In experiments with 7 human observers the recognition of side and direction of the even and non-even (compensating the magnification factor) light motion in the left or right visual hemifield and to or from the fixation point was studied. The onset of the movement coincided with different phases of the EEG alpha-wave in the occipital region. In a control study stimuli were presented irrespectively to alpha-wave phases. Synchronization of non-even motion with some of the alpha-wave phases lead to an increase of its recognition probability and relative shortening of the response latency for directions from the center of gaze, while opposite directions became worse recognized and evoked relatively long-latency responses. Recognition of the even motion was not changed in experiment in compare with control. The obtained date are discussed in relation to Pitts and McCulloch (1947) hypothesis on a periodical (with alpha-wave frequency) scanning wave spreading over the visual cortex.
在对7名人类观察者进行的实验中，研究了在左或右视觉半视野中，向或背离注视点的均匀和非均匀（补偿放大因子）光运动的方向和侧面的识别情况。运动的起始与枕叶区域脑电图α波的不同相位一致。在对照研究中，刺激的呈现与α波相位无关。非均匀运动与某些α波相位的同步导致其识别概率增加，并且从注视中心方向的反应潜伏期相对缩短，而相反方向的识别变差并引发相对较长潜伏期的反应。与对照相比，均匀运动的识别在实验中没有变化。所得数据根据皮茨和麦卡洛克（1947年）关于在视觉皮层上传播的周期性（以α波频率）扫描波的假设进行了讨论。
