1) The document discusses a prospective study on near-death experiences (NDEs) in 344 cardiac arrest survivors in the Netherlands. The study found that 18% reported some recollection of the period of unconsciousness during cardiac arrest, with 12% reporting a core NDE experience. 2) The study could not find any physiological, pharmacological, psychological, or demographic factors that explained why some patients experienced consciousness during clinical death while most did not. 3) The findings challenge assumptions that consciousness is localized in the brain, as complex experiences were reported when brain function had ceased during cardiac arrest. The results push the boundaries of understanding about consciousness and its relationship to the brain.
