They say these encounters are typically seen as hallucinations or illusions because research is so finite on the taboo subjects. In the U.K., doctors looked at out of body experiences (OBEs) and near-death experiences, too.

Tweet This Click to share quote on Twitter: "I could individually go into each person and I could feel the pain that they had in their life … I was allowed to see that part of them and feel for myself what they felt," one volunteer said. I was not in time/space so this question also feels impossible to answer,” one respondent said, according to the U.K.’s Telegraph newspaper. “There is not one linear progression, there is lack of time limits … it was like being there for centuries.

The group admitted, in what felt like final moments, time was no longer a tangible measurement. This suggests that a representation of life events as a continuum exists in the cognitive system, and may be further expressed in extreme conditions of psychological and physiological stress,” the authors wrote.Īfter listening to the interviews, the scientists pulled together a questionnaire to send to 264 other people who also went through near-death experiences. 22 in Frontiers in Aging Neuroscience.“Re-experiencing one’s own life events, so-called LRE, is a phenomenon with well-defined characteristics, and its subcomponents may also be evidenced in healthy people. ![]() I think if we know that there is something happening in their brain, that they are remembering nice moments, we can tell these families and it builds a feeling of warmth that in that moment when they are falling, this can help a little bit to catch them," Zemmar offered. Right now, we don't know anything about what happens to their loved one’s brain when they're dying. "On the spiritual side, I think it is somewhat calming," the researcher and neurosurgeon added, describing the moments he often has with families with their loved one passes away. Zemmar suggested that maybe it’s our brain letting us "have a replay of life in the last seconds when we die." On the metaphysical side, the study author said the observed brain activity patterns that occur when we have memory recall, dreaming and meditative states are "intriguing to speculate" about. ![]() Pictured are CT scans of the patient, whose identity was not disclosed. The study author said the findings "challenge our understanding of when exactly life ends," pondering if it’s when the heart stops beating - or when the brain stops functioning. "Through generating brain oscillations involved in memory retrieval, the brain may be playing a last recall of important life events just before we die, similar to the ones reported in near-death experiences," Zemmar suggested. These brain waves signal everything from what we experience when we’re asleep to the activity during a state of alertness, according to the Sinha Clinic, an Illinois-based clinic offering neuropsychiatric treatment. Changes were also observed in others such as delta, theta, alpha, and beta oscillations. In the new research, changes were observed in the so-called gamma oscillations. ![]() This includes concentrating, dreaming, meditation, memory retrieval, information processing and conscious perception - similar to those associated with memory flashbacks. The different types of oscillations, including gamma, are involved in high-cognitive functions, researchers said. ![]() Just before and after the heart stopped working, the team noticed changes in a specific band of brain waves - referred to as neural oscillations. "We measured 900 seconds of brain activity around the time of death and set a specific focus to investigate what happened in the 30 seconds before and after the heart stopped beating," said Zemmar, a neurosurgeon at the University of Louisville, who organized the study of the recording. But during these recordings, the patient had a heart attack and passed away, according to the statement.Īs a result, scientists recorded the activity of a dying human brain for the first time ever, the study authors said. The findings were somewhat accidental, in that an 87-year-old patient who developed epilepsy underwent electroencephalography (EEG) to detect the seizures.
