连续呈现的玻璃图案（随机定位的点对，以连贯的图案取向）产生了强烈的整体运动感，沿着图案的取向，但方向模糊。在这里，我们报告说，动态的“反玻璃”模式，由连续对全球结构对相反的极性，创造一个更强大的运动错觉，是明确的方向：黑点总是朝着光移动。通过在光点的呈现中引入真实的延迟，可以取消和逆转该运动，这表明光的有效刺激比黑点快约3 ms。对此最合理的解释是，人类的ON通道比OFF通道快，正如猕猴所示。
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.
