Neuralink has responded to claims of inhumane treatment during the animal testing phases of various company products, stating that animal welfare is a priority. “At Neuralink, we are absolutely committed to working with animals in the most humane and ethical way possible.”
Last week, reports surfaced of a lawsuit against the University of California at Davis from the Physicians Committee of Responsible Medicine (PCRM). The suit claims that the facility “failed to provide dying monkeys with adequate veterinary care, used an unapproved substance known as “Bioglue” that killed monkeys by destroying portions of their brains, and failed to provide for the psychological well-being of monkeys assigned to the experiment.” Earlier today, Teslarati reported an extensive timeline of events from the beginning of the partnership between UC Davis and Neuralink to the most recent developments, which include the potential of videos and photographs of the animals involved in the testing. Teslarati obtained several copies of veterinarian records from autopsies of some monkeys used in the experiments.
Neuralink is now responding to the various claims of animal abuse in a lengthy statement that outlines the past, present, and future developments of Neuralink trials. The company maintains that all animals are treated respectfully and ethically.
EXCLUSIVE: Neuralink dragged into humane testing lawsuit – Timeline of Events
Neuralink ended its partnership with UC Davis in November 2020, just two months after PCRM sent a California Public Records request for information regarding the Neuralink trials. The request is eventually denied in accordance with California State Code 6255(a), which says that the Agency “shall justify withholding any record by demonstrating that the record in question is exempt under express provisions of this chapter or that on the facts of the particular case the public interest served by not disclosing the record clearly outweighs the public interest served by disclosure of the record.”
-->Neuralink took several of the monkeys back to its testing facilities in Northern California for in-house experiments. “Once construction of our in-house facility was completed, we were able to bring some unimplanted macaques from UC Davis with us to Neuralink. This included Pager, who would later be implanted with our Neuralink device and go on to achieve outstanding brain-computer interface performance, while freely behaving and unrestrained, as demonstrated in the Monkey MindPong video,” the company’s official response said. “While the facilities and care at UC Davis did and continue to meet federally mandated standards, we absolutely wanted to improve upon these standards as we transitioned animals to our in-house facilities.”
Neuralink says that “no injuries occurred at any time to animals housed at UC Davis” while the tests were ongoing. The company admits several animals were euthanized for research purposes, but they were done under controlled circumstances:
“The initial work from these procedures allowed us to develop our novel surgical and robot procedures, establishing safer protocols for subsequent survival surgeries. Survival studies then allowed us to test the function of different generations of implanted devices as we refined them towards human use. The use of every animal was extensively planned and considered to balance scientific discovery with the ethical use of animals. As part of this work, two animals were euthanized at planned end dates to gather important histological data, and six animals were euthanized at the medical advice of the veterinary staff at UC Davis. These reasons included one surgical complication involving the use of the FDA-approved product (BioGlue), one device failure, and four suspected device-associated infections, a risk inherent with any percutaneous medical device. In response we developed new surgical protocols and a fully implanted device design for future surgeries.”
Interestingly, PCRM said in a press release that “BioGlue” is an unapproved substance. FDA documents obtained by Teslarati show that BioGlue was approved for use in 2001, but the agency also included a warning of potential side effects when BioGlue is applied to the phrenic nerve. Application of BioGlue to this area in animals can cause acute nerve injury. Additionally, “BioGlue application to the surface of the heart can cause coagulation necrosis that extends into the myocardium, which could reach underlying conduction tissue and may cause acute, focal sinoatrial node degeneration,” the documents said. Five pigs were tested during initial animal experimentation while the FDA was determining BioGlue’s safety. All five pigs survived to the designated observation time.
Neuralink details humane animal treatment during Link v0.9 testing
-->Presently, the animals involved in Neuralink testing are housed at the company’s 6,000-square-foot facility that houses farm animals and rhesus macaques. The company takes care of the animals from the time they enter the facility to the time they leave, even detailing an animal’s process for “retirement:”
“Can we release the animals that regularly choose not to participate or who have completed their contribution to the study? Yes! We opted to retire animals at the conclusion of their projects. We retired several macaques to a sanctuary last March because they consistently chose to spend their day swimming in their pools, foraging, and relaxing in their hammocks rather than attending the game we presented to them. Their brand new enclosures and sanctuary costs were fully funded by Neuralink.”
Moving forward, Neuralink says it is always working to improve the current standards for animal well-being. “We also look forward to a day where animals are no longer necessary for medical research. Yet our society currently relies on medical breakthroughs to cure diseases, prevent the spread of viruses, and create technology that can change how people are able to interact with the world. However, if animals must be used in research in the meantime, their lives and experiences should be as vital and naturalistic as possible. We will always strive to surpass the industry standard and never stop asking ourselves: “Can we do better for the animals?”, and never forget it is a privilege to work with animals in research. It is our responsibility as caretakers to ensure that their experience is as peaceful and frankly, as joyful as possible.”

Tesla is launching a crazy Full Self-Driving free trial, which will enable owners who have not purchased the suite outright to try it for 30 days.
There are a handful of stipulations that will be needed in order for you to qualify for the free trial, which was announced on Thursday night.
Tesla said the trial is for v14, the company’s latest version of the Full Self-Driving suite, and will be available to new and existing Model S, Model 3, Model X, Model Y, and Cybertruck owners, who will have the opportunity to try the latest features, including Speed Profiles, Arrival Options, and other new upgrades.
🚨 Tesla is launching a free 30-day trial of Full Self-Driving in North America for owners.
It includes every model, but you need v14.2 or later, and you cannot have already purchased the suite outright. https://t.co/8CNmxxOkVl
— TESLARATI (@Teslarati) November 27, 2025
You must own one of the five Tesla models, have Full Self-Driving v14.2 or later, and have an eligible vehicle in the United States, Puerto Rico, Mexico, or Canada.
The company said it is a non-transferable trial, which is not redeemable for cash. Tesla is reaching out to owners via email to give them the opportunity to enable the Full Self-Driving trial.
Those who are subscribed to the monthly Full Self-Driving program are eligible, so they will essentially get a free month of the suite.
Once it is installed, the trial will begin, and the 30-day countdown will begin.
-->Tesla is making a major push to increase its Full Self-Driving take rate, as it revealed that about 12 percent of owners are users of the program during its recent earnings call.
Tesla CFO Vaibhav Taneja said during the call:
“We feel that as people experience the supervised FSD at scale, demand for our vehicles, like Elon said, would increase significantly. On the FSD adoption front, we’ve continued to see decent progress. However, note that the total paid FSD customer base is still small, around 12% of our current fleet.”
Earlier today, we reported on Tesla also launching a small-scale advertising campaign on X for the Full Self-Driving suite, hoping to increase adoption.
Tesla Full Self-Driving warrants huge switch-up on essential company strategy
-->It appears most people are pretty content with the subscription program. It costs just $99 a month, in comparison to the $8,000 fee it is for the outright purchase.
Tesla Full Self-Driving has warranted a huge switch-up on an essential company strategy as the automaker is hoping to increase the take rate of the ADAS suite.
Unlike other automotive companies, Tesla has long been an outlier, as it has famously ditched a traditional advertising strategy in favor of organic buzz, natural word-of-mouth through its production innovation, and utilizing CEO Elon Musk’s huge social media presence to push its products.
Tesla has taken the money that it would normally spend on advertising and utilized it for R&D purposes. For a long time, it yielded great results, and ironically, Tesla saw benefits from other EV makers running ads.

However, in recent years, Tesla has decided to adjust this strategy, showing a need to expand beyond its core enthusiast base, which is large, but does not span over millions and millions as it would need to fend off global EV competitors, which have become more well-rounded and a better threat to the company.
-->In 2024 and 2025, Tesla started utilizing ads to spread knowledge about its products. This is continuing, as Full Self-Driving ads are now being spotted on social media platforms, most notably, X, which is owned by Musk:

Interestingly, Tesla’s strategy on FSD advertising is present in Musk’s new compensation package, as the eleventh tranche describes a goal of achieving 10 million active paid FSD subscriptions.
Full Self-Driving is truly Tesla’s primary focus moving forward, although it could be argued that it also has a special type of dedication toward its Optimus robot project. However, FSD will ultimately become the basis for the Robotaxi, which will enable autonomous ride-sharing across the globe as it is permitted in more locations.
-->Tesla has been adjusting its advertising strategy over the past couple of years, and it seems it is focused on more ways to spread awareness about its products. It will be interesting to see if the company will expand its spending even further, as it has yet to put on a commercial during live television.
We wouldn’t put it out of the question, at least not yet.
Tesla was nice enough to hook us up with the new Model Y “Standard” trim for a few days, and while we’ll be sure to fill you in on the full experience in the coming days, there are a lot of differences we noticed right off the bat, which make the ownership experience different from the “Premium” configuration level.
I purchased a Model Y Long Range All-Wheel-Drive back in August and took delivery just two weeks later. Through the first three months of owning my car, I’ve come to love so many things about the Tesla experience.
I traded my ICE vehicle for a Tesla Model Y: here’s how it went
However, I was interested in experiencing the affordable trim and seeing whether I would miss any of the voided features of the “Premium” Model Y.
Through the first 24 hours, here are my first impressions of the Model Y Standard as a Premium trim level owner:
-->Overall Aesthetic
The lack of a light bar is not something that is a dealbreaker. In fact, I would argue that the Model Y Standard’s more traditional headlight design is just as pleasing from an aesthetic standpoint.
The car is great looking from top to bottom; there are not a substantial number of differences besides the lack of a lightbar on both the front and the back of the car.
Overall, it is a very sleek vehicle, but the major changes are obviously with the interior.
Interior Changes
This is where the big differences are, and some of the things I’ve gotten used to in the Premium are not included. If I didn’t have a Premium Model Y already, I’m not sure I’d miss some of the things that are not present in the Standard trim, but I believe I’d get annoyed with it.
First impressions:
✅ Interior is excellent. I definitely miss the additional storage already that is available in my Premium. I could definitely get over it though
✅ Noticeable step down in sound system. Long Time by Boston absolutely cranks in the Premium; it’s still very… https://t.co/JNWvxTd8p1

Storage
The Premium has a large storage compartment between the cupholders and the wireless charger, which is not present in the Standard trim. Instead, it is more like the Cybertruck, as there is a pass-through and floor storage.
I think that the pass-through is nice, but the additional storage is something I take advantage of, especially as someone who films Full Self-Driving videos, which requires hauling mounts, GoPros, and other accessories.
-->The sleekness of the Premium trim is also something I prefer; I really enjoy having the ability to close those compartments and cover the cupholders.
Obviously, this is a really trivial issue and not something that is substantially impactful from an ownership experience. If I weren’t already an owner, I am not sure I’d even have something to complain about.
Material Differences
The Premium trim seats are completely Vegan Leather, which I really do like, even as someone who doesn’t really love leather seats due to their temperature dependency.
The Standard trim features a Textile and Vegan hybrid, which has half of the seat a different material than the other.
The material is very similar to what I had in my previous car, a Bronco Sport. It was very durable, easy to clean, dried quickly, and hid a lot of things that leather does not, like oils from your skin, which constantly require attention to keep your interior looking fresh.
-->The wireless charger is also a different material, as the Premium features an Alcantara material on that. The Standard has a rubberized and textured backing, which looks good, too. They’re both more than suitable.
Other Missing Features
The Standard lacks a few minor things, most noticeably is the ambient lighting. The biggest change, however, and something I really miss, is the glass roof.
A lot of people told me that when I got my Model Y, I wouldn’t even notice the glass roof after a few weeks. That could not be further from the truth. I look out of it all the time, and it’s one of my family’s favorite parts of the car.
My Fiancè and I really love parking and watching Netflix when we pick food up, especially when it’s raining, because the glass roof gives such a great view.
We also loved it as Fall arrived, because it was great to look at the foliage.
-->Buy the Tesla.

Bigger Differences
There are also a handful of very noticeable differences from the overall cabin experience, especially with the sound system.
Much Weaker Sound System
The Model Y Standard has just 7 speakers and 1 amp, with no subwoofer. This is a significant step down from the 13-15 speakers in the Premium Long Range AWD Model Y, the 2 amps it comes with, and 1 subwoofer in the trunk.
-->I usually like to listen to Long Time by Boston to test out a sound system, and it was noticeably weaker in the Standard. It was missing a big portion of the umph that is provided by the Premium’s sound system.
Cabin Noise
It feels like the Cabin Noise is definitely more noticeable in the Standard, which is something I really love about my Model Y. It is able to dampen so much road noise from louder cars, and I don’t feel as if it is very quiet in the Standard.
This is perhaps the biggest make-or-break for me with this car. I truly have been spoiled by how quiet the cabin is in the Premium, and it’s due to the lack of acoustic-lined glass in the Standard.
I will be doing a more in-depth review of the Model Y Standard, especially with ride quality, later this week.
