Scientists studying near-death brain activity found that for several minutes after clinical death, brain cells can remain active. During this time, the brain may replay vivid memories and emotional experiences. Researchers from the University of Michigan observed high-frequency waves similar to those seen during dreaming and memory recall. This activity suggests that consciousness might briefly persist as the brain replays key life moments. The finding adds new insight into how the human mind processes the end of life and challenges our understanding of awareness after death.
