Have you ever wondered what happens when we die? This article delves into the fascinating world of near-death experiences (NDEs), exploring new scientific insights. Discover how a groundbreaking model is beginning to explain the complex neurophysiological processes behind these profound and often life-altering human events.
The Science Behind the Veil: A New Model Explains Near-Death Experiences

The enigmatic experiences reported during near-death events are now under a new scientific lens, offering potential explanations for these profound phenomena.
Decoding the Mystery of EMIs
Visions of light, the sensation of floating, encounters wiht deceased loved ones – these are hallmarks of Near-Death Experiences (EMIs). Are they glimpses beyond mortality, or simply the product of a brain in crisis? A groundbreaking study published in Nature Reviews Neurology proposes a new model, Neptune,
to illuminate the origins of these experiences and their connection to the brain under extreme duress.
What Constitutes a Near-Death Experience?
EMIs typically occur during life-threatening situations such as cardiac arrest, severe accidents, or anesthesia. Surprisingly, they can also arise in less critical contexts, including syncope, meditation, or even orgasm.
These altered states of consciousness transcend age and gender, sharing common characteristics:
- A sense of being outside one’s body.
- Overwhelming feelings of peace.
- The sensation of one’s life flashing before their eyes.
Despite the perilous circumstances, EMIs are frequently enough reported as positive experiences.
the Neptune Model: A Scientific Framework
Researchers suggest that EMIs result from a complex interplay of psychological and neurophysiological factors. We now have enough data to offer a coherent framework explaining the EMI,
states Charlotte Martial, the lead author of the study.
The Neptune model (Neurophysiological Evolutionary Psychological Theory Understanding Near-death Experience), developed by the Coma Science Group, posits that EMIs are triggered by a cascade of neurophysiological and psychological responses to a crisis.
Biological Perspective
Oxygen deprivation in the brain might potentially be a key factor. This hypoxia can disrupt blood flow, alter neural activity, and stimulate brain regions associated with perception and memory, contributing to the immersive and intense nature of EMIs.
Psychological Perspective
Individual susceptibility to EMIs may vary based on pre-existing cognitive traits. Some individuals may possess a greater capacity to detach from their bodies and reality when facing extreme stress.
A Protective Mechanism?
Could EMIs be a survival mechanism, enabling the brain to cope with extreme situations by inducing a state of calm and detachment? The release of serotonin and dopamine, neurotransmitters crucial in activating receptors linked to hallucinations and feelings of well-being, may play a pivotal role.
The Broader Implications
As Pauline Fritz, co-author of the study, emphasizes, The EMIs allow to explore the border between consciousness and unconsciousness, and to learn more about the brain mechanisms involved in this intense experiences.
Beyond the scientific realm, this research can inform better support systems for individuals who have experienced EMIs, acknowledging the frequently enough profound psychological impact. Approximately 10 to 15% of accounts report negative aftereffects, such as anxiety or feelings of isolation. These experiences,perceived as extraordinary,may be suppressed,leading to an underestimation of their true impact.
