Prior hypotheses as to the etiology of near-death experiences (NDEs) have been limited to psychiatric explanations or brief discussions of endorphins as causative agents. We present a neurophysiological explanation for NDEs based on their similarities with lysergic acid-, ketamine-, and hypercapnia-induced hallucinations. We believe the core NDE is genetically imprinted and triggered by serotonergic mechanisms. 
Semiology and Mechanisms of Near-Death Experiences
Recent prospective studies confirm that NDEs reflect a spectrum of highly distinctive memories which are associated with negative or positive emotions and can be influenced by the nature of the causal event, but the temporal sequence with which these images unfold is variable.
Near-Death Experiences and the Theory of the Extraneuronal Hyperspace
It is possible and desirable to supplement the traditional neurological and metaphysical explanatory models of the near-death experience (NDE) with yet a third type of explanatory model that links

The inclusion of this new diagnostic category in the DSM-IV permits differentiation of NDEs and similar experiences from mental disorders and may lead to research into more effective treatment strategies.

Near-death experiences are important to physicians not only because they may occur to patients while under the authors' care, but because they often lead to profound aftereffects that may affect health and response to medical treatments.
DMT Models the Near-Death Experience
A significant overlap in nearly all of the NDE phenomenological features is found when comparing DMT-induced NDEs with a matched group of ‘actual’ NDE experiencers, and a striking similarity between these states that warrants further investigation is revealed.
“Reality” of near-death-experience memories: evidence from a psychodynamic and electrophysiological integrated study
The findings suggest that, at a phenomenological level, NDE memories cannot be considered equivalent to imagined memories, and at a neural level,NDE memories are stored as episodic memories of events experienced in a peculiar state of consciousness.
Near-Death Experiences and the Possibility of Disembodied Consciousness Challenges to Prevailing Neurobiological and Psychosocial Theories
Claims from those having near-death experiences (NDEs), as well as those sympathetic to such claims, challenge the prevailing assumption that consciousness is dependent on a functioning brain. Extant


The psychodynamics of near-death experiences.

A number of psychological mechanisms are discussed, which overdetermine the prototypical NDE, and objections to psychological interpretations of the phenomenon are considered.

The illusions and hallucinations experienced by two miners trapped together for six days in a situation of marked reduction of sensory input are described. Their mental productions were chiefly
The phenomenology of near-death experiences.
The authors studied retrospectively 78 reports of "near-death experiences using subjects narratives and questionnaires, interviews, and medical records", finding the influence of cultural and psychological factors, sensory deprivation, and reflex adaptive responses to stress explain some but not all of the features of near- death experiences.
Near-death experiences in a pediatric population. A preliminary report.
Four of seven children who survived cardiopulmonary arrests or coma associated with trauma, drownings, or hyperosmolar states reported near-death experiences, and children report near- death experiences similar to ones previously described in adults.
Childhood near-death experiences.
A neurophysiologic hypothesis as to the cause of NDEs is presented and it is suggested that a core NDE, triggered by the process of dying or resuscitation efforts, may be a natural developmental experience.

Ketamine and the conscious mind
The introduction first of phencyclidine (Sernyl), and then of its derivative ketamine (CI-581, Ketalar), has heralded a new phase in anaesthesia, and its value in certain special situations is well recognised.

The effects of nalorphine on behaviour are felt to be so undesirable as to preclude its use as a major analgesic even if it is shown to be such a drug.
