“…Cardiac arrest is invariably associated with the loss of external consciousness and sensory responsiveness, which has been interpreted to represent arrested brain function. The extremely low amplitude of scalp EEG, in addition, has been used frequently as evidence for the absolute absence of cortical function during cardiac arrest (22)(23)(24). Contrary to this belief, we show here that mammalian brain is highly activated at near-death.…”

The mechanism by which the healthy heart and brain die rapidly in the absence of oxygen is not well understood. We performed continuous electrocardiography and electroencephalography in rats undergoing experimental asphyxia and analyzed cortical release of core neurotransmitters, changes in brain and heart electrical activity, and brain-heart connectivity. Asphyxia stimulates a robust and sustained increase of functional and effective cortical connectivity, an immediate increase in cortical release of a large set of neurotransmitters, and a delayed activation of corticocardiac functional and effective connectivity that persists until the onset of ventricular fibrillation. Blocking the brain's autonomic outflow significantly delayed terminal ventricular fibrillation and lengthened the duration of detectable cortical activities despite the continued absence of oxygen. These results demonstrate that asphyxia activates a brainstorm, which accelerates premature death of the heart and the brain.asphyxic cardiac arrest | autonomic nervous system | coherence | directed connectivity | near-death experience

“…A inconsciência ocorre rápido demais para que a experiência ocorra até esse momento -11 segundos após uma parada cardíaca, sobrevém o silêncio elétrico e o cérebro está totalmente disfuncional 27 . As experiências são lúcidas e, portanto, não podem ocorrer durante o período de recuperação, que é sempre confusional.…”

ResumoA EQM é um estado alterado de consciência que no ocidente inclui uma experiência emocional e de conteúdo estereotipado. Algumas características da experiência são transculturais e sugerem ou um mecanismo cerebral similar ou acesso a uma realidade transcendente. Características individuais da experiência indicam mais persuasivamente para transcendência que para um simples mecanismo cerebral limitado. Além disso, não há, até agora, nenhuma explicação reducionista que possa dar conta satisfatoriamente de algumas dessas características: o encontro com parentes falecidos, a aparente capacidade visual em cegos durante a EQM, a aparente aquisição de dons psíquicos e espirituais após a EQM, relato de cura ocorrida durante uma EQM e experiências verídicas durante a ressuscitação pós-parada cardíaca. Embora uma mente não local pudesse explicar muita das características das EQM, a não localidade ainda não é aceita pela corrente predominante da neurociência. Somente aquelas teorias baseadas num entendimento mais amplo da mente poderiam explicar totalmente a experiência subjetiva dos que vivenciaram uma EQM.

Fenwick P / AbstractThe NDE is an altered state of consciousness which in the West has stereotyped content and emotional experience. Some features of the experience are transcultural and suggest either a similar brain mechanism or access to a transcendent reality. Individual features of the experience point more persuasively to transcendence than to simple limited brain mechanisms. Moreover there are, so far, no reductionist explanations which can account satisfactorily for some of its features; the meeting of dead relatives, the apparent "sightedness" in the blind during an NDE, the apparent acquisition after an NDE of psychic and spiritual gifts, accounts of healing occurring during an NDE, and of veridical experience during the resuscitation after a cardiac arrest. Although non-local mind would explain many of the NDE features, non locality is not yet accepted by mainstream neuroscience. Only those theories based on a wider understanding of mind could fully explain the subjective experience of the NDEr. Rev Psiq Clín. 2013;40(5):203-7 Keywords: NDE, consciousness, non-local mind, mind sight, psychic gifts. Fenwick P / IntroduçãoFaz mais de 30 anos desde que Raymond Moody publicou sua obra seminal -Life After Life (1975) 1 . Esse livro descreveu as EQM e trouxe-as à atenção dos públicos leigo e médico. Muitos leigos interpretaram essas experiências como prova de uma extensão da consciência para além da morte (embora o Dr. Moody nunca tenha feito essa afirmação diretamente), enquanto a categoria médica sugeria que mudanças químicas no cérebro eram inteiramente responsáveis pelas experiências.Noyes e Slymen 2 , na primeira tentativa de uma análise estatística da EQM, encontraram três fatores gerais subjacentes: hiper-vigilân-cia, com aceleração dos pensamentos e visão e audição...

“…All fermions that have been observed experimentally in the past are in this category. 2 , on the other hand, is what I call "parasite fermion" and the parasite fermion field can be localized around the brane only when it couples to the host fermion field through the fermion coupling. From the lagrangean density one can obtain an equation of motion for such that …”

“…Even if bloodstream in a brain stops, the brain stops its activity, and the brain waves become flat, it is not impossible to regain life unless brain cells perish. In addition, there may be the need to examine mind activity to exist independent of brain activity when we consider the example that a person could mention, after he/she regained his/her consciousness, his/her memory of what had happened in his/her neighborhood, or the feelings that had come up in his/her mind while his/her brain was stopping its activity [1][2][3]. Having said that, however, we cannot think the brain activity and the mind independent of substances which exist irrelatively with each other at all, concerning the example of above-mentioned fMRI.…”

Fermion field in the vicinity of a brane

A mechanism that enables fermions to live outside of but be localized near a brane is proposed based on the field-theoretical framework. Two types of fermion fields are considered: one is localized to the brane through the Yukawa interaction, and another is localized through the fermion interaction. It is shown that, besides the well-localized zero-mode, there exists a light mode continuum of which oscillating components are delocalized. As a consequence it is possible to assume existence of invisible material particles that live outside the brane on which we reside and beleaguer visible particles. A possible extension to the mind-body problem is discussed.
