度超过5度/秒或随机调制旋转的角速度超过10度/秒（均方根值），姿势运动的幅度似乎与场景旋转的角速度无关。为了便于区分来自传入视觉刺激的视觉信息处理和运动系统的贡献，提出了一个解释视觉-运动相互作用某些方面的模型。
