That afterimage is your sensory memory.

那个残像就是你的感官记忆。

These afterimages could be imagined as rippling outward from any primary construction.Theoretically there would be no end to these.They vary of course in intensity.

这些后影像可以想像成从任何一个主建构向外扩散的涟漪。理论上，这是没有尽头的。当然它们的强度也各自不同。

And an afterimage is something that a photograph can never replace, you never feel that in a photograph.

残像是照片永远无法取代的东西，你永远不会在照片中感受到这一点。

That's why you saw an afterimage for several seconds until all your cones were turned back up to full sensitivity.

这就是为什么你会看到几秒钟的残像，直到你所有的视锥细胞都恢复到完全灵敏度。

And this is an image of a work from Japan that you can see the afterimage of in the subway.

这是一张来自日本的作品的图像，你可以在地铁中看到它的残影。

But not all illusions work that way. Some produce ghost effects, or afterimages, that take advantage of glitches in the physiology of human vision.

但并不是所有的错觉都是这样的。有些会利用人类视觉生理的故障产生幽灵效应或残影。

So this is an afterimage of the painting made in my memory, and even that painting can fade as memory does.

所以这是我记忆中画的残影，甚至那幅画也会像记忆一样褪色。

And now when you stare at the white, what most people see is a faint afterimage of the flag in its normal colors.

现在， 当你盯着白色看时，大多数人看到的是旗帜正常颜色的微弱残像。

The same thing happened to your rods. Except, since they only register black and white, the afterimage was like looking at a negative of a photograph — dark replaced with light.

你的视杆细胞也发生了同样的事情。除了，因为它们只记录黑白，残影就像看照片的底片——黑暗被光明取代。

So, your eyes were still receiving red, green, and blue light — but only the red cones were able to respond. As a result, when the afterimage began to appear, those stripes looked red.

所以，你的眼睛仍然接收红色、绿色和蓝色的光——但只有红色的视锥能做出反应。因此，当残影开始出现时，这些条纹看起来是红色的。

Why does staring at this flag and then looking at an empty white space make us see a phantom flag of different colors? Well, it begins with the fact that our photoreceptors can make us see afterimages.

为什么盯着这面旗帜，然后看着一个空白的空白，会让我们看到不同颜色的幻影旗帜？嗯，它始于我们的光感受器可以让我们看到残影。
