I know that the reason that sequence of still images appear to be moving, is an effect known a "Beta movement" that says if images move fast enough, our brain can't comprehend them as separate images and illusion of motion is created.
But the thought comes to mind is; what if our brain works like a digital circuit with a crystal of specific frequency for sampling, in which the frequency of that crystal determines the sampling rate.
the main question is; "Is there such a crystal in our brain to control oscillatory activities"?
If even our eye frame rate relates to oscillatory activities of our brain?
