Unveiling the Unconscious: Study Reveals Cortical Network Engagement

A recent study conducted by researchers at Massachusetts General Hospital has identified distinct cortical networks that are engaged during different states of unconsciousness, such as sleep and general anesthesia induced by propofol. The study found that during sleep, the brain shows simpler and reduced brain connections, while under anesthesia, changes in prefrontal regions are particularly prominent. These findings suggest that different parts of the brain are involved in different ways during different forms of unconsciousness. The research could contribute to our understanding of consciousness and have implications for therapeutic neuromodulation.
