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 rolling out Robotaxi pilot in SF Bay Area this weekend: report
Similar to the Austin pilot, the Robotaxi rides will reportedly be a paid service.
Tesla is reportedly preparing to launch a Robotaxi pilot program in the Bay Area this weekend, with invites to a select number of customers reportedly being sent out as early as this Friday.
The update was shared in a report from Insider, which cited an internal memo from the electric vehicle maker.
New Robotaxi service launch
According to Insider, the Robotaxi service in the Bay Area is set to launch as soon as Friday. Thus, some Tesla owners in the area should receive invites to use the driverless ride-hailing service. Similar to the Austin pilot, the Robotaxi rides will reportedly be a paid service.
The publication noted that the Robotaxi service’s geofence in its Bay Area launch will be quite large, as it will include Marin, much of the East Bay, San Francisco, and San Jose. This is not surprising as California has long been saturated with Teslas, and it is home to several of the electric vehicle maker’s key facilities.
Unlike the Austin pilot, the Tesla Robotaxi service’s pilot in the Bay Area will use safety drivers seated in the driver’s seat. These drivers will be able to manually take over using the steering wheel and brakes as needed. As per a spokesperson from the California DMV, the agency recently met with Tesla but the company is yet to submit a formal application to operate fully driverless cars.
Tesla Robotaxi expansion
Interestingly enough, Tesla did tease the release of its Robotaxi service to the Bay Area in its second quarter earnings call. While discussing the service, Tesla VP of Autopilot/AI Software Ashok Elluswamy mentioned that the company will initially be rolling out Robotaxis with safety drivers in the San Francisco Bay Area. He did, however, also highlight that the electric vehicle maker is working hard to get government permission to release the service for consumers.
“The next thing to expand would be in the San Francisco Bay Area. We are working with the government to get approval here and, in the meanwhile, launch the service without the person in the driver seat just to expedite and while we wait for regulatory approval,” he stated.

Tesla is ready with a perfect counter to the end of US EV tax credits
Tesla executives have mentioned that these more affordable models would resemble the company’s current lineup.
The United States’ electric vehicle tax credit is coming to an end at the end of the third quarter. Tesla, the country’s leading electric vehicle maker, is ready to meet this challenge with a rather simple but clever counter.
Tesla executives outlined this strategy in the recently held Q2 2025 earnings call.
End of the US EV tax credit
While Elon Musk has always maintained that he prefers a market with no EV tax credit, he also emphasized that he supports the rollback of any incentives given to the oil and gas industry. The Trump administration has not done this so far, instead focusing on the expiration of the $7,500 EV tax credit at the end of the third quarter.
Tesla has been going all-in on encouraging customers to purchase their vehicles in Q3 to take advantage of lower prices. The company has also implemented a series of incentives across all its offerings, from the Cybertruck to the Model 3. This, however, is not all, as the company seems to be preparing a longer-term solution to the expiration of the EV tax credit.
Affordable variants
During the Q2 2025 earnings call, Vice President of Vehicle Engineering Lars Moray stated that Tesla really did start the production of more affordable models in June. Quality builds of these vehicles are being ramped this quarter, with the goal of optimizing production over the remaining months of the year. If Tesla is successful, these models will be available for everyone in Q4.
“We started production in June, and we’re ramping quality builds and things around the quarter. And given that we started in North America and our goal is to maximize production with a higher rate. So starting Q3, we’re going to keep pushing hard on our current models to avoid complexity… We’ll be ready with new, more affordable models available for everyone in Q4.,” Moravy stated.
These comments suggest that Tesla should be able to offer vehicles that are competitively priced even after the EV tax credit has been phased out. Interestingly enough, previous comments from Tesla executives have mentioned that these more affordable models would resemble the company’s current lineup. This suggests that the more affordable models may indeed be variations of the Model Y and Model 3, but offered at a lower price.

Elon Musk reveals Tesla’s next Robotaxi expansion in more ways than one
Tesla Robotaxi is growing in more ways than one. Tesla wants to expand and hopes to reach half the U.S. population by the end of the year.
Tesla CEO Elon Musk revealed the company’s plans for its next expansion of the Robotaxi in terms of both the geofence in Austin and the platform overall, as it looks to move to new areas outside of Texas.
Tesla launched the Robotaxi platform last month on June 22, and has since expanded both the pool of users and the area that the driverless Model Y vehicles can travel within.
The first expansion of the geofence caught the attention of nearly everyone and became a huge headline as Tesla picked a very interesting shape for the new geofence, resembling male reproductive parts.

The next expansion will likely absolve this shape. Musk revealed last night that the new geofence will be “well in excess of what competitors are doing,” and it could happen “hopefully in a week or two.”
Musk’s full quote regarding the expansion of the geofence and the timing was:
“As some may have noted, we have already expanded our service area in Austin. It’s bigger and longer, and it’s going to get even bigger and longer. We are expecting to greatly increase the service area to well in excess of what competitors are doing, hopefully in a week or two.”
The expansion will not stop there, either. As Tesla has operated the Robotaxi platform in Austin for the past month, it has been working with regulators in other areas, like California, Arizona, Nevada, and Florida, to get the driverless ride-hailing system activated in more U.S. states.
Tesla confirmed that they are in talks with each of these states regarding the potential expansion of Robotaxi.
Musk added:
“As we get the approvals and prove out safety, we will be launching the autonomous ride-hailing across most of the country. I think we will probably have autonomous ride-hailing in probably half the population of the US by the end of the year.”
We know that Tesla and Musk have been prone to aggressive and sometimes outlandish timelines regarding self-driving technology specifically. Regulatory approvals could happen by the end of the year in several areas, and working on these large metros is the best way to reach half of the U.S. population.
Tesla said its expansion of the geofence in Austin is conservative and controlled due to its obsession with safety, even admitting at one point during the Earnings Call that they are being “paranoid.” Expanding the geofence is necessary, but Tesla realizes any significant mistake by Robotaxi could take it back to square one.
