A nonprofit physicians organization has sent a letter to top
government officials alleging that Elon Musk made false claims that
at least a dozen monkeys who died during Neuralink brain implant
experiments were “terminally ill,” according to news.
The Physicians Committee for Responsible Medicine (PCRM), after
obtaining documents via a public records request and lawsuit,
formerly alleged that Neuralink had violated federal animal welfare
laws and killed at least 1,500 animals in its brain implant
experiments — sparking a federal investigation that remains ongoing. Sign and share PCRM's alert:

Those alleged victims included at least a dozen macaques who
reportedly suffered and ultimately died from complications,
including brain swellings and infections.
Musk took to his platform X, formerly known as Twitter, in September
to deny those allegations, instead claiming that the monkeys who
died all were “terminally ill.”
Neuralink and Musk did not respond to media inquiries.
But in the post from Sept. 10, which has since been archived on the
Way Back Machine, Musk wrote, “No monkey died as a result of a
Neuralink implant. First our early implants, to minimize risk to
healthy monkeys, we chose terminal monkeys, close to death already.”
The letter from PCRM, which asks officers with the U.S. Securities
and Exchange Commission to investigate and penalize Musk and
Neuralink, provides examples of documented animal suffering that
appear to directly contradict those claims.
“Public records obtained by the Physicians Committee reveal that at
least 12 young, previously healthy monkeys were euthanized by
Neuralink as a direct result of the company’s implant,” the letter
reads. “The animals deaths and the reasons for their deaths relate
directly to the safety and marketability of the brain-computer
interface Neuralink is developing, and thus it is critical that the
company provide investors with factually accurate information.”
The letter notes that captive macaques typically can live to be
between 25 and 40 years old and that at least 10 of the 12 monkeys
who died in the Neuralink experiments were less than 8 years old —
meaning they hadn’t even reached adulthood.
The letter summarizes the deaths of four monkeys, including “Animal
22,” a 6-year-old male macaque whose implant screws reportedly
loosened to the point where lab staff could lift them out due to a
“purely mechanical” failure.
Meanwhile, Neuralink has announced that the Food and Drug
Administration (FDA) has approved human clinical trials of the brain
implants and that the company is actively recruiting people who
suffer from paralysis, with an aim to see if they can control a
computer keyboard or cursor with their thoughts.
It’s unknown how many people may enroll in the study, according to
Reuters, which also reported that Neuralink initially had requested
10 people but was negotiating a lower number with the FDA.
