You may have wondered how we can prove the brain sends information back in time. While a patient is laying on a table with his brain exposed the doctor would touch a electro probe to the region of the brain that feels the little finger. The reponse was measured at taking almost a second. When the probe touched the actual little finger however it was virtually simultaneous. No elapsed response time vs. a second or sometimes longer. The brain had information before it should have been able to register it and respond.
When it comes to baseball the same thing is true. THere simply isn;t enough time to respond to hitting fast ball. Its done with anticipation.

I have a wierder example of the brain anticipating things that can be experimentally repeated by anyone... stay tuned.
