Chapter 24

Just a Dying Brain

“In his hand is the life of every living thing and the breath of all mankind.” — Job 12:10 (ESV)

A. The Strongest Case Against the Soul

A man’s heart stops on a hospital gurney in the Netherlands. Monitors flatline. The medical team begins CPR. A nurse removes his dentures and sets them in a sliding drawer in the crash cart. Over a week later, the man wakes from a coma. He spots that same nurse and says, “You know where my dentures are.” He describes the crash cart and the bottles on top of it. He names the drawer underneath where the dentures had been placed. He describes the room, the people in it, and the fact that the staff were “extremely negative” about his chances. All of it checks out.1

What do you do with a story like that? If you believe the brain is the whole person, if you believe that every thought and feeling is nothing more than neurons firing, then you need an explanation. How could a man whose heart had stopped and whose brain was shutting down describe what was happening in the room around him?

And plenty of smart, serious people have tried to give one. Over the past forty years, researchers have offered a long list of reasons why a near-death experience might be nothing more than a trick of the dying brain. They point to lack of oxygen. A flood of brain chemicals. Seizure activity in the temporal lobes. Dreams bleeding into waking thought. A last electrical surge before the lights go out. Each theory is worth hearing. Some of them do explain a piece of the puzzle.

But I want to show you, carefully and fairly, why none of them explains the whole picture. Not one of them can account for the man and his dentures. Not one can explain how a woman whose eyes were taped shut during brain surgery described the saw used to open her skull.2 Not one can explain how blind people report accurate visual details they had no natural way to know.3

In this chapter we give the skeptics their strongest arguments. We take each one seriously. And then we see where it breaks.

“I praise you, for I am fearfully and wonderfully made. Wonderful are your works; my soul knows it very well.” — Psalm 139:14 (ESV)

The psalmist was right. We are wonderfully made. And part of what makes us wonderful is that we are more than the body that holds us.

B. The Skeptic’s Case in Full

Before we answer the skeptics, we owe them a fair hearing. A good argument is answered at its strongest, not at its weakest. So here is the naturalistic case, stated plainly.

The human brain is the most complex organ we know of. It runs on oxygen and glucose delivered by the blood. When the heart stops or the blood supply drops, the brain begins to fail. And failing brains do strange things. They produce hallucinations, fragments of memory, and altered states of awareness. Maybe, the skeptic says, the near-death experience is one of those strange things.

Here are the main theories, each backed by real research from real scientists.

Plain Words

This chapter uses several medical terms. Here they are in plain English. Hypoxia means the brain is getting less oxygen than it needs. Anoxia means it is getting none. Hypercarbia means too much carbon dioxide has built up in the blood. Endorphins are natural painkillers the body makes under stress. DMT is a chemical found in tiny amounts in the brain that can cause hallucinations. Ketamine is a drug used for anesthesia that can also cause strange mental states. The temporal lobes are the parts of the brain near the ears that handle memory and emotion. REM stands for rapid eye movement, the sleep phase when most vivid dreams happen. Gamma waves are fast electrical signals in the brain linked with conscious thought. An EEG is a machine that measures the brain’s electrical activity. And veridical means confirmed to be true.

Oxygen Starvation

This is the oldest and most popular explanation. When the brain runs short of oxygen, a condition called hypoxia (or, in its severe form, anoxia), the person may have confusion, visual changes, and even tunnel-like vision. Test pilots who black out during high-G centrifuge training sometimes report fragments that sound a bit like NDEs. They describe tunnel vision, floating, pleasant feelings, and dreamlike images of friends or family.4 Psychologist Susan Blackmore offered one of the most developed versions of this theory. She argued that oxygen loss causes random firing in the visual cortex. Because the cortex has more cells in its center than at its edges, this firing creates the sense of a bright light at the center of a dark tunnel.5

Carbon Dioxide Buildup

When the body stops getting rid of carbon dioxide, the gas builds up in the blood. This condition is called hypercarbia. In the 1950s, psychiatrist L. J. Meduna treated patients by having them breathe a mix of oxygen and carbon dioxide. Some of them reported feelings of leaving the body, moving toward a light, and a deep sense of peace.6 A few researchers have pointed to these results as a possible cause of NDEs.

Brain Chemistry: Endorphins, Ketamine, and DMT

The body releases natural painkillers called endorphins under extreme stress. Perhaps these create the feeling of peace and bliss. Others have pointed to ketamine, an anesthetic drug. Ketamine can produce some NDE-like features: a sense of leaving the body, seeing a light, and feeling that the experience is deeply meaningful.7 Psychiatrist Karl Jansen proposed that the brain may release a ketamine-like substance when starved of oxygen. This chemical shield, he argued, protects neurons from damage but also produces an NDE-like experience as a side effect.8 Others suggest that DMT (dimethyltryptamine), a compound found in trace amounts in the brain, may surge during dying and trigger hallucinations.9

Temporal-Lobe Seizures and the “God Helmet”

The temporal lobes of the brain handle memory, emotion, and sensory processing. Seizures there can produce hallucinations, memory flashbacks, feelings of a strange presence, and déjà vu. Neuroscientist Michael Persinger claimed he could produce “all the major components of the NDE.” He did this by sending weak magnetic fields across the temporal lobes using a special helmet. The press called it the “God helmet.”10

REM Intrusion

Neurologist Kevin Nelson proposed that the brain’s dreaming machinery, the rapid eye movement (REM) system, can bleed into waking awareness during a medical crisis. In this view, NDEs are a kind of waking dream, produced by a brain that has lost its ability to keep sleep and waking cleanly separated.11

Expectation and Cultural Conditioning

Perhaps people see what they expect to see. Raised on stories of heaven, light, and angels, the dying brain simply pulls from its memory bank and builds a comforting scene.12

The Dying-Brain Electrical Surge

In recent years, researchers have found something surprising. The brains of dying animals and some dying humans produce brief, powerful surges of high-frequency electrical activity in the seconds after the heart stops. These are gamma waves, the kind associated with consciousness and higher mental function.13 Perhaps this surge is the reason NDEs feel so vivid and hyper-real.

That is the skeptic’s case. It is not foolish. Each piece points to something real about how the brain works. But the question is whether any of these theories, alone or together, can explain the full near-death experience. I do not believe they can. Here is why.

C. Why the Brain Theories Fall Short

1. Oxygen Starvation Predicts the Wrong Experience

The oxygen theory has a clean logic to it. The brain is dying, so it malfunctions, and the malfunction produces the NDE. But the trouble is that we know exactly what oxygen loss does to the brain. It has been studied in thousands of experiments on thousands of people. And what it produces is the opposite of what NDErs report.

When oxygen drops, thinking becomes slow and confused. Mountain climbers at extreme altitude report mental laziness, irritability, and difficulty concentrating. Medical students in controlled hypoxia experiments became progressively more disoriented until they passed out.14 In thousands of such experiments, not a single person reported an NDE.

NDEs, by contrast, involve heightened clarity. People describe their thinking as sharper than normal, more vivid, more ordered. They recall the experience years later with perfect detail. A brain that is shutting down does not do this. A failing brain, as neuropsychiatrist Peter Fenwick has pointed out, produces experiences that are “limited, confused, and disorganized. The very opposite is true of the NDE.”15

The Severity Correlation

In my doctoral research, I found a positive correlation between the severity of the medical crisis and the quality of confirmed perception during the NDE. The sicker the brain was, the clearer and more accurate the experience became. Among the scholarly cases, patients in cardiac arrest with EEG monitoring scored an average veridical quality of 46.6. Those in cardiac arrest without monitoring scored 32.1. Those in other life-threatening events scored 26.4. EEG-documented cases across the full database averaged 38.7. This is exactly the opposite of what the oxygen theory predicts. If NDEs were caused by a failing brain, the worst medical crises should produce the most confused experiences. Instead, they produce the most vivid and most verifiable ones.16

And there is one more problem. Many NDEs occur when oxygen levels are normal. In the prospective Dutch study by cardiologist Pim van Lommel and his colleagues, blood gas levels were monitored during cardiac arrest and resuscitation. Patients who reported NDEs had oxygen levels the same as, or actually higher than, patients who did not report NDEs.17 The same pattern appeared in a British study published in the journal Resuscitation.18 If low oxygen caused NDEs, the patients with the least oxygen should have been the ones with the most vivid experiences. They were not.

Beyond this, the experiences of test pilots in centrifuge training differ from NDEs in almost every important way. Pilots report tunnel vision, which is the absence of peripheral sight caused by low blood pressure in the eyeballs. NDErs report passing through a tunnel, which is a full, three-dimensional sense of movement through space. These are very different things. Pilots have brief, random dreamlets about living friends in ordinary settings. NDErs meet deceased relatives and a being of light. Pilots do not have life reviews. Pilots do not make a decision to return. And pilots do not report the lasting changes in values and behavior that are so common after an NDE.19

What about carbon dioxide? The hypercarbia theory faces similar trouble. In a cardiac arrest, carbon dioxide does build up. But the buildup is always joined by a drop in oxygen, which brings its own confusion and disorientation. Peter Fenwick noted that no good ICU would tolerate a dangerous carbon dioxide level without intervening. And where carbon dioxide levels have been measured during NDEs, they have come back normal or below normal.54 The Meduna experiments did produce some experiences with NDE-like elements. But they also produced things never found in NDEs: brightly colored geometric patterns, objects seen in double or triple, and violent convulsive movements. The overlap is real but thin.

2. Brain Chemistry Cannot Cross the Perception Gap

The chemical theories are clever. I find the ketamine model, in particular, worth taking seriously. Karl Jansen proposed that the brain may flood its own receptors with a ketamine-like substance to protect neurons from damage when oxygen runs low. The side effect of this chemical shield, he argued, would be an NDE-like experience.20

And the model rests on two assumptions that have never been confirmed. First, no such naturally occurring ketamine-like substance has been found in the human brain.21 Second, ketamine experiences do not reliably resemble NDEs. Ketamine trips vary widely depending on the dose, the setting, and the user’s mental state. NDEs, by contrast, follow a remarkably consistent pattern regardless of the person’s expectations.22 Peter and Elizabeth Fenwick made a telling observation. Someone who attempts suicide might be in emotional turmoil beforehand. But if they have an NDE, the turmoil vanishes. It is replaced by peace and beauty. The NDE does not seem to care what emotional state came before it.23

The endorphin theory faces its own trouble. Endorphins might explain a feeling of calm under extreme stress. That is what they do. A woman attacked at an ATM reported that after the initial terror, an overwhelming calm took over and her body went limp. That was almost certainly endorphins at work.53 But endorphins do not explain structured visions of another world. They do not explain encounters with deceased relatives or the kind of panoramic life review that NDErs describe. The same goes for DMT. No study has shown that DMT levels surge during dying. And even if they did, drug-induced hallucinations differ from NDEs in one way that matters most.

Here is the gap that no chemical theory can cross: drug states do not produce confirmed, accurate perception of real events happening at a distance from the body. A person on ketamine may feel that they have left their body. But they cannot describe the shoes on the ledge outside the hospital window.24 They cannot identify the serial number on a piece of medical equipment they have never seen. They cannot report, with verifiable accuracy, what the surgical team said while the patient’s eyes were taped shut and brain was monitored flat. NDErs can and do. In my doctoral research, 105 cases involved patients whose eyes were taped shut during surgery. Those cases averaged a veridical quality score of 36.1, far above the overall average. Even if a person were to take the most potent hallucinogenic drug in the world, it would not allow them to know what was happening in a different room. That is what separates the near-death experience from every known drug state.55

Carter on the Chemical Theories

“At this point, all theories involving neurotransmitters are little more than pure speculation, as they are all difficult to test directly. We cannot stick probes into numerous brain areas to take tissue samples from dying patients or of patients undergoing resuscitation.” — Chris Carter, Science and the Near-Death Experience25

3. The Temporal Lobe and the “God Helmet”

The idea that temporal-lobe seizures might explain NDEs has been around for decades. It draws on the pioneering work of neurosurgeon Wilder Penfield, who electrically stimulated the temporal lobes of patients during brain surgery. Some researchers claimed that Penfield produced out-of-body experiences, visions of dead relatives, and panoramic life reviews through his electrical probes.26

But when you actually read Penfield’s own reports, the picture looks very different. Out of 1,132 patients he stimulated, only two reported anything even vaguely like leaving the body. One man said, “Oh God! I am leaving my body,” and looked terrified. A woman said she felt “as though I were half and half here.” Neither described seeing themselves from above. Neither had a life review, a being of light, or an encounter with the dead.27 What Penfield actually found was more ordinary. Electrical stimulation of the temporal lobe produced random, mundane memories. Patients heard hallucinated sounds like a song from the radio. Some felt déjà vu.28

Ernst Rodin, medical director of the Epilepsy Center of Michigan, put it bluntly after three decades of work with temporal-lobe seizure patients. He had never once seen the core features of an NDE during a seizure. The hallmarks of an NDE are peace, a sense of having died, and freedom from the body. Seizures, by contrast, bring fear, loneliness, and sadness.29

There is a deeper problem, too. Seizures and cardiac arrest produce opposite brain states. A seizure means the brain is in overdrive, with chaotic, high-amplitude electrical spiking on the EEG. Cardiac arrest means the opposite: the EEG goes flat within seconds. These two conditions cannot exist at the same time. And the most evidentially powerful NDEs happen during cardiac arrest, when seizure activity can be ruled out entirely. In my doctoral research, 1,680 cases occurred during cardiac arrest with monitoring. Sixty-six of those had documented EEG readings, and those EEG-documented cases produced the highest veridical scores of any category. A theory built on seizures cannot explain experiences that happen when the brain shows no electrical activity at all.57

As for Persinger and the “God helmet,” the claims turned out to be inflated. When you look at his published data, the most common experiences his subjects reported were dizziness and tingling, which are not features of NDEs. The experiences were fragmentary and variable, not ordered and consistent. And when a Swedish team tried to replicate his results using his own equipment, they failed. They concluded that the likeliest explanation for Persinger’s results was simple suggestibility: people sitting in the dark, wearing a strange helmet, expecting something unusual to happen.30

What Stimulation Produces vs. What NDEs Produce

Electrical stimulation of the brain produces random memory fragments, feelings of strangeness, and simple sensory distortions. NDEs produce ordered, structured experiences of leaving the body, entering another world, meeting deceased loved ones, and encountering a being of light. The two look nothing alike in their overall pattern. As Bruce Greyson has noted, patients whose brains are being stimulated describe the sensations as unrealistic and dreamlike. NDErs describe their experience as undeniably real, often “more real than real.”31

4. REM Intrusion and Expectation

Kevin Nelson proposed that NDEs happen when the brain’s REM dreaming system invades waking awareness. He reported that NDErs showed a higher rate of REM intrusion symptoms than non-NDErs. But Greyson and Jeffrey Long pointed out a basic problem. The rate Nelson found in his NDEr group was no higher than the rate of the same symptoms in the general population. The difference came from his control group, which underreported symptoms that are actually quite common.32

There are deeper problems as well. Many NDEs happen under general anesthesia, which suppresses REM activity. If REM intrusion caused NDEs, patients under anesthesia should not have them. But they do. And when researchers measured REM-related brain activity in NDErs, they found something surprising. It was actually lower than in people who had never had an NDE.33

The sleep-paralysis experience common in REM intrusion involves fear and a sense of threat, sometimes a dark figure pressing on the chest. The NDE, in most cases, is the opposite: peace, light, and love. As neurosurgeon Eben Alexander put it from his own experience, equating NDEs with dreams is like comparing the experience of watching a war movie with the experience of actually fighting in a battle.34

The expectation theory fares no better. If NDEs were built from cultural expectations, then people should see what their culture teaches them to see. Christians should see pearly gates. Hindus should see the Yamuna River. Atheists should see nothing. But NDEs regularly defy expectations. People report experiences that conflict with what they believed about death.35 Reports from before 1975, when Raymond Moody’s book first made NDEs widely known, are not meaningfully different from reports gathered after it. Young children, who carry the least cultural baggage about death, report the same core features as adults (see Chapter 11). And in my doctoral research, the core features of NDEs remained remarkably consistent across seven decades of data. In the 985 cases before 1975 and the 4,289 after it, the average veridical score was identical: 22.0 in both groups. Out-of-body experiences appeared in 89 percent of early cases and 84 percent of later ones. Life reviews held steady at about 23 percent in both eras. Even the percentage of NDEs mentioning Jesus barely changed, from 12.5 percent before 1975 to 12.4 percent after. If culture were writing the script, the script should have changed as the culture changed. It did not.36

5. The Dying-Brain Electrical Surge

This is the newest entry on the skeptic’s list, and it deserves careful attention. In 2009, intensive-care physician Lakhmir Chawla at George Washington University noticed something strange. After his patients died, their brain-wave monitors showed a brief, unexpected spike of high-frequency electrical activity.37 He initially dismissed it. The brain cannot be active after death. But the signal was gamma waves, the kind of brain activity associated with consciousness, learning, and memory. Other researchers found the same thing. In 2013, Jimo Borjigin and colleagues showed that dying rats produced a surge of high-frequency brain oscillations after their hearts stopped.38 In 2022, a neurosurgeon at the University of Louisville found bursts of gamma waves in the brain of an eighty-seven-year-old man in the seconds surrounding his death.39

These findings are real and fascinating. I want to be clear about that. The brain does not simply go dark the moment the heart stops. Something happens. And the researchers who study it deserve credit for opening a new window on what happens in the last moments of life. But the surge does not explain NDEs, for three reasons.

First, the surges are brief. They last seconds, sometimes less. They appear to be a final flicker of electrical activity as the brain shuts down, not a sustained state of consciousness. And they have not been shown to produce any particular experience. We know the surge happens. We do not know that it produces anything the dying person is aware of. As Sam Parnia has observed, finding brain activity during death is one thing. Showing that it is the cause of a complex, ordered, hyper-real experience is another thing entirely.40

Second, many NDEs involve experiences that unfold over what feels like minutes or longer. The life review alone can cover an entire lifetime of events. A gamma-wave burst lasting a few seconds is not a plausible container for that kind of rich, detailed, structured experience.

Third, and most importantly, a burst of brain activity is not the same as accurate perception of the room. Even if the surge does produce some kind of internal experience, it cannot explain how a patient describes what the nurse did with his dentures during CPR. It cannot explain how someone reports a verified conversation from a hallway two floors away. The surge might explain a flash of vivid inner experience. It cannot explain the perception of external events that are later confirmed by witnesses. That is the gap no brain theory can close.

6. The One Thing No Brain Theory Explains

We have walked through six categories of naturalistic explanation. Each one has something to offer. Oxygen loss can produce visual disturbances. Chemicals can produce feelings of calm. Temporal-lobe activity can produce fragments of memory. And yes, the dying brain may have one last surge of electrical activity.

But there is one fact that none of these theories can touch.

People who are clinically dead report accurate, detailed, verified perceptions of events around them. Their hearts have stopped. Their brains show no measurable electrical activity. And sometimes the events they describe happened far away from them. (For the full evidence, see Chapter 9.)

After the onset of cardiac arrest, blood flow to the brain ceases. Consciousness is lost within seconds. The EEG goes flat within ten to twenty seconds. There is no electrical activity in the cortex. Animal studies have confirmed that deep brain structures also go quiet shortly after. No neuroscientific model has ever proposed that complex, lucid thought can occur in this state.41

And yet some patients report exactly that. They describe structured, coherent, vivid experiences during the time when their brains were flatlined. And the details they report check out.

The Data Behind the Claim

In my doctoral research, I analyzed 5,278 near-death experiences. Of those, 30.7 percent (1,618 cases) met the criteria for “Exceptional” or “Strong” evidence that consciousness was operating apart from the brain. Over 1,100 cases involved accurate observation of things at a distance from the body. Thirty-three cases involved blind people reporting verified sight. The scholarly, qualitatively documented cases scored far higher on evidence quality than the self-reported online accounts, with average scores of 31.2 versus 20.7. Among cases with EEG monitoring during cardiac arrest, sixty-three involved veridical observations made while the brain showed no organized electrical activity. In 105 cases, the patient’s eyes were taped shut. In every category, the more severe the physical crisis, the higher the quality of the confirmed perception. That pattern runs in exactly the wrong direction for any brain-based explanation.42

Cardiologist Pim van Lommel has framed the problem clearly. The question is not whether there might be some trace of unmeasurable brain activity somewhere deep in the cortex. The question is whether there is brain activity of the specific kind that modern neuroscience says is necessary for conscious experience. And there is no sign of it during cardiac arrest.43

This is the rock that every naturalistic explanation breaks on. You can explain the feeling of peace with endorphins. You can explain a sensation of floating with temporal-lobe activity. You can explain a flash of light with a dying-brain surge. But you cannot explain how a patient with a flat EEG accurately describes the instruments on the surgical tray, the words the doctor whispered, or the shoes on the ledge outside a third-floor window. A hallucination does not get the details right. A dream does not match the medical record. The confirmed, accurate, veridical cases are the evidence that the brain theories cannot reach. And they are the evidence that points most strongly to a soul that can see, hear, and know when the body has stopped working.

D. What the Researchers Say

Chris Carter, whose book Science and the Near-Death Experience remains the most thorough survey of the naturalistic explanations, concludes that every proposed brain-based theory either rests on unverified speculation or fails to account for the most important features of NDEs, especially veridical perception during documented brain shutdown.44

Sam Parnia, the physician who led the landmark AWARE studies of cardiac-arrest patients, has pointed out that the occurrence of lucid, well-structured thought during cardiac arrest raises profound questions. These experiences happen at a time when cerebral function can be described, at best, as severely impaired and, at worst, as absent. Any reduction in cerebral blood flow leads to impaired attention and higher brain function. NDEs during cardiac arrest are clearly not confused. They indicate heightened awareness and attention at a time when neither would be expected.45

Bruce Greyson, who has studied NDEs for over forty years and developed the standard scale used to measure them, has examined each category of naturalistic explanation and found them wanting. On REM intrusion, he showed that the data did not support Nelson’s claims. On temporal-lobe theories, he found that seizures produce fragmentary, fear-laden episodes that bear little resemblance to the ordered, peaceful NDE. On the surge theory, he has noted that bursts of brain activity after death have not been shown to produce any particular experience, much less one with verified external content.46

John Hagan, editor of a peer-reviewed volume on NDE science for the Missouri State Medical Association, summarized the state of the research. NDEs may occur without oxygen loss or abnormal carbon dioxide levels. NDEs happen under general anesthesia, which suppresses REM activity. No single physiological or chemical mechanism has been shown to produce the rich, complex, consistent pattern of the NDE. And confirmed perception from a viewpoint outside the body, later verified as correct, cannot be explained by any known brain process.47

J. Steve Miller, whose work surveys the naturalistic explanations and asks which hypothesis best fits the facts, reached a similar conclusion. After examining each proposed brain-based theory, Miller found that competent NDE researchers had tested these explanations again and again and ruled them out. He framed the question the way a careful scientist would. Set up two hypotheses: the naturalistic “dying brain hypothesis” and the “afterlife hypothesis.” Then ask which one best explains the data. Miller concluded that the dying brain hypothesis fails on the evidence that matters most. Hundreds of highly documented cases show patients with alert consciousness and accurate observations even when both heart and brain activity had ceased.56

To be fair, the skeptics have done valuable work too. Susan Blackmore’s Dying to Live was a serious and respectful attempt to build a complete brain-based model. Kevin Nelson’s REM research raised real questions. G. M. Woerlee has pressed hard on anesthesia cases, asking whether patients might retain more awareness than we think. These are not foolish people, and their challenges have made the NDE research stronger.48 But even Blackmore acknowledged that her model rested largely on speculation about what might happen in the dying brain, not on proven facts about what does.49

E. Answering the Pushback

Even after walking through the evidence, honest people raise further objections. Here are the four strongest, stated at their best.

“You’re Committing a God-of-the-Gaps Fallacy”

This is the most common pushback, and it deserves a careful answer. A god-of-the-gaps argument says, “I cannot explain it, therefore God did it.” That would be a weak argument. But that is not what we are doing here. We are not pointing to a gap in knowledge and filling it with the supernatural. We are pointing to positive evidence: hundreds of cases where patients accurately perceived things they could not have known by any natural means, often during documented brain shutdown. The argument is not “we don’t know how the brain does this, so it must be a soul.” The argument is that we have strong positive evidence. Conscious perception occurred when the brain was not working. The best explanation for that evidence is that consciousness can work apart from the brain.50

“The absence of a mechanism is not proof of a soul.”

This is true. We are not claiming that our inability to find a brain-based explanation proves that the soul exists. What we are saying is that every proposed brain-based explanation has been tested against the data and found wanting. That does not end the conversation, but it does shift the burden. If there were no cases of verified perception during brain shutdown, the brain theories would be enough. There are such cases, and they are well documented (see Chapter 9). The question is not whether we have a complete mechanism. The question is which explanation best fits the evidence we have.

“Future neuroscience will explain it.”

Maybe. Science advances. No honest person should claim that a naturalistic explanation is impossible in principle. But we should notice something: this objection is not an argument. It is a promissory note. We are being asked to believe that someday, somehow, a scientist will figure out how a brain with no electrical activity can perceive events in another room. That is not a theory. It is a hope dressed up as patience. And it cuts both ways. You could use the same move to dismiss any evidence for anything: “We cannot explain it now, but someday we will.” At some point, the evidence in hand deserves a response.51

“The veridical cases are weaker than claimed.”

Some skeptics argue that the confirmed perception cases rely on anecdotes, fuzzy memories, and retrospective reporting. This is a fair concern, and it is one of the reasons why prospective hospital studies matter so much (see Chapter 12). But the concern does not erase the data. Michael Sabom matched patient reports against surgical records and found them accurate. Ring and Cooper documented blind people reporting visual details they could not have known. Van Lommel’s and Parnia’s prospective studies interviewed patients shortly after cardiac arrest and recorded their accounts alongside medical records. In my own research, fifteen cases were documented before anyone else could have told the patient what had happened. Another 1,250 were documented within twenty-four hours of the event, while the memories were fresh. The scholarly cases scored far higher on evidence quality than the self-reported ones, and the best-documented cases are the hardest to explain away.52 No single case proves everything. But the pattern across hundreds of cases, gathered by independent researchers in different countries over several decades, is not easily dismissed.

F. More Than a Brain

We have given the skeptics a fair hearing. Oxygen loss, brain chemicals, temporal-lobe activity, REM intrusion, expectation, and the dying-brain surge each explain a small piece of the NDE puzzle. But not one of them, and not all of them together, can explain how a man with no heartbeat knew where the nurse put his dentures. Not one can explain how a woman whose brain was being monitored flat during surgery later described the instruments on the tray. Not one can explain how blind people see.

The simplest explanation, and the one that fits the evidence best, is that these people were seeing because something in them was still awake, still aware, still able to perceive, even after the body had stopped. That something is what the Bible calls the soul.

I want to be honest about what this chapter does and does not prove. It does not prove the soul exists with the certainty of a lab experiment. What it does is show that every purely physical explanation has been tested and found to fall short of the evidence. The data point, with real force, beyond the brain.

And the alternatives are not equal. On one side, we have a list of theories, each of which can explain a fragment but none of which can explain the whole. On the other side, we have one simple claim: something in these people was still awake when the body had stopped. That claim fits all of the data. It fits the vivid clarity when the brain was failing. It fits the accurate perception when the eyes were closed or the cortex was flatlined. It fits the consistency across cultures, across decades, and across age groups. It fits what the dying have been telling us for centuries.

If you are a person of faith, that should strengthen your confidence. The Bible has always told us that we are more than our bodies. God formed us from dust and breathed life into us (Genesis 2:7). He made us body and soul. And when the body stops, the soul does not stop with it. The dying do not slip into nothing. The evidence says what Scripture has always said: there is a person inside the body, and that person lives on.

I do not think the skeptics are foolish. I think they are doing their job. Good science tests every natural explanation before looking beyond nature. That is exactly what has happened with NDEs. Researcher after researcher has proposed a brain-based theory. Researcher after researcher has tested it against the data. And after four decades of testing, the natural explanations still cannot account for the strongest cases.

“In his hand is the life of every living thing and the breath of all mankind.” — Job 12:10 (ESV)

And if you are a skeptic who has read this far with an open mind, I want to thank you. I know that what I am claiming sounds extraordinary. It is. But the evidence is extraordinary too. I am not asking you to set aside your reason. I am asking you to follow it where the data lead.

A Sound Reply Is Not a Blank Check

Showing that the brain theories fall short does not mean that every NDE is from God, or that every detail of every experience should be trusted. The fact that NDEs are genuine does not automatically make their content reliable. A person may truly leave their body and still misinterpret what they encounter on the other side. Satan can counterfeit a genuine experience (2 Corinthians 11:14). Answering the skeptic is only half the job. The other half is testing the experience against Scripture. For that, see Chapter 23 and Appendix C.

We are not just a dying brain. We are fearfully and wonderfully made, body and soul, by a God who holds the life of every living thing in His hand.

Notes

1. The “dentures case” was reported in a prospective Dutch study of cardiac-arrest survivors. See Pim van Lommel, Ruud van Wees, Vincent Meyers, and Ingrid Elfferich, “Near-Death Experience in Survivors of Cardiac Arrest: A Prospective Study in the Netherlands,” The Lancet 358 (2001): 2039–2045. The case is discussed at length in Chris Carter, Science and the Near-Death Experience: How Consciousness Survives Death (Rochester, VT: Inner Traditions, 2010), chap. 13.

2. The Pam Reynolds case. See Michael Sabom, Light and Death: One Doctor’s Fascinating Account of Near-Death Experiences (Grand Rapids: Zondervan, 1998), 37–52. For the full treatment of veridical cases, see Chapter 9.

5. Susan Blackmore and T. S. Troscianko argued that random neural firing in the oxygen-deprived visual cortex, which has more cells devoted to the center than the periphery, could produce the impression of a bright light at the center of darkness. See Susan Blackmore, Dying to Live: Near-Death Experiences (Buffalo, NY: Prometheus Books, 1993), chap. 5. Carter critiques this model in Science and the Near-Death Experience, chap. 11.

6. L. J. Meduna’s carbon-dioxide treatment experiments are discussed in Carter, Science and the Near-Death Experience, chap. 11. See also P. M. H. Atwater, The Big Book of Near-Death Experiences (Charlottesville, VA: Hampton Roads, 2007), chap. 13.

7. For an overview of the ketamine comparison, see Carter, Science and the Near-Death Experience, chap. 12. See also Karl Jansen, “Near-Death Experience and the NMDA Receptor,” British Medical Journal 298 (1989): 1708.

8. Jansen argued that a ketamine-like substance might be released to block NMDA receptors and protect neurons from glutamate-mediated excitotoxicity. The resulting side effect, in his view, would mimic the NDE. See Jansen, “Near-Death Experience and the NMDA Receptor.” Carter evaluates the model in Science and the Near-Death Experience, chap. 12.

9. Rick Strassman, DMT: The Spirit Molecule (Rochester, VT: Park Street Press, 2001). The suggestion remains speculative; no study has demonstrated that DMT levels surge during the dying process. See Bruce Greyson, After: A Doctor Explores What Near-Death Experiences Reveal about Life and Beyond (New York: St. Martin’s, 2021), chap. 6.

10. Michael A. Persinger, “Modern Neuroscience and Near-Death Experiences: Expectancies and Implications,” Journal of Near-Death Studies 7, no. 4 (Summer 1989): 233–239. Persinger claimed to have replicated “all the major components of the NDE.” Carter examines his published data in Science and the Near-Death Experience, chap. 11.

15. Peter Fenwick, quoted in Carter, Science and the Near-Death Experience, chap. 11. Fenwick is a neuropsychiatrist who studied over three hundred NDE cases.

16. The author’s Th.D. dissertation (Trinity Theological Seminary) analyzed 5,278 near-death experiences and found a positive correlation between the severity of the medical crisis and the evidence-quality score of the reported experience. Among the scholarly cases, cardiac arrest with monitoring averaged a veridical quality score of 46.6; coma cases averaged 33.8; cardiac arrest without monitoring averaged 32.1; and other life-threatening events averaged 26.4. EEG-documented cases across the full database averaged 38.7, the highest of any monitoring category.

Yeates, and Peter Fenwick, “A Qualitative and Quantitative Study of the Incidence, Features and Aetiology of Near-Death Experiences in Cardiac Arrest Survivors,” Resuscitation 48 (2001): 149–156. Patients who had NDEs had oxygen levels as high as or higher than those who did not.

19. Carter catalogues these differences in Science and the Near-Death Experience, chap. 11: no panoramic life review, no deceased relatives, no being of light, no decision to return, no lasting personality transformation. See also Whinnery, “Psychophysiologic Correlates,” 231–258.

20. Jansen, “Near-Death Experience and the NMDA Receptor.” Carter calls Jansen’s model “the most sophisticated attempt so far to provide an explanation for the NDE in terms of brain chemistry.” See Carter, Science and the Near-Death Experience, chap. 12.

21. Strassman noted that a naturally occurring ketamine-like substance “has not been identified in humans.” Carter, Science and the Near-Death Experience, chap. 12.

22. Carter, Science and the Near-Death Experience, chap. 12. The effects of ketamine depend greatly on set and setting, but NDEs are surprisingly similar regardless of cause or circumstance.

24. The “Maria’s shoe” case, reported by social worker Kimberly Clark Sharp, involves a patient who described a dark-blue tennis shoe with a worn little toe and a lace tucked under the heel on a third-floor window ledge. For discussion and the fuller treatment, see Chapter 9.

26. Melvin Morse, David Venecia, and Jerrold Milstein, “Near-Death Experiences: A Neurophysiologic Explanatory Model,” Journal of Near-Death Studies 8 (1989): 45–53. Morse and co-author Paul Perry described finding, in what they called “a forty-year old textbook,” evidence that Penfield had produced NDE-like experiences. Carter shows that the actual Penfield data do not support this claim. See Carter, Science and the Near-Death Experience, chap. 11.

27. Greyson, After, chap. 6. Greyson notes that out of Penfield’s 1,132 patients, only two reported anything even vaguely resembling an OBE, and neither involved the classic NDE features of seeing oneself from above, meeting deceased loved ones, or encountering a being of light.

They compared Nelson’s figures against published rates of REM intrusion symptoms in the general population (e.g., Maurice M. Ohayon et al., “Prevalence of Narcolepsy Symptomatology and Diagnosis in the European General Population,” Neurology 58, no. 12 [2002]: 1826–1833).

33. Greyson, After, chap. 6. General anesthesia suppresses REM brain activity, yet NDEs occur under anesthesia. See Arthur J. Cronin et al., “Postoperative Sleep Disturbance: Influences of Opioids and Pain in Humans,” Sleep 24, no. 1 (2001): 39–44.

34. Greyson, After, chap. 6. The comparison of NDEs to watching a war movie versus actually fighting in a battle illustrates the qualitative difference between laboratory-induced sensations and the NDE.

35. Greyson, in Hagan, The Science of Near-Death Experiences, chap. 2. Individuals often report experiences that conflict with their personal and religious expectations. People with no prior knowledge of NDEs describe the same core features as those familiar with them.

36. The author’s Th.D. dissertation (Trinity Theological Seminary). In the 985 pre-1975 cases and 4,289 post-1975 cases, the average veridical score was 22.0 in both groups; OBE rates were 89.2% and 83.9%; life-review rates were 23.4% and 23.6%; encounters with beings were 66.7% and 69.5%; and mentions of Jesus were 12.5% and 12.4%. This consistency indicates that NDE content is an inherent feature of the experience rather than a cultural contamination from popular NDE accounts after Moody.

40. Parnia, Lucid Dying, chap. 4. Parnia’s AWARE-II study measured electrical signs of lucid brain activity during cardiac arrest, but distinguishes between the detection of brain waves and their causal role in the reported experience.

41. Carter, Science and the Near-Death Experience, chap. 13. EEG flat-lines within ten to twenty seconds of cardiac arrest. Animal studies with deep-brain electrodes confirm that deeper brain structures also lose activity shortly after cortical activity ceases. See also van Lommel, “Setting the Record Straight,” 107–119.

42. The author’s Th.D. dissertation (Trinity Theological Seminary). Among the 5,278 cases analyzed, 1,618 (30.7%) met the criteria for “Exceptional” or “Strong” evidence; 1,114 involved accurate distant observation; 33 involved verified sight in blind NDErs; scholarly cases averaged an evidence-quality score of 31.2 versus 20.7 for self-reported online cases. Sixty-three cases involved veridical observations during documented flatline EEG; 105 involved patients whose eyes were taped shut (average veridical score 36.1). Fifteen cases were documented before the patient could have received outside information, and 1,250 more within twenty-four hours of the event.

49. Blackmore acknowledged, “What happens to the brain when a person approaches death? A first approximation to an answer is simply to say that we do not know.” See Blackmore, Dying to Live.

50. The god-of-the-gaps objection is addressed at length in Carter, Science and the Near-Death Experience, introduction and conclusion. The argument from veridical perception is a positive evidential argument, not an argument from ignorance.

51. This objection is addressed in Carter, Science and the Near-Death Experience, conclusion. A promissory-note defense can be applied to any evidence for any conclusion and is therefore not a real argument against the current data.

52. The author’s Th.D. dissertation (Trinity Theological Seminary). Scholarly cases scored 31.2 versus 20.7 for self-reported cases, a large and statistically significant gap. Fifteen cases were documented before any outside information could have reached the patient; an additional 1,250 were documented within twenty-four hours of the NDE. See also Sabom, Light and Death, and Ring and Cooper, Mindsight, for detailed matching of patient reports against medical records.

53. This case, used to illustrate endorphin action under extreme stress, is described in Sabom, Light and Death, chap. 10. The woman’s sudden calm during a life-threatening attack almost certainly resulted from the release of endorphins, not from a near-death experience.

54. Peter Fenwick, quoted in Carter, Science and the Near-Death Experience, chap. 11. Several studies have reported carbon dioxide levels to be normal or below normal during NDEs. See also Greyson, in Hagan, The Science of Near-Death Experiences, chap. 2; Parnia et al., “A Qualitative and Quantitative Study,” 149–156.

55. The author’s Th.D. dissertation (Trinity Theological Seminary). Of the 105 cases in the database where the patient’s eyes were taped shut during surgery, the average veridical quality score was 36.1, with 71.4 percent meeting the threshold for high veridical evidence. If sensory perception requires functioning sense organs, these cases should not exist.

56. J. Steve Miller, Near-Death Experiences as Evidence for the Existence of God and Heaven (Acworth, GA: Wisdom Creek Press, 2012), chaps. 4–6. Miller follows Susan Blackmore’s own framework of testing two hypotheses — the “dying brain hypothesis” and the “afterlife hypothesis” — against the available data, then asks which hypothesis has the most explanatory power. See also Miller, Is Christianity Compatible with Deathbed and Near-Death Experiences? (Wisdom Creek Press, 2023), chap. 1.

57. The author’s Th.D. dissertation (Trinity Theological Seminary). Among the 1,680 NDE cases occurring during cardiac arrest with monitoring, 66 had documented EEG readings. Those EEG-documented cases averaged a veridical quality score of 38.7, the highest of any medical category. The brain cannot exhibit seizure activity and electrocerebral silence at the same time; the most evidentially powerful NDEs occur precisely when seizure activity can be ruled out.
