neural adaptation vs constant stimulus

Did you know that photoreceptors are attached to the cells IN FRONT of them, so they are always ‘seeing’ the cells. The reason as to why you can’t actually see them is because your brain erases all the things that are constant in your visual field. When presented with a constant stimulus, your brain decides it’s not important (’cause it ain’t moving) and just erases it.

Here’s a cool example:

Keep staring at the centre and after a while the yellow dots will  disappear. If that’s hard then just focus on one dot and the other two will disappear after a while.

Side note: is this a good allegory for staying relevant in the world of social activism?
