A medical company set up by Elon Musk is under investigation for potential welfare violations – with a total of 1,500 animals dying in four years, according to a report.
Staff at Neuralink have made internal complaints that animal testing is being rushed – causing needless suffering and deaths, Reuters says.
Records seen by the news agency allege that 280 sheep, pigs and monkeys have died following experiments since 2018.
Neuralink is developing a brain implant that it hopes will help paralysed people walk again – and cure other neurological issues.
The complaints made by staff allege that Musk has increased pressure to accelerate development, leading to botched experiments that need to be repeated.
In one case, 25 pigs were reportedly implanted with devices that were the wrong size – with a source telling Reuters this was an error that could have been avoided with more preparation.

Earlier this year, a Neuralink executive reportedly sent staff a news article about Swiss researchers who developed an electrical implant that helped a man to walk again.
He wrote: “In general, we are simply not moving fast enough. It is driving me nuts!”

Reuters also claimed that – on several occasions – Musk told employees to imagine they had a bomb strapped to their heads in an effort to get them to move faster.
The total number of animal deaths does not necessarily indicate Neuralink is violating regulations or standard research practices.
Many companies routinely use animals in experiments to advance human healthcare, and they face financial pressure to quickly bring products to market.
The animals are typically killed when experiments are completed, often so they can be examined post-mortem for research purposes.
But current and former Neuralink employees say the number of animal deaths there is higher than it needs to be.
The San Francisco-based company had sought approval from the US Food and Drug Administration for the Neuralink project, which has seen scientists develop a tiny implant with more than 3,000 electrodes, attached to flexible threads measuring about the tenth of the size of a hair, and capable of monitoring about 1,000 neurons.
At the time of its launch, Mr Musk said they had three pigs with two coin-sized implants each, and he described them as “healthy, happy and indistinguishable from a normal pig”.
The alleged issues highlighted with Neuralink’s testing have raised questions about the quality of the data generated from experiments – and this could potentially delay attempts to begin trials on humans.
But some employees interviewed by Reuters said the company treated animals quite well when compared with other research facilities – with animals given freedom to roam in what has been likened to a “Monkey Disneyland”.
One former Neuralink staffer recalled Musk saying that he disliked using animals for research but wanted to make sure they were “the happiest animals” while alive.
Mr Musk and other Neuralink executives did not respond to Reuters’ requests for comment.

This Is Us actress Mandy Moore was also forced to leave her home with her children and pets, saying on Instagram they had found temporary refuge with friends.
The actress said: “Trying to shield the kids from the immense sadness and worry I feel.
“Praying for everyone in our beautiful city. So gutted for the destruction and loss. Don’t know if our place made it.”
According to Velvet Ropes, which maps celebrity properties, Matt Damon, Steven Spielberg, Hilary Swank and Sally Field all have homes close to where fires are raging.
Dr Dre, Tyra Banks, Martin Short, Anna Faris, Milo Ventimiglia, Linda Cardellini, Mary McDonnell, Adam Sandler, Miles Teller, and Jennifer Love Hewitt are also said to have houses in affected areas.
In neighbouring Malibu, which was also affected by fires in December, stars including Beyonce and Jay-Z, Kim Kardashian, Lady Gaga and Billie Eilish are said to be among the celebrity residents.
The Palisades blaze has already burnt through nearly 16,000 acres of land, while the Eaton fire, covering over 10,000 acres, has caused the death of five people.
Three other fires, the Hurst fire, Lidia fire and Sunset fire, are all raging as emergency services battle to bring them under control.
Before the service, Mr Trump was also seen shaking hands with former vice president Mike Pence – the first time the pair have been seen in public together since leaving the White House in 2021.
Prior to that, Mr Pence had refused to back Mr Trump’s claim he had won the 2020 election.
Mr Obama and Mr Trump were also seen talking before the service began.
During his eulogy, Mr Biden said Mr Carter taught him the importance of treating “everyone with dignity and respect.”
“To young people, to anyone in search of meaning and purpose, study the power of Jimmy Carter’s example,” the president said. “Character, faith, love – a true patriot.”
Joshua Carter, the former president’s grandson, also said at the service: “He built houses for people who needed homes.
“He eliminated diseases in forgotten places. He waged peace anywhere in the world, wherever he saw a chance. He loved people.”
From 4 January, Mr Carter’s body was carried by a motorcade through Plains, before heading to the Carter Presidential Center in Atlanta.
The former president’s remains were then flown to Maryland and transferred in a ceremony to a hearse, which was carried in a motorcade to the US Navy Memorial in Washington to honour Mr Carter’s service as a lieutenant in the Navy.
He has since been lying in state at the Capitol Building, where the public could pay respects from Tuesday evening through to Thursday morning
Mr Carter’s body will now be returned to his hometown in Georgia for a second service and burial.
There, a private ceremony will be held at Maranatha Baptist Church before another procession through Plains, where supporters are being encouraged to line the streets for the motorcade.
Mr Carter will then be buried on his property next to his late wife, Rosalynn, who died in 2023.
