Hi Pat! My first thought has to do with how the CNS screens information. Remember, the problem with having too many connections creates a more primary problem of what needs to be screened out. By providing input via movement (vestibular) or deep pressure (proprioception - awareness of our body in space), the CNS screen called the Reticular Activating System (RAS)is stimulated and thus helps inhibits sensory input or overload. Paradoxically, it is the inhibitory centers of the brain that are not working. It's what happens to us when we are under extreme stress and we have difficulty keeping information out and subsequently lose our ability to react efficiently. However, most of the time, since our CNS is organized and "integrated", we can decide what needs our attention and react accordingly. I hope this makes sense. Chuck
