The brain still active following cardiac arrest
Thus, two of the patients showed an increase in heart rate as well as an increase in gamma wave activity, “considered to be the most rapid brain activity associated with consciousness”, explain the authors.
In addition, activity was detected in the so-called “hot zone of the neural correlates of consciousness in the brain”, at the junction between the temporal, parietal and occipital lobes at the back of the brain. “This area is correlated with dreams, visual hallucinations in epilepsy and altered states of consciousness,” the researchers continue.
On the other hand, the two other patients did not display the same symptoms when the respiratory assistance was withdrawn. The authors therefore want to remain cautious regarding these manifestations of consciousness during a near-death experience. However, “these observations are definitely exciting and provide a new framework for our understanding of a secret consciousness in dying humans”.
