Rats! & NDE: SQUEAK

D8133A5D-40AA-4536-9B15-29FCFF1514BC.jpgNDE have been used as proof of the existence of souls in a large set of stupid arguments.
Following this trend, it seems that prophet Sir Terry Pratchett revealed that rats have souls, managed by the DEATH of Rats of course, in his novels.
Now scientific evidence come to support either:

  • the existence of rats’ souls, or
  • the non-supernatural, quite materialistic, explanation of NDE.

Surge of neurophysiological coherence and connectivity in the dying brain

PNAS 2013 ; published ahead of print August 12, 2013, doi:10.1073/pnas.1308285110

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.

    Arrête de citer Pratchett à la légère !

    Si jamais Jean Staune tombe dessus il va sûrement écrire « les anals du triste monde » sans payer les copyrights… (biz en passant :)).

    Nox!
    Quel plaisir!
    Le père Staune parasiter les écrits de quelqu’un d’autre ? Ca serait bien dans la continuité de son oeuvre, c’est sûr ;-)
    Bises.
