EXCLUSIVE: Neuralink dragged into humane testing lawsuit – Timeline of Events
Neuralink has been dragged into a lawsuit by the Physicians Committee for Responsible Medicine against the University of California at Davis. The lawsuit, which is amended from its initial filing date of May 2021, seeks to have UC Davis release images and video of inhumanely-treated test subjects, including monkeys, who died after participating in some trials of Neuralink-sponsored research for the development of neural interface implant devices. We have put together an exclusive timeline of events based on interviews and an examination of over 700 pages of documents that UC Davis was required to turn over to the PCRM.
The Physicians Committee for Responsible Medicine (PCRM) is a nonprofit organization with more than 17,000 doctor members. It filed a formal complaint with the United States Department of Agriculture today, claiming UC Davis and Neuralink staff violated the federal Animal Welfare Act related to experiments performed on 23 monkeys. Neuralink paid more than $1.4 million to UC Davis to carry out the experiments.
The PCRM said in a press release that Neuralink and the University “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.”
In an exclusive interview with Teslarati earlier today, Jeremy Beckham, MPA, MPH, PCRM’s Research Advocacy Coordinator, said that the lawsuit really intends to open up “basic facts about what Neuralink testing did to the animals.” Beckham said monkeys had their brains mutilated in the experiments. Veterinary records, which were shared with Teslarati by the PCRM, show that UC Davis and Neuralink staff performed invasive and deadly experiments on monkeys to assess the effectiveness of the Neuralink device. The letter sent from the PCRM to the USDA earlier today gives several graphic descriptions of how the test animals were treated.

Neuralink details humane animal treatment during Link v0.9 testing
One animal, known as “Animal 6,” was a 6-year-old macaque monkey who was killed on January 16, 2019. The letter states that, on October 10, 2018, implanted electrodes “were placed using an investigational robot,” then, “attached to skull using titanium implant screws.” The location of the screws began to become infected, according to the letter. By January 14th, “Animal 6” had started to pick at the infected area. Staff euthanized the monkey two days later.
Timeline of Events
PCRM has been working to clarify the situation since September 2020, but a more descriptive timeline of events would clarify how Neuralink, UC Davis, and the PCRM have all combined into this issue.
- May 2017 – The University of California at Davis and Neuralink sign and agree to Non-Disclosure Agreements regarding testing.
- September 2017 – UC Davis and Neuralink officially begin their collaboration to carry out primate experiments at UC Davis facilities. The goal is to develop a brain-machine interface.
- July 2018 – “Animal 4,” an 11-year-old macaque monkey is killed in the Neuralink/UC Davis experiments, according to the complaint. The monkey was “on anti-depressants and had chronic diarrhea and poor appetite.” Additionally, the monkey was observed as “lethargic” and “depressed,” and hunched and passed bloody diarrhea. The monkey eventually died in a deadly procedure on July 20th.
- Also in July 2018 – “Animal 12,” approximately 7-years-old, undergoes a craniotomy and electrode insertion procedure. Records show the animal had “severe clinical adverse effects following the implantation, had poor stool quality, was not eating, and had an eye infection.” Records abruptly ended on July 30th.
- September 2018 – “Animal 21,” a 7-year-old female macaque undergoes an “electrode insertion survivability” procedure using “investigational robotics.” The animal was observed with adverse side effects the following day, including vomiting, gasping, retching, and had little interaction with their environment and observers. The animal was euthanized and had signs of “Bioglue,” an unapproved adhesive, covering the brain.
- December 2018 – “Animal 15,” a 7-year-old female macaque undergoes a craniotomy and recording device implantation. Following the surgery, the area became infected and bloody. The animal was euthanized on March 21, 2019. The performed necropsy shows “remnant electrode threads.”
- January 2019 – “Animal 6,” a 6-year-old macaque monkey is killed as a part of the “experimental design.” Electrodes were secured by screws drilled into the monkey’s skull, and lab staff were forced to “frequently clean” the eroding skin near the monkey’s implant site.
- March 2019 – “Animal 11” is killed at approximately 11-years-old during a terminal procedure. The monkey had an implant placed on the head or brain on December 3rd, 2018, and began experiencing symptoms like a weakened appetite and missing fingers and toes, possibly caused by self-mutilation.
- January 2020 – “Animal 5,” another macaque monkey is killed “inadvertently” by an anticonvulsant. He showed signs of significant weight loss and alopecia.
- July 2020 – Neuralink’s Elon Musk announces that the company will hold an event on August 28th, 2020, to display the progress of the V0.9 device. “Will show neurons firing in real-time on August 28th. The matrix in the matrix,” Musk said in a Tweet.
- Also in July 2020 – Neuralink receives a ‘breakthrough device’ designation from the FDA in July, and the company is working with the agency to make the technology as safe as possible.
- August 2020 – Neuralink unveils the v0.9 device, displaying healthy and functioning pigs. Musk delivers a presentation on the new device, showing the simplified product Neuralink has developed. “It’s like a FitBit in your skull with tiny wires,” Musk half-joked. “I could have it right now and you wouldn’t even know. Maybe I do!” The device is said to be installed without general anesthesia. There will be no bleeding, and no noticeable damage after the device is implanted.
- September 2020 – The PCRM files a California Public Records request, wishing for information regarding UC Davis trials of the Neuralink device. 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.”
- October 2020 – “Animal 10,” an 8-year-old macaque monkey, is shipped to Neuralink’s facility in Fremont. The monkey has significant hair loss, had lesions from “unspecified traumas,” and was exhibiting self-mutilating behavior.
- November 2020 – Neuralink severs ties with UC Davis on November 11. Neuralink then moves seven of the remaining monkeys to its facility in Fremont, California. Beckham said that records show 15 of the 23 monkeys used in the research died or were euthanized at UC Davis. The final monkey’s situation is unclear, but it is possible the animal was reassigned to a different project at UC Davis, Beckham said.
- April 2021 – Neuralink releases a YouTube video of “Pager the Monkey” allegedly playing video games with a wireless neural interface. The video features a nine-year-old Macaque named Pager playing “MindPong” while utilizing a Neuralink device.
- May 2021 – PCRM sues the University of California Davis under the California Public Records Act (CPRA) for not releasing records in September 2020. Before the suit reaches a judicial decision, Counsel for the University of California agrees to release 700 pages of information.
- October 2021 – University of California’s General Counsel turns over files including animal testing records and veterinarian reports to PCRM. More than 700 pages of records are turned over.
- February 2022 – PCRM files a separate complaint with the U.S. Department of Agriculture that alleges the information the organization has already received reveals evidence of violations of Federal Animal Welfare laws.
Moving Forward
Beckham maintains that the main point of the newest filing is to have UC Davis turn over photographs and videos that reveal the inhumane treatment of the animals due to the experiments. There are monkeys convulsing, vomiting, and dying in these labs,” Beckham said. “People want to step in line for the first human trials, and they should see this before they commit to that,” he told Teslarati. Neuralink was set for human trials this year, Musk said last year.
Beckham said that these complaints can take a while to work through the legal system. “In my years of being involved with humane testing litigation, I know that these things can take some time. Maybe up to a year,” he said. “It also depends how much they want to fight back.”
Neuralink did not immediately respond to our requests for comment.

Tesla parked 50+ Cybercabs outside its Texas Factory with some crash tested
Dozens of Tesla Cybercabs have been spotted at Giga Texas crash testing facility ahead of launch.
Drone footage captured by longtime Giga Texas observer Joe Tegtmeyer shows over 50 units of Tesla Cybercab at the Austin factory campus, including several units clustered by Tesla’s on-site crash testing facility.
The outbound lot at Gigafactory Texas sits just outside the factory exit and serves as the primary staging area where finished vehicles are held before being loaded onto transport carriers or dispatched for validation testing. On any given day, the lot holds a mix of Model Y and Cybertruck units alongside the growing Tesla Cybercab fleet, as can be seen in the drone footage captured by Joe Tegtmeyer.
Roughly 50 Cybercab units are visible across the campus, parked in tight organized rows. Most of the units visible still carry steering wheels and pedals, temporary additions Tesla included to satisfy current safety regulations while the vehicles accumulate real-world data ahead of full regulatory approval for a steering wheel-free design. Tesla operates dedicated Crash Labs at both its Giga Texas and Fremont facilities that are purpose-built for controlled structural crash tests. Historically, automakers begin intensive crash testing roughly one to two months before volume production kicks off. The Cybertruck followed almost exactly that pattern. The Cybercab appears to be on the same track facility that we first saw back in October 2025. The first production Cybercab rolled off the Giga Texas line on February 17, 2026. Volume production is now targeted for April. Musk previously wrote on X that “the early production rate will be agonizingly slow, but eventually end up being insanely fast,” and separately stated Tesla is targeting at least 2 million Cybercab units per year. Commercial robotaxi service in Austin is targeted for late 2026.

Tesla 2026 Spring Update drops 12 new features owners have been waiting for
Tesla announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.

Tesla launches new Model Y interior option
Produced at Gigafactory Shanghai, the update applies to all five-seat Premium Model Y configurations and started being seen on customer deliveries this week. The move marks the first major interior refresh for the compact crossover since its global debut.
Tesla has rolled out a striking new interior choice for its best-selling Model Y in China, replacing the long-familiar white cabin with a fresh option: Zen Grey.
Produced at Gigafactory Shanghai, the update applies to all five-seat Premium Model Y configurations and started being seen on customer deliveries this week. The move marks the first major interior refresh for the compact crossover since its global debut.
The Zen Grey interior swaps the classic black-and-white contrast for a softer, more unified palette. Seats, door panels, and center console trim now feature a warm light-grey tone that covers far more surface area than before.
Previously, black accents on the console, door handles, and lower dashboard are now color-matched in the same pebbled vegan leather, creating a brighter, less clinical cabin.
Tesla describes the material as durable and easy to maintain while delivering a noticeably more premium feel. Early photos and videos from Chinese owners show the new shade reflecting natural light beautifully, giving the spacious Model Y an even airier, more inviting atmosphere without sacrificing the minimalist design customers expect:

— TESLARATI (@Teslarati) April 13, 2026
The change is not an added-cost upgrade but a direct replacement for the discontinued white interior on Shanghai-built vehicles. Customers configuring a new Model Y in China, Hong Kong, or Macau now see Zen Grey as the default light-colored choice.
The update also flows to export markets supplied by Giga Shanghai, including Australia, New Zealand, South Korea, Japan, and the Philippines. Tesla has used its Chinese factory as an innovation hub before, and executives appear to be testing broader appeal with this subtler, warmer tone that avoids the high-maintenance reputation sometimes associated with bright white leather.
Beyond the interior, the refreshed Model Y from Shanghai includes minor exterior tweaks such as blacked-out badges on some trims and optional dark 20-inch wheels.
These changes arrive as Tesla faces stiff competition from domestic EV makers in its largest market. By refreshing the Model Y’s cabin without raising prices, the company is signaling continued commitment to value and constant improvement.
With over 1.2 million Model Y units already on Chinese roads, the Zen Grey launch gives existing owners a fresh talking point and new buyers another reason to choose Tesla. As deliveries ramp up this month, the updated interior is expected to become the dominant light-colored choice across the Asia-Pacific region.
Tesla has not yet confirmed whether the Zen Grey will reach Fremont, Austin, or Berlin-built Model Ys, but Shanghai’s track record suggests the option could spread quickly if customer feedback remains strong.
