Neuralink, Elon Musk’s pioneering startup, revealed on Wednesday that a portion of its brain implant experienced malfunction following its deployment in a human patient for the inaugural time.
The company, dedicated to developing brain-computer interfaces (BCIs) aimed at enabling individuals with paralysis to control external technology through neural signals, deployed its revolutionary system, the Link. This BCI, boasting 1,024 electrodes distributed across 64 ultra-fine threads, thinner than a human hair, holds promise for transforming the landscape of neural technology, as per Neuralink’s website.
In January, Neuralink conducted the landmark implantation procedure on a 29-year-old patient named Noland Arbaugh, as part of a safety evaluation study. Subsequently, a live video stream featuring Arbaugh utilizing the BCI in March showcased encouraging results, with Neuralink lauding the surgery’s success in an April blog post.
However, in the aftermath, Neuralink encountered setbacks, with several threads retracting from Arbaugh’s brain in the ensuing weeks, diminishing the effectiveness of the electrodes and impeding the company’s ability to assess the Link’s performance.
To address these challenges, Neuralink disclosed modifications to the recording algorithm, enhancements to the user interface, and refinements in signal translation techniques to improve cursor movements. Although Neuralink contemplated removing the implant, the issue has not posed an immediate safety risk to Arbaugh, according to The Wall Street Journal, which first reported the problem. Neuralink issued its blog post in response to queries from the Journal.
Despite setbacks, Arbaugh continues to utilize Neuralink’s BCI system extensively, logging around eight hours daily during the week and up to 10 hours on weekends.
