I think there is a definite distinction between perceptions and models. For example, we don't consciously perceive the edge and motion detection of our vision system but instead the aggregate interpretation of modelling those perceptions. Similarly we don't seem to be conscious of some internal organs, but conscious of others under different circumstances. Usually we aren't conscious of our breath but by focusing we can both raise conscious awareness and control of it. So it seems like we have a "consciousness" module in the brain that can be directed and connected to different other parts of our nervous system, but not all, in order to "do the perceiving". With practice it seems possible to become conscious of more autonomous parts of the body, but not all. And still the question remains of how the brain produces the conscious experience and expands or contracts it, while not being fully conscious of the whole brain or of its own operation (in which case we would understand consciousness much better). Is it the chemical activity? The electrical? A combination? Is it in the energy transfers between matter or in the relationships that get established?
