Local field potential changes during euthanasia may parallel with near death experience.
Scientific reports – April 03, 2025
Summary
A rebound spike in brain activity may shed light on near-death experiences. In a study involving 40 rats, significant changes were observed in local field potential (LFP) across five frequency bands during euthanasia. Freely-moving rats displayed a surge in LFP three minutes after CO2 initiation, while anesthetized rats showed a general decline in activity. The findings suggest that the brain’s final bursts of activity could correlate with out-of-body experiences reported by humans, challenging perceptions about the dying brain's capabilities at life's end.
