“…Parnia et al reports in two prospective multicentre studies that cardiac arrest survivors may have intense memories from the resuscitation. 6 , 12 The authors argue that such experiences may promote emotional damage such as cognitive deficits or post-traumatic stress disorder both for the patients and the rescuers. 6 In a letter to the editor of Resuscitation, Rice et al argues that ‘ A patient making purposeful movements, even being awake and alert while in cardiac arrest, can have profound emotional and psychological implications on the patient as well as the paramedic providers caring for them’ .…”

“… 2 However, most are case reports, a few prospective studies on patients, 5 , 6 , 7 , 8 reports on the rescuers’ experience 4 , 9 , 10 and a scoping review, 11 in addition to a prospective study of in-hospital CPRIC. 12 This increase in publications may be due to increased prevalence, increased focus on the condition, or both. The reported prevalence of CPRIC was 0.23–0.9%, 11 but the design of the studies greatly influences the validity of the data.…”

“…Again, there was no obvious difference in the pharmacology of resuscitation efforts. More recently, Parnia et al 28 , 29 conducted the AWAreness during REsuscitation (AWARE) studies (AWARE I in 2014 and AWARE II in 2023). AWARE I was a prospective, multicenter observational investigation of cardiac arrest survivors, with 140 patients studied for a stage 1 interview and 101 of those patients who completed stage 2 interviews.…”

“…AWARE II was a 25-site prospective study that included more objective measures such as audiovisual testing using a computer and headphones, continuous electroencephalography, and cerebral oximetry. 29 There were 567 in-hospital cardiac arrests, of which 53 survived, of which 28 were available for interviews. Of those available for interviews, 21.4% had what was categorized as a transcendent recalled experience of death (a term proposed to replace near-death experience).…”

The near-death experience has been reported since antiquity and is often characterized by the perception of light, interactions with other entities, and life recall. Near-death experiences can occur in a variety of situations, but they have been studied systematically after in-hospital cardiac arrest, with an incidence of 10 to 20%. Long attributed to metaphysical or supernatural causes, there have been recent advances in understanding the neurophysiologic basis of this unique category of conscious experience. This article reviews the epidemiology and neurobiology of near-death experiences, with a focus on clinical and laboratory evidence for a surge of neurophysiologic gamma oscillations and cortical connectivity after cardiac and respiratory arrest.

“…Consciousness is generally understood as distinct, personal experiences of changing perceptual, mental, emotional and bodily states. We are considered "conscious" when we can report what we are experiencing (Parnia et al, 2023). When we cannot report our experience, we are considered unconscious, such as during sleep.…”

Researchers are exploring consciousness as a field permeating the world around us, rather than just a feature of human experience. If consciousness is a field, then one should be able to affect others by acting from the field of consciousness. This study used a random-assignment, double-blind design to probe effects of nine students practicing the Transcendental Meditation technique on the subjective experiences and physiological patterns of another student also practicing Transcendental Meditation. For 12 recording sessions, the group (sender) either practiced the Transcendental Meditation technique or read a textbook. When the group was meditating, the individual (receiver) reported more settled meditation experiences, and they exhibited higher alpha EEG power, a correlate of deep meditation experiences. Effect sizes for all measures were large. This was a pilot study to identify markers of field effects of consciousness. Future research could replicate these findings with a larger sample size, modify the distance between the sender and receiver, explore EEG synchrony between the senders and the receiver, called hyperscanning or collective neuroscience, and explore differential effects between friends, family, and strangers to test social influences. This design could meaningful probe the nature of consciousness.
