D'autre part, ce qui me gene dans l'étude Aware, c'est qu'ils disent que le cerveau reste conscient 3 minutes après la mort. Or, avoir des hallucinations, ce n'est pas etre conscient à proprement parler. Si ? Et si le cerveau était en conscience réelle comme ils le disent, il me semble que la personne saurait alors qu'elle est morte.
les morts ne se lèvent pas de leurs lits pour causer EMI.

Ce que je veux dire c'et que la personne qui a eu un accident et vit une emi, si elle est en état de conscience, pourquoi ne réalise t elle pas qu'elle est momentanément cliniquement morte, une fois revenue ou meme pendant son emi?
certains témoins en parlent, et disent avoir été ''conscient'' d'être cliniquement mort (mort).
Abstract
The brain is assumed to be hypoactive during cardiac arrest. However, the neurophysiological state of the brain immediately following cardiac arrest has not been systematically investigated. In this study, we performed continuous electroencephalography in rats undergoing experimental cardiac arrest and analyzed changes in power density, coherence, directed connectivity, and cross-frequency coupling. We identified a transient surge of synchronous gamma oscillations that occurred within the first 30 s after cardiac arrest and preceded isoelectric electroencephalogram. Gamma oscillations during cardiac arrest were global and highly coherent; moreover, this frequency band exhibited a striking increase in anterior–posterior-directed connectivity and tight phase-coupling to both theta and alpha waves. High-frequency neurophysiological activity in the near-death state exceeded levels found during the conscious waking state. These data demonstrate that the mammalian brain can, albeit paradoxically, generate neural correlates of heightened conscious processing at near-death.

conclusions
CA survivors experience a broad range of memories following CPR including fearful and persecutory
experiences as well as aware-ness. While explicit recall of VA is rare, it is unclear whether these
experiences contribute to later PTSD. Studies are also needed to delineate the role of explicit
and implicit memory following CA and the impact of this phenomenon on the occurrence
of PTSD and other life adjustments among CA survivors.

ça ne veut absolument rien dire, mais je trouve que c’est assez dans le ton.
