Here's a link to an interesting article in LiveScience discussing recent research findings about how the eyes and brain track a moving ball.
How Your Brain Tracks Moving Objects | Brain Activity & Vision Science | LiveScience
Brief excerpt follows (my bold added for emphasis).
"When human eyes see an object, it takes one-tenth of a second for the brain to process that information, said Gerrit Maus, a postdoctoral fellow in psychology at UC Berkeley, and lead author of the new study detailed today (May 8) in the journal Neuron. So how does the brain compensate for the slight delay? "The brain does not think the object is in the position where the eye tells us it [that it] is," Maus told LiveScience. "The object is shifted forward in the direction that it's moving, so we're actually predicting where things are going to be." This means the brain perceives moving objects to be farther along in their trajectory than what a person actually sees with their eyes, he explained.
....... the V5 region (of the brain) is involved in tracking moving objects, pushing them along in their trajectories so that a person, such as a baseball player hoping to hit a fastball, is not constantly processing out-of-date information, the researchers said. "What we perceive doesn't necessarily have that much to do with the real world, but it is what we need to know to interact with the real world," Maus said."
PS No hint in regard to whether or not the researchers concluded that a rise ball really rises!!!
