Tentatively Christian; looking for a reasonable discussion

[The Reality Salesman01]

What consciousness is in the first person perspective and what it is from the third person perspective will give you both what it is, and what it is made of. Just as a pain in my head accounts only for the experience of having a stroke, the third person understanding is a complimentary and necessary account for the entire description of the event being experienced. The moment we discovered that events, details, and our abilities in consciousness are entirely behold unto specific regions in the brain, to me, that was the moment this dualism nonsense became pure conjecture. If there were a separate unidentifiable substance required to generate consciousness, it wasn't very interesting to me if it was only useful if every single region of the brain was required to function perfectly in order for it to be recognized as anything coherent. That idea seems either false, or uninteresting.
