This still image was created by a Japanese neurology professor Yamamoto, and he told the instructions below:
If its not moving, or just moving a little, you are healthy and has slept well.
If its moving slowly, you are a bit stressed or tired
If its moving continuously, you are over-stressedWell…fuck
It keeps spinning faster when I look away and slows to a crawl when I look directly at it. What’s that mean?
