Summary
During sleep, meditation, and psychedelic experiences, a key brain region called the precuneus shows reduced activity patterns. Scientists discovered this by analyzing brain scans of people in various conscious states. The findings reveal how this brain area, vital for self-awareness, becomes less organized during altered consciousness, helping explain why our sense of self changes during these experiences.
