The compressed life review (CLR), also known as panoramic memories, total recall, replay of past experiences, or the life-review experience, is an intriguing mental phenomenon implying the extreme, yet instantaneous, manifestation of autobiographical memory (AM). ![]() The data suggest that CLR-like phenomenology may be successfully induced by triggering short-term access to the verbally cued SDMs and may be associated with specific patterns of visual activity that are not reportedly involved with deliberate autobiographical retrieval. In both conditions, stimuli caused relative visual immobilization, in contrast to listening to a single neutral phrase, and a choir of neutral phrases that led to active visual exploration. A significant similarity in eye movement patterns between a single SDM condition and a choir of SDM conditions in self-reported CLR experiencers was confirmed. The technique evoked a self-reported CLR-like experience in 10 out of 20 participants. It consists of listening to superimposed audio recordings of previously trained verbal cues to an individually composed set of self-defining memories (SDMs). A novel theoretically rooted laboratory-based experimental technique aimed to elicit the CLR-like experience with no risk to healthy participants was developed. To depart from this methodology, I considered the long-term working memory (WM), “concentric”, and “activation-based” models of memory. ![]() This research was guided by concerns over the retrospective methodology used in CLR studies. This is allowing scientists to objectively study the physiological and mental events that occur in relation to death.The compressed life review (CLR) is a mnemonic illusion of having “your entire life flashing before your eyes”. “What has enabled the scientific study of death is that brain cells do not become irreversibly damaged within minutes of oxygen deprivation when the heart stops,” explained Parnia. While that may sound pretty psychedelic, we also know that near-death experiences don’t have a lot in common with hallucinations, illusions, or psychedelic drug induced experiences – though they do often result in the same sort of positive long-term psychological transformation that recent studies have associated with the use of substances like psilocybin. Generally speaking, your average near-death experience involves first feeling separated from your body and having a heightened sense of consciousness and recognition of death next, a sense of travel to some destination followed by a meaningful and purposeful analysis of your actions, intentions and thoughts towards others throughout your life then, you’ll feel like you’re in a place that feels like “home”, before finally returning to the real world (and, probably, a lot of very relieved paramedics.) What is notable is that these experiences – of which there are hundreds of millions recorded from cultures around the world – consistently follow the same themes and narrative arcs. In fact, the researchers point out, evidence suggests that neither physiological nor cognitive processes end at the “point of death” – and while scientific studies have so far not been able to prove the reality of near-death experiences, neither can they disprove them. Today, drowning victims that suffer extreme hypothermia, lack of oxygen, and lack pulse and breathing for several hours can be revived (with luck and some heavy medical interventions).” ![]() “For a long time, a lack of breathing and pulse were regarded as hallmarks of death, until resuscitation methods improved. “eing ‘irreversibly dead’ is technology dependent,” wrote Anders Sandberg, a research fellow at the University of Oxford’s Future of Humanity Institute, back in 2016. The statement comes at a critical (no pun intended) time, as “death” in the 21st century isn’t the same as death even a hundred years ago. Published in the Annals of the New York Academy of Sciences, the paper is the first-ever peer-reviewed statement on the scientific study of death, and is designed to “provide insights into potential mechanisms, ethical implications, and methodologic considerations for systematic investigation” and “identify issues and controversies” in the research area. That’s why now, scientists from a wide range of disciplines have published a new consensus statement regarding the study of death. ![]()
