On no problem. I was unclear. Some things are difficult to explain. I hadn't heard of the rats and monkeys.

I just read the rats/monkey thing. Interesting.
I would point out that the brain does many things. Control body parts is one thing. Cognition is something else. Controlling the body is fairly well understood. So is remote control from outside sources.

: side note: imagine being 'wired into and eagle's eyes, being able to see everything that the eagle sees. Or better yet to be wired into the eyes of a 'fly on the wall'. Seems possible.

Augmenting cognition, on the other hand , is something else entirely. Cognition is the 'emergent property' that I was referring to. It's NOT presupposed by 'controlling the body'. It's currently a mystery as to how it even happens.
