Consciousness: Where does consciousness come from?, new paper asks

In this preprint from PLOS, we are informed that "Consciousness arises as an emergent property of the human mind." Not "Consciousness arises as an emergent property of the human brain." The authors have an interesting theory you can read there:

The present work suggests that, rather than hoping for a putative unique marker - the neural correlate of consciousness - a more mature view of conscious processing should consider that it relates to a brain-scale distributed pattern of coherent brain activation," explained neuroscientist Lionel Naccache, one of the authors of the paper.
In other words, there isn't a neurological equivalent of a light switch that wwe turn on when we wake up in the morning.

It's intersting, though, how often that illusion creeps into our language, as in "He saw the light at last about Dora"or "He was out like a light."
