Neuralink Expands Human Trials, 12 People Now Using Brain Implants

Elon Musk’s Neuralink announced Tuesday that 12 people worldwide have received its brain implants, marking steady progress in its clinical rollout.

Key Details

  • Patient Numbers: Up from 7 in June, when partner Barrow Neurological Institute confirmed its involvement.

  • Usage Stats: Collectively, patients have logged 2,000 days of implant use and over 15,000 hours of activity, using the device to control both digital and physical tools through thought.

  • Trials Abroad: A new clinical study will launch in the UK, partnering with University College London Hospitals and Newcastle Hospitals.

  • Funding: Neuralink raised $650 million in June to support expansion.

Background

  • Neuralink began human trials in 2024 after overcoming U.S. FDA safety objections that initially blocked approval in 2022.

  • The company’s implants are aimed at restoring movement and communication for people with severe paralysis, representing a major step in brain-computer interface (BCI) technology.

Outlook

  • The trials will help Neuralink test long-term safety, reliability, and potential new medical applications.

  • If successful, the technology could pave the way for broader use cases — from medical rehabilitation to advanced human-computer interaction.

Trump-Musk Clash Triggers Scrutiny Fears Across Tesla, SpaceX, and Other Ventures

Former U.S. President Donald Trump’s call to review subsidies awarded to Elon Musk’s companies has sparked concerns of heightened regulatory scrutiny across the billionaire’s business empire, which spans automotive, space, energy, brain tech, and social media. The threat of government intervention may disrupt operations or stall innovation in several of Musk’s ventures. Here’s a breakdown of the U.S. agencies involved:

National Highway Traffic Safety Administration (NHTSA)
Tesla is under continued investigation by the NHTSA, especially concerning its advanced driver assistance systems. The agency is reviewing incidents involving Tesla’s robotaxi service in Austin, including videos showing vehicles misbehaving in traffic and in adverse weather. These inquiries extend broader probes into Tesla’s Full Self-Driving (FSD) technology, particularly related to safety during poor visibility.

Federal Communications Commission (FCC)
The FCC has begun reviewing its spectrum sharing policies, which could affect SpaceX’s Starlink satellite internet service. SpaceX is seeking new spectrum access to expand satellite coverage, but decades-old limits on signal power remain a barrier. The review could influence future Starlink deployments and broadband expansion goals.

Food and Drug Administration (FDA)
Neuralink, Musk’s brain implant startup, falls under the FDA’s oversight. After an initial rejection due to safety concerns, the FDA granted clearance for clinical trials, which are currently underway in the U.S. Neuralink is also exploring trials in Canada. The FDA will decide if Neuralink’s implants can eventually be marketed.

Environmental Protection Agency (EPA)
The EPA monitors SpaceX’s wastewater output at its Texas launch site and coordinates with other federal agencies under the National Environmental Policy Act. SpaceX’s rocket activities must pass environmental impact assessments to ensure compliance with land, water, and wildlife protection standards.

Federal Aviation Administration (FAA)
In September, the FAA proposed a $633,000 fine against SpaceX for violating licensing requirements before two 2023 launches. The FAA continues to investigate the company’s safety compliance, especially after repeated rocket explosions. Additional restrictions may follow.

Securities and Exchange Commission (SEC)
Musk is facing litigation from the SEC related to his 2022 acquisition of Twitter (now X). The agency has also probed Neuralink’s compliance and transparency, according to a December 2023 letter from Musk’s attorney, posted on X.

Federal Trade Commission (FTC)
The FTC oversees data and privacy protections at Musk’s social media platform, X. The agency is also investigating antitrust allegations, reviewing whether media watchdog groups coordinated an advertiser boycott that Musk claims is illegal.

Regulatory Risk Outlook
Trump’s renewed focus on Musk’s government support could pave the way for increased enforcement or changes to existing subsidies, affecting growth trajectories across his enterprises. With Musk already under the microscope at multiple agencies, the political escalation adds another layer of complexity.

SEC Reopens Probe Into Neuralink Amid Musk’s Legal Battles

The U.S. Securities and Exchange Commission (SEC) has reopened its investigation into Neuralink, the brain-chip startup founded by Elon Musk, according to a letter shared by Musk on social media platform X. The letter, dated December 12, was from Musk’s lawyer, Alex Spiro, and addressed to outgoing SEC Chair Gary Gensler. It revealed that the SEC had issued a 48-hour settlement deadline to Musk regarding his $44 billion acquisition of Twitter (now rebranded as “X”), which could result in charges if Musk does not accept the monetary settlement offered.

The amount of the settlement was not disclosed, and the letter emphasized that Musk and his legal team would not be “intimidated” by the SEC. This latest development follows Musk’s ongoing legal disputes with the agency, including an investigation into his 2022 Twitter acquisition. Last year, lawmakers called for an investigation into Musk’s handling of Neuralink’s brain implants, questioning whether Musk misled investors about their safety, but it remains uncertain how much legal traction the SEC could gain in such actions against the entrepreneur.

Musk, who also leads Tesla and SpaceX, has had a contentious relationship with the SEC. Notably, a federal judge in November dismissed the SEC’s request to sanction Musk for failing to appear in court regarding his Twitter takeover. This is just one of several legal entanglements Musk faces, including a 2018 settlement over misleading tweets about Tesla’s privatization.

Despite the SEC’s renewed interest, Musk’s legal defense, supported by his influence and financial power, may provide significant resistance to any potential actions or regulations targeting his ventures, including Neuralink.
