Imaging of the human brain reveals constellations of activity associated with conscious and unconscious states

The brains of people in vegetative, partially conscious, or fully conscious states have differing profiles of activity as revealed by functional magnetic resonance imaging (fMRI), according to a report in Science Advances. The results of the study indicate that, compared with patients lacking consciousness, the brains of healthy individuals exhibit highly dynamic and complex connectivity.

This new study provides a substantial advance in characterizing the ‘fingerprints’ of consciousness in the brain, It opens new doors to determining conscious states—or their absence—in a range of different conditions.
