I don't know that learning more about the brains operation will satisfy people who resist the notion that their consciousness is a property of a physical system. Since it is an emergent property of a complex system, even if we understood the functioning of each independent piece, we would still be left with the question of why all of those pieces in concert have the property of consciousness. While we gather more and more data on the brain, we barely even have a beginning notion of how emergent properties actually work. If we had to take everything we know about atoms and their interactions and explain where phase transitions and states of matter come from, we would be stymied. We know from experimentation that very large groups of many atoms do experience distinct phase transitions. We know every way individual atoms can interact. But bridging that gap from components to being able to predict large-scale complex nonlinear dynamics... we have more proofs of our inability to do such things (with conventional tools) than hints of how we might tackle it.
