During euthanasia, rats that were freely moving showed a brief surge in brain activity across five frequency bands in four brain regions about three minutes after carbon dioxide began, followed by a general decline. Anesthetized rats showed only a steady decline with little rebound. The rebound surge in the freely-moving group may help explain the vivid experiences reported in human near-death experiences, suggesting such phenomena could emerge from the brain's final bursts of activity.
