How Anesthesia Blocks Consciousness

Posted by in category: neuroscience

Summary: A new study reveals insights into how general anesthesia affects consciousness and sensory perception.

Using animal models, researchers found that while propofol anesthesia allows sensory information to reach the brain, it disrupts the spread of signals across the cortex. This suggests that consciousness requires synchronized communication throughout the brain, and propofol’s effect of limiting this interconnectivity could explain its role in inducing unconsciousness.
