I think all those "switches" and spaghetti stuff is the main substance behind decision making and thought. The brain wouldn't be much good without it. What's slowing everything down is stupid people who don't want to learn anything, get educated, or be challenged.
Good article!
The brain is the inhibitor of thought in the same way that the body is the inhibitor of motion. Light and energy transcend human limitations, and as the driving force behind any human activity, they take on certain limitations when confined to the human vessel.
Once that which is the living being is removed, the body is a lifeless lump of clay. What then is tissue and organic mass but the vehicle that requires the power to function, without which that power is unburdened.
The brain is indeed a wonderous thing. It facilitates thought for the human body, by inhibiting the very thing that drives it.
