Life after death declared 'credible,' as new study challenges idea that consciousness ends when your brain shuts down

Your mind could live on after death, even when your brain stops working, a researcher has suggested. Finland-based researcher Pekka Rechardt based the idea on accounts of cardiac arrest survivors who recalled vivid experiences that an earlier review placed during periods of severely suppressed or undetectable electrical brain activity.Rechardt reexamined a 2025 review of near-death research by a team of international researchers, who reported that electrical activity in the cortex, the brain’s outer layer, can disappear within 10 to 30 seconds of cardiac arrest.The authors of that review, published in the peer-reviewed journal International Review of Psychiatry, argued that some near-death experiences occur during this suppressed period, when an electroencephalogram, or EEG, shows a flat recording.Rechardt treated those accounts as evidence supporting the possibility that consciousness does not depend entirely on brain activity.For Rechardt, the puzzle is that these experiences retained three basic ingredients of awareness: a sense of being present, vivid sensations and the ability to experience events as a coherent whole.He argued that if those ingredients can persist without the brain activity normally associated with consciousness, the destruction of the brain might not necessarily destroy the mind.‘This empirical consideration supports life after death being a credible option,’ he wrote. A new paper argues that vivid near-death experiences support the possibility that consciousness exists beyond the brain and could survive deathPublished in the Journal of Consciousness Studies, the paper developed an explanation of consciousness that Rechardt proposed in 2023.The earlier review, by Bruno Angeli-Faez, Bruce Greyson and Pim van Lommel, also reported that alpha and beta brain rhythms, which it describes as critical for consciousness, disappear within about 6.5 seconds of cardiac arrest.Rechardt’s own explanation starts from the assumption that consciousness cannot be reduced to brain activity. He then asked how experiences fit together, even in ordinary life.The paper uses the example of someone walking along a sunny beach, enjoying the scenery and warmth while thinking about philosophical questions.These sensations and thoughts involve different parts of the brain, and signals take time to travel between them. Yet the person experiences them together, as one unfolding scene.Rechardt argues that explaining this unified perspective requires more than identifying the individual brain processes involved.His proposed answer is an additional spatial dimension beyond familiar length, width and height, from which information associated with different brain regions could be experienced together.He illustrated the principle by considering how someone looking down at a flat drawing can see its separate parts together from a position above the page. Near-death experiences, the researcher wrote, may offer ‘a glimpse of what awaits her or him’ when the bodily functions that sustain human life have endedExtending that analogy, he proposed that the three-dimensional brain could be associated with a conscious perspective in a fourth spatial dimension.Another part of his argument concerned the feeling of being present in the ‘Now.’ A near-death experience can include memories or unfamiliar scenes, but the person still experiences them as happening within a present moment.Rechardt argued that describing physical events in space and time does not fully explain that personal sense of presence.He makes a similar distinction between detecting a brain response to a color and explaining what seeing that color actually feels like.These questions form part of the ‘hard problem’ of consciousness: why physical processes are accompanied by subjective experiences.For Rechardt, the persistence of these familiar features in near-death accounts is a reason to consider a framework for awareness beyond the brain. However, gaps in an explanation do not establish that his alternative is correct.He applied his dimensional analogy to death by noting that destroying a painting does not destroy the person looking at it.In his proposed scenario, death could similarly end the connection between the brain and consciousness without destroying the framework in which experience occurs.Awareness could then continue without receiving information through the body’s senses, he suggested.That possibility depends on the framework existing independently of the brain, rather than being created and maintained by it.Near-death experiences, he wrote, may offer ‘a glimpse of what awaits her or him’ when the bodily functions that sustain human life have ended.
