Timewarp: How your brain creates the fourth dimension | New Scientist
“VanRullen has an alternative explanation. The brain processes different objects within the visual field independently of one another, even if they overlap in space, he suggests. So the RPL may well be taking the “snapshots” of the two moving patterns at separate instances – and possibly at slightly different rates – making it plausible that the illusions could happen independently for each object.
This implies that there is not a single “film roll” in the brain, but many separate streams, each recording a separate piece of information. What’s more, this way of dealing with incoming information may not apply solely to motion perception. Other brain processes, such as object or sound recognition, might also be processed as discrete packets.”
