I think the likely explanation is consciousness facilitate a different kind of feed back complexity than other types of information processing in the brain.
Regarding the issue of whether there are specific region(s) of the brain that can be tied to consciousness, indications from disabling of specific regions of the brain by stroke suggest there are. One such indicative stroke symptom is blind sight. Here a stroke deprives the victim of the ability to see. The victim reports total loss oh any sense of sight, even the capacity to perceive light and dark. Yet if a ball is tossed to them without warning, they can capture is in midair. If they are told to navigate a maze, they can do it without touch.
Test show these stroke victims lost conscious perception of sight so completely they will not even voluntarily hazard a guess of what shape is an object before their eyes. Yet if asked to select from a range of choices of what shape, they select 100% accurately over large number of tried. It is as if disability of specific parts of the cortex deprived them of the ability to consciously know the fact that they know something through their senses.
