Thanks for posting an interesting question and motivating me to de-lurk.
don't have all my references at hand right now
Also, perception in the center (fovea) of the visual field is different than at the periphery
greyscale vision can have much more temporal accuracy than color vision

There is a common misconception in human thinking that our eyes can only interpret 30 Frames Per Second. This misconception dates back to the first human films where in fact a horse was filmed proving actually that at certain points they were resting on a single leg during running. These early films evolved to run at 24 Frames Per Second, which has been the standard for close to a century...
This is where this article gets even longer, but read on, please. I will explain to you how the Human Eye can perceive much past the
misconception of 30 FPS and well past 60 FPS, even surpassing 200 FPS....
to this i'm just wondering what where you interests lie (for want of a better phrase)for you to state 'references', is this subject reflective or your personal interests, or vocation...if you don't mind me asking
How does peception/the Visual Cortex make up the 'grey scale' of what its seeing?
This is how i see it. VISUALLY, the colour BLACK is the absence of colour. WHITE, as I understand it, is ALL the colours at once.

Actually humans do have a flicker. But that is really irrelevant to this scale. The Reis Limen or threshold of perception is 4ms.
The USAF, in testing their pilots for visual response time, used a simple test to see if the pilots could distinguish small changes in light. In their experiment a picture of an aircraft was flashed on a screen in a dark room at 1/220th of a second. Pilots were consistently able to "see" the afterimage as well as identify the aircraft. This simple and specific situation not only proves the ability to percieve 1 image within 1/220 of a second, but the ability to interpret higher FPS.
So what is "Enough fps"? I don't know, because nobody went there so far. Maybe 120fps is enough, maybe you will get headaches after 3 hours. Seeing framewise is simply not the way how the eye\brain system works. It works with a continuous flow of light\information. (Similar to the effects of cameras' flashlights ("red eyes"): flashing is simply not the way how we see). So there are still questions. Maybe you need as much as 4000fps, maybe less, maybe more.

No you're not right.
......Yudda yudda
Well, that's a huge question! But the simple answer has to do with what you were mentioning about looking at stars and noticing that different parts of the eye (looking left to right or on center) would make them more or less visible. That's due to the difference between rods and cones, the two main categories of 'sensors'
Hey, I dug out another one of my references, you'd probably like reading this, because it's a straight-talking awesome introduction to how the eye and color vision work

and between 120 to 200 frames on an individual regional sub-range basis
