Cum oprește anestezia generală conștiința din creier

Over 350 million surgeries are performed annually under general anesthesia, yet the exact mechanisms of how anesthetics induce unconsciousness remain unclear. Recent research is shedding light on brain functions and consciousness origins. Various anesthetics disrupt communication between nerve cells, leading to reduced brain activity. The thalamus appears to be a key region affected first, while some patients may experience a state of awareness during surgery, known as accidental awareness. Studies suggest that general anesthesia alters brain connectivity, making individual brain patterns less unique and more similar to those of other primates, indicating that consciousness arises from a network of brain regions rather than a single area.
