“Consciousness can be defined as wakefulness, awareness, and self-awareness. Brain imaging studies of people in different levels of consciousness (sleep, vegetative state, coma, neuropsychological disorders) can help reveal the neural correlates of consciousness. The strongest neural correlates of consciousness include attention networks, the default mode network, and the claustrum. The claustrum coordinates the transition between attention networks and the default mode network. Complex functions such as consciousness and attention require coordination amongst multiple brain areas. The location and size of these functional networks can differ between individuals…”
