I very much doubt it. Brain research indicates that virtually all brain function is carried out without involving consciousness.
For example, a famous brain experiment back in 2008, based on a detectable brain change representing a particular kind of decision, demonstrated that observers knew the subject's decision up to seven seconds before the subject did.
Or take a more local example. Where are these words I'm typing in the quarter-second before I type them? Certainly not in my conscious mind. And where are the words you speak in the quarter-second before you speak them? Again, certainly not in your conscious mind. (That's the basis of Auden's notable remark, "How do I know what I think till I hear what I say".)
Or how does your brain make choices? Sometimes with exact reasoning and all your books or brochures open around you, but far far more often by a process you never notice although you feel you own the decision made. The basic decision-making processes are well-studied and described, and aren't done consciously ─ you never know beforehand just why you feel like strawberry today when chocolate's always been your favorite.
The more we learn, the more we think consciousness is an incident of thought, not central to it.
