Successive presentations of Glass patterns (randomly positioned pairs of dots oriented in a coherent pattern) create a strong sense of global motion along the orientation of the pattern, but ambiguous in direction. Here we report that dynamic "anti-Glass" patterns, created by successive pairs of globally structured pairs of opposite polarity, create an even more powerful motion illusion that is unambiguous in direction: the dark dots always move toward the light. The motion can be cancelled and reversed by introducing a real delay in the presentation of the light dots, suggesting that the effective stimulation of the light is about 3 ms faster than the dark dots. The most plausible explanation for this is that human on channels are faster than off channels, as has been shown in the macaque.
连续呈现格拉斯图案（以连贯图案定向的随机定位的点对）会产生一种沿着图案方向的强烈全局运动感，但方向不明确。在此我们报告，由连续的具有相反极性的全局结构化点对所创建的动态“反格拉斯”图案会产生一种方向明确且更加强烈的运动错觉：暗点总是朝着亮点移动。通过在亮点呈现中引入实际延迟，可以消除并反转这种运动，这表明光的有效刺激比暗点快约3毫秒。对此最合理的解释是，正如在猕猴身上所显示的那样，人类的开启通道比关闭通道更快。
