Experience Leads to the Growth of New Brain Cells (click for more)
"Functional neurogenesis means that new brain cells grow deep within an area of the brain called the hippocampus, and then migrate to specific areas of the brain where they are needed. These new brain cells then permit new functions or repair damaged functions in the brain."
I've used this quote before, http://thoughtfulveg.blogspot.com/2012/03/new-brain.html It explains what happened and is happening to me. It takes "miracle" off me and puts it back on the brain. I'd say it's another "wondrous property."
I would think those new cells that are created are blank and need to be programmed. You program them with therapy and exercise. Not once, but over and over for a while. Do nothing and you see nothing. I've been exercising for years (therapy exercises not cardio-vascular exercises). There has been improvement for years.
So you gotta do somethin' if you want somethin'.
