In Chapter 12 Penfield makes the following statements:
By taking thought, the mind considers the future and gives short-term direction to the sensory-motor automatic mechanism. But the mind, I surmise, can give direction only through the mind’s brain-mechanism. It is all very much like programming a private computer. The program comes to an electrical computer from without. The same is true of each biological computer. Purpose comes to it from outside its own mechanism. This suggest that the mind must have a supply of energy available to it for independent action.
I discuss Penfield’s proposed “energy” in my two blogs posted above entitled, “Waves in Our Brains,” Parts One and Two. I discuss the suggestion he made above extensively in my two books. I update the content presented in my books in specific blogs on this website.
