Most scholars consider consciousness to have two components: wakefulness and awareness. Wakefulness is fairly easy to define and measure experimentally, through EEG, because the pattern of activity shown by EEG is different in brains of awake subjects, compared to subjects who are asleep.

Awareness, on the other hand, is neither easy to assess, nor to define – what exactly does it mean to be “aware” of your surroundings? Are there different stages or levels of awareness? Are there any other more accurate and objective ways of assessing awareness other than through questionnaires filled in by subjects, which is how it is often assessed?
But the most crucial and interesting question yet to be answered is the following: is consciousness generated through the orchestrated activation of multiple brain areas, or is there one particular area responsible for it?
