So you have a research subject and you stick a pin in his brain and that makes him, I don't know, forget the alphabet. You say that contributes to the theory that consciousness is generated by the brain.
Two objections.
1) I already knew you could stick a pin in his eye and he would probably fail to recall the alphabet for several minutes. What I am getting at is that the fact that human consciousness is "heavily invested" in the material universe is bleeding obvious from the get-go. What does recent knowledge about the brain add to this? There is a heluva lot of functionality there, sure. There is a serious nexus of sensation, communication, and computation there, sure. But the above-referenced, Fundamental Question of Consciousness (TM), remains untouched.
2) How do you know your subject (the one with the pin in his brain) is truly conscious? Yes, I am talking about the possibility of a p-zombie[0]. You might want to say, "All reasonable people can here assume that the subject is a truly conscious being." And indeed I agree we can generally, in life, make such assumptions. However, you are hoping for scientific understanding of the nature of true consciousness, so you bloody-well hope for a scientific method to verify a truly conscious being. Otherwise it's like hoping to have the periodic table before you can test whether a material is gold or lead. However, there can be no such hope for a future method of verification, because presently there is not even any observation of the very thing to be verified! This would be like expecting someone who, I don't know, perhaps grew up imprisoned in a cave to develop a model of the solar system.
