Differences in brain activity between connected and disconnected states of consciousness studied with positron emission tomography imaging. Activity of the thalamus, anterior (ACC) and posterior cingulate cortices (PCC), and bilateral angular gyri (AG) show the most consistent associations with the state of consciousness (A = general anesthesia, B = sleep). The same brain structures, which are deactivated when the state of consciousness changes to disconnected in general anesthesia or natural sleep (cool colors in the left columns), are reactivated when regaining a connected state upon emergence from anesthesia (warm colors in the right columns).

The loss and return of consciousness is linked to the same core brain network for both sleep and anesthesia. Differences in brain activity between connected...
