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.

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 Theater might be getting plenty more streaming platforms
The in-car Tesla Theater is among the most unique features available within the cars. When charging, parked, camping, or just hanging out, vehicle occupants can access a variety of streaming platforms on the large center screen, helping keep them entertained during downtime.
However, the Theater might be getting plenty more streaming platforms, something that owners have requested for some time.
Tesla owners recently discovered that visiting Apple TV in the vehicle browser can launch a fullscreen interface that looks and behaves like a dedicated application rather than an ordinary webpage:
Today I learned that if you go to Apple TV in the Tesla browser, it will open up an actual Apple TV app, fully functional. Not just the site.
Apparently there are more apps than just the few that show on the apps page. pic.twitter.com/os1Ypfm4JR
— Jason W (@jmwilt21) August 20, 2026
The experience drops the usual address bar and browser chrome, presenting catalogs, continue watching rows, and playback controls in the same window Tesla Theater already uses for its listed services. Independent testers soon found similar treatment for HBO Max, Paramount+, Peacock, Disney+, and Prime Video when those sites are opened from the car browser.
This shift is a plausible early signal that Tesla is widening Theater support without a formal software note. Theater has long been a set of web views rather than native applications, so recognizing extra domains and stripping the browser frame is a small server-side change that can expand the catalog quickly.
Owners still lack permanent Theater icons for the newly recognized services, and video remains limited to Park, yet the smoother launch is a meaningful step toward a broader lounge while charging.
Tesla Theater arrived with software version 10 in September 2019. The first video services were Netflix, YouTube, and Hulu, available only while parked and originally tied to WiFi. Spotify arrived in the same era as music rather than Theater video. Disney+ joined officially in July 2021 with the 2021.24 update, giving owners another major catalog on the center screen. Twitch and TikTok later appeared among the default Theater tiles, and Tesla Tutorials remained a persistent educational tile.
Not every addition stayed put. In December 2023, a Holiday software build removed the Disney+ tile for many United States owners after a public dispute involving advertising on X. Hulu stayed visible even though Disney owned it. Visiting disneyplus.com in the browser often restored the tile, which suggested the removal was a recognition list change rather than a complete block. Owners have also reported occasional blank Theater grids after updates, usually fixed by language toggles, resets, or later firmware.
Tesla axes Disney+ from vehicles with Musk-Iger rivalry, but there’s a workaround
Code archives from 2024 listed many unused source names, including Apple TV and Prime Video, that never became official icons, which now looks like groundwork for the current fullscreen browser behavior.
Now that this hint toward an expanded Theater experience has been recognized, Tesla could follow through with these additional shortcuts as a sign that more streaming platforms are available in Teslas than ever before.

Tesla Semi’s biggest adoptee gives an update on production timeline
Tesla recently received its largest order for the all-electric Semi from Einride, a Swedish transport service, for 500 units, a groundbreaking invoice to receive before the first deliveries begin.
Even more remarkable, Einride CEO Roozbeh Charli said in a recent interview that he expects his company to take delivery of all 500 — the entire order — before the end of 2027. He even expects to have 75 Tesla Semi units in the Einride fleet before the end of this year.
🚨 Einride CEO Roozbeh Charli on the Tesla Semi partnership:
“If we start with the Amazon announcement that we did earlier this year, that was on the back of having gone through a proving period together with them and proving out our technology. Then we took that next step in… pic.twitter.com/oazkXjwoig
— TESLARATI (@Teslarati) August 28, 2026
Charli said the Tesla partnership was part of a broader push, along with its earlier partnership with Amazon. Einride is assisting Amazon with the use of its Saga AI platform, which helps eliminate questions about budgeting and forecasting for logistics companies.
The Semi, as well as Tesla’s production and subsequent delivery of the units to Einride, will help the company “to have a good supply of vehicles that we can deploy on the [Saga AI] platform,” Charli said. “Tesla is also a relationship we’ve had for a while, and as the Tesla Semi deliveries are firming up, we decided to do a larger commitment to that and deploy that on our platform.”
In its initial announcement, Einride said it anticipated taking delivery of the trucks over the next two years, but now it appears the company is expecting all 500 units within the next 16 months.
Built at a dedicated factory in Sparks, Nevada, the Tesla Semi has been perhaps the biggest and most intensive testing process the company has ever had for a single vehicle model. For the past several years, Tesla has been working with many companies, most notably Frito-Lay and PepsiCo, to gain knowledge on the performance on regional routes.
Tesla plans to launch the Semi officially on September 24, five months after production started ramping.
Additionally, drivers have said they are happy about the Semi’s performance and that its numerous safety and productivity features have made their jobs and routes much easier.

Tesla Cybercab uses a unique strategy for picking up the right rider
Tesla Cybercab is using a unique strategy for picking up the correct rider, which is a crucial part of ride-hailing to ensure people end up in the right place and are charged the correct price.
Cybercab will utilize an RGB strip in its front light bar that will illuminate in a variety of different colors to mark itself.
This identifying mark will also appear in the Robotaxi app, giving riders in the same location a notable distinction in an effort to avoid any confusion regarding who should get in each vehicle.
🚨 Tesla is using different light bar colors to help riders understand which vehicle is theirs
Pretty cool strategy pic.twitter.com/eGMpEMeRpc
— TESLARATI (@Teslarati) August 27, 2026
Other ride-hailing services use similar strategies: Lyft and Uber rides are recognizable through driver identity, vehicle type and color, as well as license plate. Waymo will display the rider’s initials on top of the vehicle, letting them know that the specific vehicle for them has arrived.
Tesla’s strategy is unique and interesting, but there are some flaws. Cybercab’s main purpose is aimed toward being an autonomous ride for all, including those who have disabilities like being blind or even color blind.
Tesla will likely have something in the pipeline for those who cannot see colors or have limited vision. There will definitely be multiple ways to identify which vehicle is the one that “you” specifically ordered.
Cybercab is set to start giving public rides next Thursday, September 3, in Austin, as it announced a dedicated event last week and invited many members of the Tesla community.
Additionally, members of the public will be invited as well. Tesla has been offering employee rides in Cybercab for nearly two months.
