Is recursive introspection like the infinite regression of two mirrors facing each other?

I can't speak for you, and your consciousness, but I can emphatically say that I don't have any awareness, in my own head, of different parts of my brain doing or thinking different things; but nor do I have any consciousness of the instructions I send to my hand when I want to lift it off the desk. I consciously decide to lift it, but I do not see, feel or otherwise sense the actual impulse that causes the movement. However, I can understand what happens, and it is possible to explain in minute molecular detail what happens. Likewise, brain-imaging techniques have allowed an understanding of non-motor nerve function inside the cranium. To gain an understanding of this you (or I) would need somehow to visualise the 3 dimensional structure of the brain. I don't mean that you (or I) should research it(!), but that we present our minds with some sort of chart that allows cognition.

If we take a simple 3d object, like a football, you would quickly be able to visualise the complete structure in your mind. If I chose an apple, you would have no problem creating a 3d image of that. If I took a fruit that you had never seen and described it, you may be able to visualise it; but if you failed to do so, I could draw diagrams to help you. On opening it up, you'd still have some surprises. Say I took a whole city, with everything in it and rolled it into a ball - it's going to be very hard for me to explain where everything is, and very hard for you to visualise where everything is. That's just a starting point compared to the brain!
