A study published in Nature reveals that parts of the brain remain active and can process language even under anaesthesia. Researchers found that neural circuits respond to stimuli without consciousness, indicating that the brain is more capable during unconsciousness than previously believed. The study involved seven patients undergoing epilepsy surgery, where data was collected on how their brains processed sounds and language. Results showed a significant response to auditory stimuli, suggesting the brain registers sounds even when unconscious. Further research is needed to explore brain activity under anaesthesia and its similarities to sleep.
