What happens to the brain when consciousness goes offline? Scientists uncover how disrupted brain communication can alter awareness, memory and our sense of self

General anaesthesia disrupts brain communication, altering how different regions coordinate their activity. Researchers observe reduced long-range connections and altered functional connectivity during unconsciousness. The thalamus appears to be one of the first brain areas to become less active. Individual brain patterns become less distinct under anaesthesia, offering new insights. This research provides a unique window into the mystery of consciousness.
