I'm referring to consciousness as awareness, subjectivity, the ability to experience or to feel, not wakefulness, executive control, nor the sense of selfhood, since they all (except, arguably, executive control) depend on awareness. They're poorly defined because our culture has not thought a lot about this, IMO. Hindu philosophy has a much better conceptualization (like Inuit culture has a better conceptualization of the varying states of snow).
