According to the corporate, an issue occurred with Neuralink's first human brain implant

Elon Musk's startup Neuralink announced Wednesday that a part of its brain implant malfunctioned after it used the system on a human patient for the primary time.

Neuralink has developed a brain-computer interface (BCI) that might ultimately help patients with paralysis control external technology using just their minds. The company's system, called Link, records neural signals using 1,024 electrodes across 64 “threads” that it says are thinner than a human hair website.

In January, Neuralink implanted the device in a 29-year-old patient named Noland Arbaugh as a part of a study to check its safety. The company streamed a live video with Arbaugh as he used the BCI in March, and Neuralink said in a single April blog post that the operation went “extremely well”.

But within the weeks since, various threads have withdrawn from Arbaugh's brain, Neuralink said in an announcement blog entry Wednesday. This meant there have been fewer effective electrodes, affecting the corporate's ability to measure the speed and accuracy of the link.

Neuralink didn’t disclose what number of sutures were withdrawn from the tissue. The company didn’t immediately reply to CNBC's request for comment.

To get around this problem, Neuralink said it modified the recording algorithm, improved the user interface and worked to enhance techniques for translating signals into cursor movements, the blog post said. Neuralink reportedly considered removing the implant, but the issue didn’t pose a direct risk to Arbaugh's safety, it said The Wall Street Journal, who previously reported the issue. According to the report, Neuralink shared its blog post after the Journal asked the corporate concerning the issue.

Although some stitches were withdrawn from Arbaugh's brain tissue, Neuralink said he uses the corporate's BCI system for about eight hours a day in the course of the week and infrequently as much as 10 hours a day on weekends.

Arbaugh said the link was like a “luxury overload” and that it helped him “reconnect with the world,” the blog post said.

Neuralink shouldn’t be the one company developing a BCI system, and the technology has been researched in academic settings for a long time.

Neuralink still has an extended road of safety and effectiveness testing before it could possibly be approved by the U.S. Food and Drug Administration to commercialize the technology.
