The optical motional illusion shown below, makes your brain see some motion, where there is none.
In my opinion it's fascinating, although after a while you get a headache. It reminds me of binaural beats, where the brain simulates the difference tone, which is obviously not there. The way that these illusions work is obviously quite different than how binaural beats work, as stated in the comments.
Despite that, it's said that the beats stimulate your brain, so my questions are
- What is the name of this optical illusion?
Akiyoshi Kitaoka studied these kind of optimized Fraser-Wilcox illusions.
- Does it affect the brain in a similar way to binaural beats? I mean the overall effect, not the specific way how Fraser-Wilcox illusions or binaural beats enter your mind.
