It is worth noting that an international research team studying the memories of patients who recovered after clinical death has put forward a complete theory called "Neptune," and this theory provides a natural scientific explanation for the psychological emotions close to death.
Grayson and Behlevanova analyzed the various factors on which the authors of the "Neptune" theory based their arguments, including the effect of drugs, changes in blood composition in the brain, hallucinations, as well as "tunnel vision" occurring in the dying brain, or "electric shots" in it.
They emphasized that "there is a substantial body of empirical data, both from near-death experiences and related phenomena," that goes beyond physiological or "material" explanations, as they put it. Some patients recall, after clinical death, that all their senses were involved in their emotional experiences, including their sense of smell, and that in this state they encountered close friends and family members, as well as people they had never met before.
The scientists said that physical models cannot adequately explain these common experiences, as clear and accurate conscious perception occurs in the absence of normal brain activity and even in the presence of severe brain dysfunction.
The two scientists reminded everyone that "the question of consciousness and its connection to the brain remains one of the greatest mysteries in science," objecting to the theory that "consciousness results from brain activity and can therefore be fully explained by it."
