A Twilight Between Life and Death

The Story That Should Not Have Happened

On October 26, 2021, at Baptist Health Richmond in Kentucky, something unfolded that still feels difficult to categorize. Anthony TJ Hoover II, 36 years old, had overdosed. Doctors examined him carefully. No reflexes. No detectable brain activity. He was declared brain dead. His family, processing shock in that flat, stunned way grief often arrives, agreed to organ donation because that is what he had wanted.

About an hour into the surgical preparation, everything changed.

According to a later whistleblower account sent to Congress, Hoover began thrashing on the operating table. Not a twitch. Not a reflexive jerk. Movement. Intentional enough that surgeons stopped immediately. Somehow, against medical expectation, he had regained consciousness.

He survived. Not unscathed. The overdose left lasting impairments in speech, memory, and mobility. But he survived. Eventually, he was discharged into the care of his sister.

Cases like his unsettle something deep in us. We rely on medicine to define boundaries. Alive. Dead. Irreversible. Final. Clean lines make difficult decisions bearable. But Hoover’s case, along with scattered reports from places as far apart as Kenya, Poland, Ecuador, and China, forces an uncomfortable question into the room.

What if death is not a single, catastrophic switch flipped all at once?

What if it is, instead, a process with blurred edges?

The Clean Model We Prefer

The traditional biological model is straightforward. When oxygen stops reaching the brain and electrical activity ceases, consciousness ends. Lights out. System failure. No residual awareness. No hidden flicker.

It is a tidy model. It is emotionally survivable.

However, recent research has complicated that narrative. Not in a dramatic, cinematic way. No bright halos or mystical proclamations. Just data. Electrical traces. Subtle surges.

Researchers have detected bursts of gamma brainwaves, high frequency electrical activity in the 30 to 100 hertz range, even after the heart begins to fail.

Gamma waves are not random noise. They are associated with memory integration, conscious awareness, attention. The kind of neural coordination you see when someone is actively perceiving the world, dreaming vividly, or experiencing psychedelic states.

So why would a brain, deprived of oxygen and approaching shutdown, produce activity typically linked to awareness?

That is the part that does not sit easily.

The Michigan Findings

In 2023, researchers at the University of Michigan analyzed EEG and ECG recordings from four comatose patients whose ventilators were withdrawn. EEG tracks electrical activity in the brain. ECG monitors the heart’s electrical rhythm. These patients were unresponsive. Their prognosis had been deemed hopeless.

In two of the four cases, something remarkable happened as cardiac function declined. There was a sudden surge of gamma activity. Not chaotic noise. Not scattered firing.

Organized. Synchronized with slower brain rhythms. Highly coordinated across regions.

The surge was particularly strong in what neuroscientists call the posterior hot zone, an area involved in vision, bodily awareness, and sensory processing. Connectivity even extended toward frontal regions, creating patterns that resemble those observed in dreaming and conscious perception.

For a brief moment, it was as if the brain lit up from within.

Jimo Borjigin, a neuroscientist involved in the study, described the activity as highly organized. Motion areas activated. Speech regions showed engagement. Even the temporal parietal junction, a region associated with integrating sensory input and sometimes linked to out of body experiences, showed involvement.

That pattern matters. It suggests coordination. And coordination implies purpose, or at least structured function.

Yet these patients were not recovering. They did not return to life. The activity occurred at the threshold of physiological collapse.

So what was the brain doing?

A Last Attempt to Stay

One hypothesis Borjigin has proposed is both biological and strangely human. The brain might be launching a final internal search for survival.

Think about it. The brain consumes roughly 20 percent of the body’s energy under normal circumstances. In a state of oxygen deprivation, energy is scarce. Why spend it generating complex activity?

It feels inefficient. Almost desperate.

Some people who report near death experiences describe reliving intense emotional memories. Seeing deceased relatives. Hearing phrases like it is not your time. Moving through tunnels of light. These narratives are surprisingly consistent across cultures.

Could those experiences correlate with organized gamma surges in regions responsible for memory and sensory reconstruction?

Possibly.

When oxygen drops, neurons become unstable. Networks can enter hyperexcitable states. It is conceivable that the brain, sensing catastrophic failure, activates deeply embedded circuits tied to survival, attachment, meaning.

Or perhaps it is simpler. Maybe the disinhibition caused by metabolic collapse triggers synchronized firing that mimics conscious states without actually generating awareness.

The honest answer is we do not know.

And that uncertainty matters.

Twilight Consciousness

Borjigin has used the phrase twilight consciousness. It is an evocative term. Not fully awake. Not fully gone. A liminal state.

We tend to imagine coma as absence. Blankness. But neuroimaging studies over the past decade have repeatedly shown that some comatose patients exhibit covert awareness. In rare cases, patients who appear entirely unresponsive can modulate brain activity when instructed to imagine specific tasks.

From the outside, nothing. Internally, something.

That should make us pause.

If organized gamma activity can occur in patients deemed beyond recovery, then the dying process may involve phases of internal experience invisible to observers.

That does not mean people are fully conscious after death. It does mean the boundary is not as clean as textbooks once implied.

And maybe it never was.

The Organ Donation Question

This is where the conversation becomes delicate.

Organ donation saves countless lives. That is not in dispute. Protocols are rigorous. Determination of death criteria exist precisely to prevent premature retrieval.

However, if covert signs of brain activity are missed, especially with surface level EEG monitoring or in settings without advanced neuroimaging, the timing of death declaration deserves scrutiny.

Caroline Watt, emeritus professor at the University of Edinburgh, has pointed out that cardiac arrest does not automatically equal brain death. Brain activity can persist briefly after the heart stops. And in many deaths outside hospitals, no brain monitoring occurs at all.

Does this mean widespread misclassification? No. Cases like Hoover’s are extremely rare. But rarity does not equal impossibility.

Medicine has evolved precisely because it confronts edge cases.

The Skeptical View

Not everyone finds the gamma surge data persuasive.

Bruce Greyson, psychiatrist and longtime researcher of near death experiences at the University of Virginia, urges caution. He notes that in the Michigan cases, the heart was still beating when the gamma bursts occurred. Oxygen, even if reduced, was still circulating. Therefore, he argues, the data do not represent true post death activity.

Moreover, none of the patients survived. There is no way to correlate the electrical patterns with reported subjective experiences.

He also raises an important methodological concern. Gamma signals can be contaminated by muscle artifacts. Subtle electrical noise may masquerade as neural synchronization.

In other words, the data are intriguing. They are not definitive.

Greyson himself has spent decades studying near death experiences. In his book After: A Doctor Explores What Near-Death Experiences Reveal About Life and Beyond, he argues that such experiences challenge strictly materialist models of consciousness. Yet he stops short of claiming proof that awareness survives death.

That restraint is worth noting.

Speculation is easy. Evidence is harder.

Stories That Refuse to Fade

Then there are the anecdotes. And anecdotes are dangerous territory in science. They stir emotion. They are hard to verify. They resist clean categorization.

In 2012, a 95 year old woman named Li Xiufeng in Guangxi province, China, was reportedly declared dead after a fall. Her body lay in an open casket for several days before she climbed out and cooked porridge. She later said she had slept a long time and woke up hungry.

It sounds absurd. It sounds folkloric.

Yet documented cases of premature death declaration have occurred historically, especially before modern monitoring techniques. There are archived reports of individuals awakening in morgues or during funeral preparations.

Most such stories likely involve misdiagnosis. Hypothermia. Drug intoxication. Cataleptic states. Severe metabolic suppression.

Still, the fact that misclassification can occur at all reinforces a simple truth.

Biology is messy.

The Hard Question

What actually happens when we die?

Not philosophically. Not spiritually. Biologically.

Cells do not all die at once. Neurons depolarize. Ion gradients collapse. Some tissues remain viable longer than others. Molecular cascades unfold over minutes and hours.

Even at the cellular level, death is not instantaneous. It is a process.

The larger question is whether subjective experience could persist briefly during that cascade. A few seconds. Perhaps longer under certain conditions.

If gamma surges reflect structured neural firing, they might represent a final integrative event. A last burst of coordinated activity as networks destabilize.

Or they might be nothing more than the electrical equivalent of a flickering bulb before darkness.

We need better data. Larger sample sizes. High resolution intracranial monitoring. Cross validation across institutions. Transparent methodology.

Instead, what we currently have are four patients and a handful of signals.

It is not nothing. But it is not enough.

Consciousness Itself Is Still a Mystery

Part of the difficulty is that consciousness remains poorly understood even in living, healthy individuals.

We can correlate neural patterns with subjective reports. We can observe synchronized gamma activity during perception. We can disrupt awareness with anesthesia. But we cannot yet explain how electrical activity becomes experience.

That explanatory gap complicates interpretation.

If we do not fully understand how consciousness arises in ordinary states, how can we confidently declare what happens at its boundary?

Greyson has quoted researchers like Sam Parnia in noting that the relationship between brain and consciousness remains one of science’s biggest mysteries. That statement is not mystical. It is empirical humility.

The brain is a physical organ. But subjective awareness, the feeling of being someone, remains resistant to reduction.

Between Fear and Curiosity

There is also a psychological dimension here.

Humans fear premature burial. The idea of being conscious yet unable to communicate has haunted literature for centuries. Even today, that archetypal anxiety lingers.

Borjigin has half jokingly suggested placing cameras inside coffins. The comment is provocative, perhaps intentionally so. But behind it lies a serious proposal. A global reassessment of how we define and detect death.

Death is universal. It is the one condition every organism will eventually meet. Yet, comparatively speaking, it has not been studied with the same intensity as cancer, cardiovascular disease, or neurodegeneration.

Part of that may be cultural discomfort. Part may be practical limitation. You cannot ethically experiment freely at the threshold of death.

Still, improved monitoring technologies could yield insights without compromising dignity or ethics.

What We Can Say, Carefully

So where does this leave us?

First, death is a process, not a moment. That is biologically accurate.

Second, transient organized brain activity can occur near the end of life, at least in some cases.

Third, whether that activity corresponds to subjective experience remains unproven.

Fourth, current medical protocols are built on the best available evidence and are continually refined. Rare anomalies do not invalidate the system, but they do justify ongoing scrutiny.

Finally, we should resist both extremes. It is premature to declare that consciousness survives death. It is equally premature to insist that the brain becomes instantly inert at cardiac arrest.

Reality is probably more complex than either narrative.

A Flicker, Not a Revelation

When people imagine revelations at death, they often picture clarity. A tunnel. A voice. A reunion.

What the data show, at least so far, is less poetic. Brief surges of electrical coherence. A brain attempting, perhaps reflexively, to integrate failing systems.

There is something almost tragic about that. The brain, an organ evolved for survival, might execute one final coordinated effort even as resources vanish.

Or perhaps that is projection. Perhaps we are anthropomorphizing ionic flux.

The disciplined position is this: we do not yet know.

And maybe that uncertainty is not a weakness. It is an invitation.

An invitation to study more rigorously. To measure more precisely. To refine our definitions.

Death may not be the instantaneous blackout we once imagined. But neither is there compelling evidence that it is a doorway.

For now, it appears to be a narrowing corridor. Activity dimming. Systems collapsing in sequence. Occasionally, a flicker of light before the dark.

Whether that flicker carries experience, memory, or meaning remains one of the most profound unanswered questions in neuroscience.

And perhaps that is fitting.

Because if there is one frontier humanity has never fully mapped, it is the border between being and not being.

We are only just beginning to look closely.
