Elon Musk‘s brain-computer interface company, Neuralink, has been making waves with groundbreaking developments and recent funding milestones. Founded in 2016, the company aims to revolutionise the interface between the human brain and external devices, and its recent achievements and controversies have brought the company into the spotlight.
Funding and Valuation
Neuralink‘s journey has been fuelled by substantial investments, with the company raising an additional $43 million in a recent venture capital round. Led by Peter Thiel’s Founders Fund, the funding round increased the previous tranche from $280 million to an impressive $323 million in early August. While the company has not officially disclosed its valuation in recent times, reports from June suggested that the company had achieved a valuation of approximately $5 billion after privately executed stock trades.
Technological Advancements
At the core of Neuralink’s innovations is a sewing machine-like device designed to implant ultra-thin threads directly into the brain. These threads are not merely passive; They connect to a custom-designed chip equipped with electrodes capable of reading data from groups of neurons. The unique aspect of the technology lies in its wireless implementation and the increased number of electrodes, setting it apart from conventional brain-signal-reading implants.

Human Trials and Regulatory Approval
Neuralink’s journey is not confined to the laboratory, as the company takes a significant step towards practical applications. In September, they announced the recruitment of its first test subjects for human trials, aimed at assisting individuals with paralysis in controlling external devices through their thoughts. The PRIME Study, an acronym for Precise Robotically Implanted Brain-Computer Interface, will assess the safety of Neuralink’s implant (N1) and surgical robot (R1), providing crucial insights into the functionality of their wireless brain-computer interface.
This move towards human trials has received approval from the independent institutional review board and the first hospital site. The ambitious goal of enabling people with paralysis to control external devices through their thoughts underscores Neuralink’s commitment to addressing real-world challenges through advanced neurotechnology and soon-to-be AI Doctors.
Workplace Culture and Ethical Concerns
However, Neuralink’s journey has not been without its challenges. The company has faced criticism for its workplace culture, as former employees anonymously described a “Culture of blame and fear”. Reports highlight instances where Elon Musk encouraged junior employees to communicate issues and complaints directly to him, potentially undermining the established management structure. Such challenges have reportedly led to a high turnover of founding scientists, reflecting internal conflicts and a clash between ambitious timelines and the incremental pace of scientific progress.
Animal Welfare Controversy
Neuralink has also found itself embroiled in controversies related to animal welfare. Allegations surfaced regarding the mistreatment of monkeys involved in testing the hardware, including claims of psychological distress and chronic infections resulting from rushed testing and electrode installations.
The company underwent a federal investigation by the U.S. Department of Agriculture (USDA), which ultimately concluded that there was “No evidence” of animal welfare breaches in the startup’s trials, aside from a previously self-reported incident from 2019. However, the Physicians Committee for Responsible Medicine (PCRM) disputed these findings, adding to the ongoing ethical debate surrounding the company’s research practices.

SEC Investigation and Transparency Concerns
In a recent turn of events, U.S. lawmakers have called for an investigation by the Securities and Exchange Commission (SEC) into Neuralink. The request stems from concerns about the omission of details regarding the deaths of at least a dozen animals that underwent surgical procedures involving Neuralink’s implants. This development raises questions about transparency in the company’s reporting and adds a layer of scrutiny to Neuralink’s operations.
The Road Ahead
As Neuralink continues its quest to unlock the mysteries of the human brain and redefine the possibilities of human-machine interaction, the world watches with a mixture of anticipation and scrutiny. The outcomes of human trials, the resolution of ethical concerns, and the findings of any regulatory investigations will shape Neuralink’s narrative and contribute to the broader dialogue on the ethical and social implications of neurotechnology.
All in all, Neuralink represents a captivating venture that transcends the boundaries of conventional neuroscience and technology. As the company charts its course into uncharted territory, the world awaits a future where the seamless integration of technology and the human mind becomes a reality, transforming lives in ways previously deemed unimaginable.
