I would agree that it would be only a theory that brain changes 'produce' consciousness, but I would say that we can say with confidence that changes in our awareness are more tightly synchronized with changes in brain activity than with those of the liver, or any other thing in the universe that we can observe. When we stimulate the brain magnetically, that event correlates directly with subjective experience. I don't think that there is anything else we could stimulate which would cause that.
