The Fascinating Brain Activity During the Final Moments of Life.

Scientists have detected a surge in brain activity in the area associated with consciousness in two comatose patients in their final moments, even after their hearts stopped beating. The findings could help explain why many report vivid visions during near-death experiences. However, the sample size is incredibly small, which makes drawing any definitive conclusions impossible. The surge in gamma waves was concentrated in a part of the brain associated with dreaming and hallucinations reported by epilepsy patients.
