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.

Israeli military announces 'tactical pause' in fighting in parts of Gaza amid hunger crisis

Israel has begun a pause in fighting in three areas of Gaza to address the worsening humanitarian situation.

The IDF said it would halt fighting in three areas, Muwasi, Deir al-Balah and Gaza City, from 10am to 8pm local time until further notice, beginning today.

In a statement, the IDF said it would also establish secure routes to help the UN and aid agencies deliver food and other supplies.

Israel’s announcement of what it calls a “tactical pause” in fighting comes after it resumed airdrops of aid into Gaza.

While the IDF reiterated claims there is “no starvation” in Gaza, it said the airdrops would include “seven pallets of aid containing flour, sugar and canned food to be provided by international organisations”.

Reports suggest aid has already been dropped into Gaza, with some injured after fighting broke out.

In other developments, Bob Geldof has accused Israeli authorities of “lying” about starvation in the territory – telling Sunday Morning With Trevor Phillips the IDF is “dangling food in front of starving, panicked, exhausted mothers”.

He told Sky News: “This month, up to now, 1,000 children or 1,000 people have died of starvation. I’m really not interested in what either of these sides are saying.”

Bob Geldof: ‘Israeli authorities are lying’

Israel cut off all supplies to Gaza from the start of March. It then reopened aid centres with new restrictions in May, but said the supply had to be controlled to prevent it from being stolen by Hamas militants.

On Saturday, reports referencing US government data said there was no evidence Hamas had stolen aid from UN agencies.

The IDF’s international spokesperson, Lieutenant Colonel Nadav Shoshani, described such reports as “fake news” and said Hamas thefts have been “well documented”.

Malnourished girl: ‘The war changed me’

Airdrops ‘expensive and inefficient’

It comes as the Hamas-run health ministry in Gaza said as of Saturday, 127 people have died from malnutrition-related causes, including 85 children.

They include a five-month-old girl who weighed less than when she was born, with a doctor at Nasser Hospital describing it as a case of “severe, severe starvation”.

Health workers have also been weakened by hunger, with some putting themselves on IV drips so they can keep treating badly malnourished patients.

Aid waiting to be distributed in Gaza

On Friday, Israel said it would allow foreign countries to airdrop aid into Gaza – but the UN Relief and Works Agency (UNRWA) has warned this will not reverse “deepening starvation”.

UNRWA head Philippe Lazzarini described the method as “expensive” and “inefficient”, adding: “It is a distraction and screensmoke. A manmade hunger can only be addressed by political will.

“Lift the siege, open the gates and guarantee safe movements and dignified access to people in need.”

UNRWA has the equivalent of 6,000 trucks in Jordan and Egypt waiting for permission to enter Gaza, he added.

PM says UK will help drop aid to Gaza

MSF, also known as Doctors Without Borders, warned on Friday that 25% of young children and pregnant women in Gaza are now malnourished, and said the lack of food and water on the ground was “unconscionable”.

The UN also estimates Israeli forces have killed more than 1,000 people seeking food, the majority near the militarised distribution sites of the US-backed aid distribution scheme run by the Gaza Humanitarian Foundation.

In a statement on Friday, the IDF had said it “categorically rejects the claims of intentional harm to civilians”, and reports of incidents at aid distribution sites were “under examination”.

The Gaza Humanitarian Foundation (GHF) has also previously disputed these deaths were connected with its organisation’s operations, with director Johnnie Moore telling Sky News: “We just want to feed Gazans. That’s the only thing that we want to do.”

‘I still have hope’: Parents of IDF soldier taken hostage by Hamas fear he’ll be one of last freed

'I still have hope': Parents of IDF soldier taken hostage by Hamas fear he'll be one of last freed

Yehuda searches through a downstairs room looking for a plastic bag containing the most precious of objects.

It’s a small, blackened Rubik’s Cube that belongs to Yehuda’s son Nimrod – one of 20 living Israeli hostages still being held by the terrorist group Hamas in Gaza.

It was found in Nimrod’s burnt-out tank after the October 7th attacks.

“He likes PlayStation and Rubik’s Cube,” says Nimrod’s mother, Vicky.

“They found the Rubik’s Cube in the tank. It was complete but a little bit dark and they brought it back to us.”

We spoke to Nimrod’s parents Yehuda and Vicky about the emotional rollercoaster hostage families in Israel are going through – as hope rises and fades of a ceasefire agreement with Hamas.

“I still have hope that maybe I will see Nimrod again,” says Vicky.

“It almost breaks my heart because I still had expectation,” she says – in spite of the latest failure to find resolution in talks between Israel and Hamas in Doha.

“But I still have hope that maybe something good will happen,” she says.

Vicky says: “We heard [during] the last weeks, President Trump saying we will hear about a ceasefire soon – next week – in a few days.

“We heard our prime minister [Benjamin Netanyahu] say visiting Washington and meeting Trump was very successful – and heard members of the coalition talking about our prime minister eventually understanding he needs to end the war. But until now nothing.”

The delegation coming back to Israel doesn’t mean a total collapse of ceasefire talks, but US envoy Steve Witkoff said the response to the latest ceasefire proposals by Hamas showed “a lack of desire”.

And so the rollercoaster of emotion for the hostage families continues.

Nimrod’s father Yehuda Cohen said: “Of course it’s a disappointment but it’s not the first one. A long time ago I learned not to get my expectations up so the disappointment won’t be too deep.

“The solution is very simple – I’ve got it on my shirt – ceasefire and hostage deal. Meaning the only way to get all the hostages is ending the war.”

Yehuda shows us Nimrod’s bedroom at the family home. It’s exactly as it was when Nimrod left to return to his army duties a few days before the October 7 attacks.

Except in a corner, there’s a box of uniforms and personal possessions, including a wallet which Nimrod had left at his army outpost – all returned to the family by the IDF.

It’s just like the bedroom of any other teenager – Nimrod was 19 when he was kidnapped. But two birthdays have passed since then. Nimrod is 21 now – a milestone spent in captivity a few weeks ago.

It’s believed there are 20 living Israeli hostages in Gaza – all male – and that Hamas is holding the bodies of 27 more hostages who have been killed.

Starvation in Gaza continues

But even if a deal is agreed, the first phase is expected to secure the release of only half of the living hostages – and Nimrod’s parents say their son, as a soldier, is not likely to be one of the 10.

Yehuda says: “A partial deal means that the probability my son will be on that list is close to zero. So he’s going to be one of the last ones to be released, and that’s why we have to fight.”

Bob Geldof accuses Israeli authorities of 'lying' about starvation in Gaza

Bob Geldof has accused the Israeli authorities of “lying” about starvation in Gaza – after Israel’s government spokesperson claimed there was “no famine caused by Israel”.

Earlier this week, David Mencer claimed that Hamas “starves its own people” while on The News Hour with Mark Austin, denying that Israel was responsible for mass hunger in Gaza.

Appearing on Sunday Morning with Trevor Phillips, Geldof said the claims are false.

Israel challenged on starvation in Gaza

Sir Trevor asked the Live Aid organiser: “The Israeli view is that there is no famine caused by Israel, there’s a manmade shortage, but it’s been engineered by Hamas.

“I guess the Israelis would say we don’t see much criticism from your side of Hamas.”

In response, Geldof said “that’s a false equivalence” and “the Israeli authorities are lying”.

The singer then added: “They’re lying. [Benjamin] Netanyahu lies, is a liar. The IDF are lying. They’re dangling food in front of starving, panicked, exhausted mothers.

“And while they arrive to accept the tiny amount of food that this sort of set up pantomime outfit, the Gaza Humanitarian Front, I would call it, as they dangle it, then they’re shot wantonly.

“This month, up to now, 1,000 children or 1,000 people have died of starvation. I’m really not interested in what either of these sides are saying.”

He added: “If the newsfeeds and social feeds weren’t so censored in Israel, I imagine that the Israeli people would not permit what has been done in their name.”

Asked about the UK government’s reaction, Geldof said it was “not enough”.

“This is a distraction thing about ‘let’s recognise the state ‘ – absolutely, it should have been done ages ago, but it’s not going to make any material difference,” he said, referring to calls for Sir Keir Starmer to recognise Palestine as a state.

Gaza: ‘This is man-made starvation’

In the Sky News interview earlier this week, Mr Mencer added: “This suffering exists because Hamas made it so. Here are the facts. Aid is flowing, through the Gaza Humanitarian Foundation. Millions of meals are being delivered directly to civilians.”

He also claimed that, since May, more than 4,400 aid trucks had entered Gaza carrying supplies.

It comes after MSF, also known as Doctors Without Borders, warned 25% of young children and pregnant women in Gaza are now malnourished.

The charity said Israel’s “deliberate use of starvation as a weapon” has reached unprecedented levels, and said that at one of its clinics in Gaza City, rates of severe malnutrition in children under five have trebled over the past two weeks.

MSF then described the lack of food and water on the ground “unconscionable”.

Aid waiting to be distributed in Gaza

In a statement to Sky News, an Israeli security official said that “despite the false claims that are being spread, the State of Israel does not limit the number of humanitarian aid trucks entering the Gaza Strip”.

It then blamed other groups for issues delivering aid. They said: “Over the past month, we have witnessed a significant decline in the collection of aid from the crossings into the Gaza Strip by international aid organisations.

“The delays in collection by the UN and international organisations harm the situation and the food security of Gaza’s residents.”

The IDF also told Sky News: “The IDF allows the American civilian organisation (GHF) to distribute aid to Gaza residents independently, and operates in proximity to the new distribution zones to enable the distribution alongside the continuation of IDF operational activities in the Gaza Strip.

“Following incidents in which harm to civilians who arrived at distribution facilities was reported, thorough examinations were conducted in the Southern Command and instructions were issued to forces in the field following lessons learned.

“The aforementioned incidents are under review by the competent authorities in the IDF.”
