I don't see that consciousness is in any way separable from the brain and its electrochemical activity of information representation. Consciousness appears to be an evolved function of sufficiently complex brains....working up the scale from rudimentary perception of the world by light sensitive cells transmitting information to small bundles of interconnected neurons providing a sense of light and shadow and movement to respond to (danger, food, shelter, etc), through to the incredibly complex human brain...each producing a representation of world and self in accordance to what its architecture enables.
When two things are inseparable, like twins who never leave each other's side, the fact is that they are still two things. I'll leave out the rest about pattern recognition because it has to to with cognition and not consciousness (which by now I hope you understand I mean subjective experience).
Actually, cognition is a good way to illustrate why I am interested in this. I don't have any problem saying that cognition is a function of the brain, or even just an activity of the brain. It's very much a 'how' question. Once we understand the process of cognition, we will understand cognition.
The subjective experience of the mind, including perhaps the subjective experience of cognition, is a totally separate
topic, even though it may in reality be
inseparable from whatever the brain is doing--cognition, for instance. I am not asking about how the brain produces consciousness, and I don't disagree that it produces consciousness in its entirety; what I am interested in is the
ontological status of what is being produced.
You used the word 'representation'... a representation is always a point-to-able phenomenon, distinct from the procedure that gave rise to it (and distinct from what is being represented!). We can point to a digital display and identify it as representation of some state of the computer, a scoreboard as a representation of the activity of the opposing teams, a ledger as a representation of monetary transactions. It's always something publicly observable. So, if you're being consistent, you can't really say that consciousness is a representation of the world created by the activity of the brain, but also is
one and the same thing as the activity of the brain as it represents the world. That's like saying a digital display is both a representation of the computer's internal activity and simultaneously no more than that exact internal activity. Representations are independent from what they represent, even if they can't be separated from it.
None of this goes against what is known about brain agency. I would venture to say the two topics are scarcely related.
