In their last minutes of life, some people’s brains generate a surge of surprisingly organized-looking electrical activity that may reflect consciousness — although scientists aren’t entirely sure. 

According to new research, published Monday (May 1) in the journal PNAS (opens in new tab) , this surge can sometimes occur after a person’s breathing stops but before the brain stops functioning. The activity pattern is somewhat similar to what is seen when people are awake or in dreamlike states, leading to speculation that perhaps these electrical surges reflect the otherworldly experiences reported by people who’ve had close brushes with death: A sense of looking at the body from the outside; a tunnel and white light; or a sense of reliving important memories. 

However, since all the patients in the new study ultimately died, it’s impossible to know if they had such experiences. 

“If you talk about the dying process, there is very little we know,” said Jimo Borjigin (opens in new tab) , a neuroscientist at the University of Michigan Medical School who led the study. It’s rare for patients to have their brains continuously monitored as they die, Borjigin told Live Science. “This is maybe the first study to really show second-by-second how the brain dies.” 

Related: Is brain death reversible? Near-death experiences 

Some people who are brought back from the brink of death report seeing or hearing unexplained things during resuscitation or when they seem to be unconscious. The reason for these near-death experiences is unknown, and it’s not clear if they’re even specific to death. 

International surveys suggest that only about half of what people call “near-death experiences” actually occur in life-threatening situations, said Daniel Kondziella (opens in new tab) , a neurologist at the University of Copenhagen who was not involved in the new research. The other half occur during meditation or in scary situations that don’t endanger one’s health or impact the brain’s metabolism, Kondiziella told Live Science. 

“The thing is, from the experience itself you cannot say if someone has had a cardiac arrest or syncope [a brief loss of consciousness] or near-miss traffic accident,” Kondiziella said. 

Because the people who survive to report a near-death experience are inherently different from the people who die — their brains don’t permanently lose function, for one thing — it’s hard to determine whether those who actually die also have these subjective experiences. 

In 2013, Borjigin and her colleagues measured electrical activity in the brains of rats (opens in new tab) that they euthanized via cardiac arrest. They found that for about 30 seconds after the heart stopped, the brain showed a surge in what are called gamma waves, which are the highest-frequency electrical oscillations in the brain. Gamma waves are correlated with conscious experience, but don’t necessarily prove that someone is conscious; they’re just one of many indicators that someone might be aware and alert. 

In 2022, a separate group of doctors happened to be monitoring the brain of an 87-year-old man with an electroencephalogram (EEG), which detects electrical activity on the surface of the brain, when the man unexpectedly died. Similar to Borjigin’s rats, the man’s brain showed a surge in gamma activity in the 30 seconds before and after his heart stopped.  ‘Reading’ the dying brain 

In their new paper, Borjigin and her team made a deliberate effort to use EEG to capture what the brain looks like during death. 

The researchers got permission to monitor dying patients in intensive care whose breathing support had been removed after treatment proved futile. The study included four patients total, all of whom were comatose after cardiac arrest. 

In the 30 seconds to two minutes after their ventilators were removed, two of the four patients’ brains showed surges in gamma waves. Interestingly, this gamma activity seemed organized, in that the gamma waves in one portion of the brain were associated with predictable activity patterns in other regions. 

The temporoparietal junction, a brain region where the temporal and parietal lobes meet, toward the back of the brain behind the ear, was particularly active with gamma waves. This region is known to be activated when people have out-of-body experiences or dreams, Borjigin said. 

The new findings echo what was seen in the 87-year-old patient who unexpectedly died, said Raul Vicente (opens in new tab) , a neuroscientist and data scientist at the University of Tartu who co-authored the 2022 study but was not involved in Borjigin’s work. “It’s very nice to see a confirmation,” he told Live Science. 

“The more consistent findings we have, the more evidence it is that this likely is a mechanism happening at the time of death and if we can pinpoint this down to one location, even better,” said Ajmal Zemmar (opens in new tab) , a neurosurgeon at the University of Louisville Health who also co-authored the 2022 study. RELATED STORIES—Dying brains silence themselves in a dark wave of ‘spreading depression’

—Can minds persist when they are cut off from the world?

Zemmar and Vicente are optimistic that these signals could be signs of conscious experience at the moment of death. But reflecting the debate in the field, Kondziella is more skeptical. 

“We know when you die a cardiac death as opposed to a brain death, that takes time,” he said. Minutes pass between the heart stopping and brain cells dying, he said. “It shouldn’t be a big surprise during those minutes, you will see aberrant electrophysiological activity in the brain.” 

Some people may experience something like near-death experiences in these moments, Kondziella said, but we may never know for sure. And again, these experiences may not be unique to death — a more likely explanation for near-death experiences that encompasses both life-threatening experiences and non-life-threatening experiences, he said, may be “REM sleep intrusion into wakefulness,” a situation in which the brain blends waking and dreaming states. (REM sleep is marked by dreaming and brain activity patterns that are very similar to waking, including gamma waves and other, lower-frequency waves.) 

Borjigin’s team is still collecting end-of-life data, hoping to add to the evidence that the dying brain may generate predictable gamma-wave patterns. Already, other research groups have attempted to use artificial intelligence to identify objects that people saw in their dreams (opens in new tab) based on their brain activity — similar mind-reading may be possible with unconscious and dying patients, Vicente said. 

“This opens an opportunity at some point, if we gather enough data, to be able to decode what people in different coma states are thinking,” Vicente said.

European leaders to meet in Ukraine for 'coalition of the willing' talks - and issue call to Russia

Sir Keir Starmer will join other European leaders in Kyiv on Saturday for talks on the “coalition of the willing”.

The prime minister is attending the event alongside French President Emmanuel Macron, recently-elected German Chancellor Friedrich Merz and Polish Prime Minister Donald Tusk.

It will be the first time the leaders of the four countries will travel to Ukraine at the same time – on board a train to Kyiv – with their meeting hosted by President Volodymyr Zelenskyy.

Military officers from around 30 countries have been involved in drawing up plans for the coalition, which would provide a peacekeeping force in the event of a ceasefire being agreed between Russia and Ukraine.

Ahead of the meeting on Saturday, Sir Keir, Mr Macron, Mr Tusk and Mr Merz released a joint statement voicing support for Ukraine and calling on Russia to agree to a 30-day ceasefire.

“We reiterate our backing for President Trump’s calls for a peace deal and call on Russia to stop obstructing efforts to secure an enduring peace,” they said.

“Alongside the US, we call on Russia to agree a full and unconditional 30-day ceasefire to create the space for talks on a just and lasting peace.”

The leaders said they were “ready to support peace talks as soon as possible”.

But they warned that they would continue to “ratchet up pressure on Russia’s war machine” until Moscow agrees to a lasting ceasefire.

“We are clear the bloodshed must end, Russia must stop its illegal invasion, and Ukraine must be able to prosper as a safe, secure and sovereign nation within its internationally recognised borders for generations to come,” their statement added.

“We will continue to increase our support for Ukraine.”

The European leaders are set to visit the Maidan, a central square in Ukraine’s capital where flags represent those who died in the war.

They are also expected to host a virtual meeting for other leaders in the “coalition of the willing” to update them on progress towards a peacekeeping force.

This force “would help regenerate Ukraine’s armed forces after any peace deal and strengthen confidence in any future peace”, according to Number 10.

The ‘tricky balancing act’ facing Starmer over US trade deal – and the real challenge to come

The 'tricky balancing act' facing Starmer over US trade deal - and the real challenge to come

If you want a very visual representation of the challenges of transatlantic diplomacy in 2025, look no further than Oslo City Hall.

Its marbled mural-clad walls played home to a European military summit on Friday.

In December – as it does every year – it will host the Nobel Peace Prize ceremony. It’s an award Donald Trump has said he deserves to win.

But while the leaders gathering in the Norwegian capital may not say it publicly, they all have a very different perspective to the US president on how to win the peace – particularly when it comes to Ukraine.

So far, Sir Keir Starmer has managed to paper over these foreign policy gaps between the US and Europe with warm words and niceties.

But squaring the two sides off on trade may be more difficult.

The US-UK deal announced on Thursday contained no obvious red flags that could scupper deeper trade links with the EU.

PM defends UK-US trade deal

However, that’s in part because it was more a reaction and remedy to Mr Trump’s tariff regime than a proactive attempt to meld the two countries together.

Laced with party-political venom, yes, but the Tory leader Kemi Badenoch is getting at something when she says this agreement is “not even a trade deal, it’s a tariff deal and we are in a worse position now than we were six weeks ago”.

There may be more to come though.

How good is the UK-US deal?

The government will talk up the possible benefits, but there are risks too.

Take the Digital Services Tax – much hated by the Trump White House as an unfair levy on US tech firms.

Despite the apparent pitch-rolling from the government, that was left untouched this week.

But asked to rule out changes in the future, the prime minister was non-committal, simply saying the current deal “doesn’t cover that”.

For trade expert David Henig, the potential flashpoints in the transatlantic Venn diagram Downing Street is trying to draw around food standards, digital regulation and services.

“It is a tricky balancing act, at this stage it looks like the UK will go more with the EU on goods regulations, but perhaps a little bit more with the US on services regulations,” he said.

For veterans of the post-2016 Brexit battles, this may all sound like Labour embracing the Boris Johnson-era mantra of “cakeism” – or trying to have it both ways.

It’s ironic indeed, given Sir Keir is a politician who supported the Remain campaign and then called for a second referendum.

But what matters now is what works – not for Downing Street but for the swathes of voters who have abandoned Labour since they took office.

That’s why the prime minister was once again trying to humanise this week’s trade deals.

These are agreements, he said, that would be measured in the “many thousands of jobs” they would safeguard across the country.

That’s the real challenge now, taking the work done in the marbled halls of the world’s capitals and convincing people at home why it matters to them.
