Description

Awareness fades under anesthesia, in sleep, and in coma-like disorders. The thalamus, the brain's relay hub, is suspected of conducting the change. Fa Lu and co-authors pool brain scans across two anesthetic drugs, two depths of disorder, and natural sleep stages. They track how thalamic sub-regions connect to the cortex, and how their local activity fluctuates.

Five nuclei changed with state in every condition, the higher-order ones most consistently. Disorders of consciousness showed the widest disconnections, while sleep leaned on specific relay nuclei. The link between local activity and connectivity shifted with awareness, sketching a thalamic score that future therapies might learn to play.
