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.”

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.

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.
At least 51 people have died after heavy rain caused flash flooding, with water bursting from the banks of the Guadalupe River in Texas.
The overflowing water began sweeping into Kerr County and other areas around 4am local time on Friday, killing at least 43 people in the county.
This includes at least 15 children and 28 adults, with five children and 12 adults pending identification, Kerr County Sheriff Larry Leitha said at a news conference.
In nearby Kendall County, one person has died. At least four people were killed in Travis County, while at least two people died in Burnet County. Another person has died in the city of San Angelo in Tom Green County.

An unknown number of people remain missing, including 27 girls from Camp Mystic in Kerr County, a Christian summer camp along the Guadalupe River.
Rescuers have already saved hundreds of people and would work around the clock to find those still unaccounted for, Texas governor Greg Abbott said.
But as rescue teams are searching for the missing, Texas officials are facing scrutiny over their preparations and why residents and summer camps for children that are dotted along the river were not alerted sooner or told to evacuate.

AccuWeather said the private forecasting company and the National Weather Service (NWS) sent warnings about potential flash flooding hours before the devastation, urging people to move to higher ground and evacuate flood-prone areas.

The NWS later issued flash flood emergencies – a rare alert notifying of imminent danger.
“These warnings should have provided officials with ample time to evacuate camps such as Camp Mystic and get people to safety,” AccuWeather said in a statement that called Texas Hill County one of the most flash-flood-prone areas of the US because of its terrain and many water crossings.
But one NWS forecast earlier in the week had called for up to six inches of rain, said Nim Kidd, chief of the Texas Division of Emergency Management.”It did not predict the amount of rain that we saw,” he said.
Officials said they had not expected such an intense downpour of rain, equivalent to months’ worth in a few short hours, insisting that no one saw the flood potential coming.
One river near Camp Mystic rose 22ft in two hours, according to Bob Fogarty, meteorologist with the NWS’s Austin/San Antonio office. The gauge failed after recording a level of 29.5ft.

“People, businesses, and governments should take action based on Flash Flood Warnings that are issued, regardless of the rainfall amounts that have occurred or are forecast,” Jonathan Porter, chief meteorologist at AccuWeather, said in a statement.
“We know we get rain. We know the river rises,” said Kerr County Judge Rob Kelly, the county’s top elected official. “But nobody saw this coming.”
Judge Kelly said the county considered a flood warning system along the Guadalupe River that would have functioned like a tornado warning siren about six or seven years ago, before he was elected, but that the idea never got off the ground because “the public reeled at the cost”.

Homeland Security Secretary Kristi Noem was asked during a news conference on Saturday whether the flash flood warnings came through quickly enough: “We know that everyone wants more warning time, and that is why we are working to upgrade the technologies that have been neglected for far too long.”
Presidential cuts to climate and weather organisations have also been criticised in the wake of the floods after Donald Trump‘s administration ordered 800 job cuts at the science and climate organisation NOAA, the parent organisation of the NWS, which predicts and warns about extreme weather like the Texas floods.
A 30% cut to its budget is also in the pipeline, subject to approval by Congress.
Professor Costa Samaras, who worked on energy policy at the White House under President Joe Biden, said NOAA had been in the middle of developing new flood maps for neighbourhoods and that cuts to NOAA were “devastating”.
“Accurate weather forecasts matter. FEMA and NOAA matter. Because little girls’ lives matter,” said Frank Figliuzzi, a national security and intelligence analyst at Sky’s US partner organisation NBC News.
Radicalised nine-year-olds, teenagers mixing incel culture with extreme right ideologies and a Muslim who idolises Hitler – this is just some of the casework of those tasked with deradicalising young extremists in the UK.
Monday will mark 20 years since the 7/7 attacks on the London transport network when four suicide bombers killed 52 people and injured 770 others.
A year later the government set up its deradicalisation programme Prevent as part of its counter-terrorism strategy.
Sky News has spoken to two leading intervention providers (IPs) at Prevent who both say their work is getting ever more complex and the referrals younger.
The Metropolitan Police’s Prevent co-ordinator, Detective Superintendent Jane Corrigan, has also told Sky News it is “tragic” that when it comes to terrorism, “one in five of all our arrests is a child under 17”.
She believes parents should talk to their children about what they are reading and seeing online.
“Parents instinctively know when something doesn’t feel right when their child is becoming withdrawn or isolated – not wanting to engage,” she says.

‘A pic-n-mix of ideologies’
Home Office figures show 11-year-olds are the largest age group to get referred.
Concerning cases are passed on to IPs such as Nigel Bromage who told Sky News: “Often there will be a pic-n-mix of ideologies.
“From my own examples and experience, we are aware of people looking at the incel culture and mixing that with some far-right elements.”

Incels, meaning “involuntary celibates” are men who have been unable to have a relationship with women despite wanting one and become misogynistic and hateful as a result.
Like many IPs, Mr Bromage from Birmingham comes from an extremist background himself, having once been a regional organiser for the proscribed Neo-Nazi group Combat 18.
For him too, it began as a child.
“It all started with someone giving me a leaflet outside my school gates,” Mr Bromage says.
“It told me a horrific story about a mum getting killed by an IRA bomb explosion – and at the end of the leaflet there was a call to action which said: ‘If you think it’s wrong then do something about it’.”
He developed a hatred for Irish republican terrorism which morphed into general racism and national socialism.
“At the very end I thought I was going to go to prison, or I would end up being hurt or even killed because of my political beliefs,” he says.

Boy, 9, groomed by his brother
Mr Bromage reveals his youngest case was a nine-year-old who had been groomed by his brother.
“He was being shown pro-Nazi video games, and his older brother was saying ‘when I go to prison or I get in trouble – they you’re the next generation – you’re the one who needs to continue the fight’,” he says.
“Really, he had no interest in the racist games – he just wanted to impress his brother and be loved by his brother.”
Every year, nearly 300 children who are 10 or younger are referred to Prevent.
Home Office figures show that over the last six years 50% of referrals were children under the age of 18.
Eleven-year-olds alone make up a third of total referrals, averaging just over 2,000 a year, with the figure rising even higher in the most recent stats.
Another IP, Abdul Ahad, specialises in Islamic extremism.
He says the catalyst for radicalisation often comes from events aboard.
Ten years ago, it was Syria, more recently Gaza.
“It is often a misplaced desire to do something effective – to matter, to make a difference. It gives them purpose, camaraderie and belonging as well – you feel part of something bigger than you,” he says.

Clients want someone to ‘hear them’
Some of his clients “don’t fit into any particular box”.
“I’m working with a guy at the minute, he’s a young Muslim but he idolises Hitler and he’s written a manifesto,” he says.
“When you break it down, some people don’t know where they fit in, but they want to fit in somewhere.”
Mr Ahad says the young individual mostly admires Hitler’s “strength” rather than his ideologies and that he was drawn to darker characters in history.
Often his clients are very isolated and just want someone to “hear them”, he adds.
Image: Intervention provider Abdul Ahad specialises in Islamic extremism
Mr Ahad is also an imam who preaches at the Al-Azar Mosque in South Shields, a well-regarded centre for community cohesion and outreach.
He uses his understanding of the Islamic faith in his Prevent sessions to help guide his referrals away from extreme interpretations of the Koran by offering “understanding and context”.
He says: “We quote the correct religious texts – we explain their responsibility as a Muslim living in the UK and we re-direct their energies into something more constructive.”
Common theme of mental health issues
Mental health problems are a common theme among those referred to Prevent including depression and autism.
Her mother was critical of Prevent, as well as the police and MI5 after she had referred her daughter to the deradicalisation programme and Rhianan was subsequently charged with terrorism offences.
Last month a coroner found some failings in the processes around protecting Rhianan, but none of them attributable to Rhianan taking her own life.
Det Supt Corrigan says a referral doesn’t mean individuals end up being arrested or on an MI5 watchlist.
She says: “You’re not reporting a crime, but you are seeking support. I would say the earlier you can come in and talk to us about the concerns you have the better. Prevent is just that – it is a pre-criminal space.
“It’s tragic when you see the number of young people being arrested for very serious charges. Just look at terrorism – one in five of all our arrests is a child under the age of 17. We need to think about how we respond to that.”
Prevent has been criticised for failures such as when Southport killer Axel Rudakabana failed to be recognised as needing intervention despite three referrals, or when MP David Amiss’ killer Ali Harbi Ali went through the programme and killed anyway.

It’s harder to quantify its successes.
Mr Ahad says he understands why the failures hit the headlines, but he believes the programme is saving lives.
He says: “I think the vast majority of people get radicalised online because they are sitting in their room reading all this content without any context or scholarly input. They see one version of events and they get so far down the rabbit hole they can’t pull themselves out.
“I really wish Prevent was around when I was a young, lost 15-year-old because there was nothing around then. It’s about listening to people engaging with them and offering them a way of getting out of that extremism.”

‘Radicalisation can happen in days to weeks’
Det Supt Corrigan says: “I’ve sat with parents whose children have gone on to commit the most horrendous crimes and they all spotted something.
“Now, with hindsight, they wished they had done something or acted early. That’s why we created this programme, because radicalisation can happen in days to weeks.”
Twenty years on from 7/7 the shape of the terrorist threat has shifted, the thoughts behind it harder to categorise, but it is no less dangerous.

NEW YORK — A blunder that typifies the current state of the New York Yankees, who find themselves in the midst of their second six-game losing streak in three weeks, happened in front of 41,401 fans at Citi Field on Saturday, and almost nobody noticed.
The Yankees were jogging off the field after securing the third out of the fourth inning of their 12-6 loss to the Mets when shortstop Anthony Volpe, as is standard for teams across baseball at the end of innings, threw the ball to right fielder Aaron Judge as he crossed into the infield from right field.
Only Judge wasn’t looking, and the ball nailed him in the head, knocking his sunglasses off and leaving a small cut near his right eye. The wound required a bandage to stop the bleeding, but Judge stayed in the game.
“Confusion,” Yankees manager Aaron Boone said. “I didn’t know what happened initially. [It just] felt like something happened. Of course I was a little concerned.”
Avoiding an injury to the best player in baseball was on the Yankees’ very short list of positives in another sloppy, draining defeat to their crosstown rivals. With the loss, the Yankees, who held a three-game lead over the Toronto Blue Jays in the American League East standings entering June 30, find themselves tied with the Tampa Bay Rays for second place three games behind the Blue Jays heading into Sunday’s Subway Series finale.
The nosedive has been fueled by messy defense and a depleted pitching staff that has encountered a wall.
“It’s been a terrible week,” said Boone, who before the game announced starter Clarke Schmidt will likely undergo season-ending Tommy John surgery.
For the second straight day, the Mets capitalized on mistakes and cracked timely home runs. After slugging three homers in Friday’s series opener, the Mets hit three more Saturday — a grand slam in the first inning from Brandon Nimmo to take a 4-0 lead and two home runs from Pete Alonso to widen the gap.
Nimmo’s blast — his second grand slam in four days — came after Yankees left fielder Jasson Dominguez misplayed a ball hit by the Mets’ leadoff hitter in the first inning. On Friday, he misread Nimmo’s line drive and watched it sail over his head for a double. On Saturday, he was slow to react to Starling Marte’s flyball in the left-center field gap and braked without catching or stopping it, allowing Marte to advance to second for a double. Yankees starter Carlos Rodon then walked two batters to load the bases for Nimmo, who yanked a mistake, a 1-2 slider over the wall.
“That slider probably needs to be down,” said Rodon, who allowed seven runs (six earned) over five innings. “A lot of misses today and they punished them.”
Jazz Chisholm Jr.’s throwing woes at third base — a position the Yankees have asked him to play to accommodate DJ LeMahieu at second base — continued in the second inning when he fielded Tyrone Taylor’s groundball and sailed a toss over first baseman Cody Bellinger’s head. Taylor was given second base and scored moments later on Marte’s RBI single.
The Yankees were charged with their second error in the Mets’ four-run seventh inning when center fielder Trent Grisham charged Francisco Lindor’s single up the middle and had it bounce off the heel of his glove.
The mistake allowed a run to score from second base without a throw, extending the Mets lead back to three runs after the Yankees had chipped their deficit, and allowed a heads-up Lindor to advance to second base. Lindor later scored on Alonso’s second home run, a three-run blast off left-hander Jayvien Sandridge in the pitcher’s major league debut.
“Just got to play better,” Judge said. “That’s what it comes down to. It’s fundamentals. Making a routine play, routine. It’s just the little things. That’s what it kind of comes down to. But every good team goes through a couple bumps in the road.”
This six-game losing skid has looked very different from the Yankees’ first. That rough patch, consisting of losses to the Boston Red Sox and Los Angeles Angels, was propelled by offensive troubles. The Yankees scored six runs in the six games and gave up just 16. This time, run prevention is the issue; the Yankees have scored 34 runs and surrendered 54 in four games against the Blue Jays in Toronto and two in Queens.
“The offense is starting to swing the bat, put some runs on the board,” Boone said. “The pitching, which has kind of carried us a lot this season, has really, really struggled this week. We haven’t caught the ball as well as I think we should.
“So, look, when you live it and you’re going through it, it sucks, it hurts. But you got to be able to handle it. You got to be able to deal with it. You got to be able to weather it and come out of this and grow.”
