Signature of consciousness captured in brain scans – life – 12 November 2009 – New Scientist.

A telltale signature of consciousness has been detected that takes us a step closer to disentangling the brain activity underlying conscious and unconscious brain processes.

It turns out that there is a similar pattern of neural activity each time we become conscious of the same picture, but not if we process information from the image unconsciously. These contrasting patterns of activity can now be detected via brain scans, and could one day help determine if patients with brain damage are conscious. They might even be used to probe consciousness in animals.

“It’s very exciting work,” says neuroscientist Raphaël Gaillard of the University of Cambridge, who was not involved in the work. “The use of a reproducibility measure to disentangle conscious and non-conscious processes is genuinely new.” Gaillard has previously shown that coordinated activity across the entire brain is one of the signatures of consciousness .
