Es gibt zwar viele Fallgeschichten von out of body experience und Nahtoderfahrung. Angeblich soll der Körper auch 21 Gramm leichter werden aber verlässliche Daten gibt es keine. Eine neue Arbeit beschreibt aber nun die Hirnaktivität eines 87jährigen der einen Herzstillstand unter laufendem EEG erleidet.
Cross-frequency coupling revealed modulation of left-hemispheric gamma activity by alpha and theta rhythms across all windows, even after cessation of cerebral blood flow. The strongest coupling is observed for narrow- and broad-band gamma activity by the alpha waves during left-sided suppression and after cardiac arrest.
Die Vorerkrankung schränkt die Aussagekraft zwar ein, aber die Autoren schreiben
The alpha band is thought to critically interfere in cognitive processes by inhibiting networks that are irrelevant or disruptive … Given that cross-coupling between alpha and gamma activity is involved in cognitive processes and memory recall in healthy subjects, it is intriguing to speculate that such activity could support a last “recall of life” that may take place in the near-death state.
