Detection of rhythmic brain waves suggestive of near-death experiences. Around 20% of people who survive cardiopulmonary resuscitation (CPR) after cardiac arrest may describe lucid experiences of death that occurred while they were seemingly unconscious and on the brink of death. This is according
A new study shows that around one in five people who survive cardiopulmonary resuscitation after cardiac arrest describe lucid experiences of death that occurred while they were seemingly unconscious and on the brink of deathAround 20% of people who survive cardiopulmonary resuscitation after cardiac arrest may describe lucid experiences of death that occurred while they were seemingly unconscious and on the brink of death.
Tests for hidden brain activity were also included in the research. A key finding was the discovery of spikes of brain activity, including so-called gamma, delta, theta, alpha, and beta waves up to an hour into CPR. Some of these brain waves normally occur when people are conscious and performing higher mental functions, including thinking, memory retrieval, and conscious perception.
“These lucid experiences cannot be considered a trick of a disordered or dying brain, but rather a unique human experience that emerges on the brink of death,” says Parnia. As the brain is shutting down, many of its natural braking systems are released. Known as disinhibition, this provides access to the depths of a person’s consciousness, including stored memories, thoughts from early childhood to death, and other aspects of reality.
Some 25 hospitals in the U.S. and U.K. participated in the study, called AWARE II. Only hospitalized patients were enrolled to standardize the CPR and resuscitation methods used after cardiac arrest, as well as the recordings made of brain activity. Additional testimonies from 126 community survivors of cardiac arrest with self-reported memories were also examined in this study to provide a greater understanding of the themes related to the recalled experience of death.
