Optical Illusion: Can You Follow This Spinning Effect?

If we look at this graphic, at first glance we see 7 circles on which tilted rectangles with beveled edges are arranged.
Otherwise, this graphic is not very spectacular. If we now change the size of the shape, the circles will start to rotate. The effect can be observed most clearly with the orange colored circles.
If we stop the graphics, the spinning effect will end.
The rotation is an illusion, which becomes clear when we move towards or away from the screen. Now the circles are clearly turning again.
But why is it like that?
Expanding outward as we approach the graphic, the white and black edges of the small shapes travel across the synapses of our retinas. Where there was just an edge, there is now an orange-colored surface or a gray one, our brain knows the effect from nature and thinks the surface has moved accordingly. Because the edges are slanted, our brain now perceives two different movements. The real on the outside and the deceived on the side.
The illusion has a name: it’s called the Pinna-Brelstaff illusion. Chinese scientists solved part of the mystery in 2019. It appears to be due to a communication delay between the regions of the brain that process vision.
The scientists found that macaques can also see the effect, and measured a delay of 15 milliseconds in their brains between the activity of the neurons that sense global movements and those that sense local movements.
In this case, the brain uses a shortcut, because the apparent movement is perceived first, it is difficult for the brain to understand that the graphic is actually not moving.
Optical illusions like this clearly show one thing: we cannot always rely on our perception.
