Sources told The Wall Street Journal that the company considered having the chip removed from its test subject.
’s neurotech startup Neuralink said Wednesday it has run into problems with a brain chip it implanted into a 29-year-old quadriplegic man earlier this year, with the issues considered so serious, it reportedly considered having the implant removed entirely.
Neuralink said those failures were caused by some of the implant’s 64 threads retracting and becoming unusable. It didn’t specify how many of the threads—the microscopic links that transport his brain signals to a chip that allows him to control technology with his mind—were impacted, nor did it say what caused the error.
Neuralink says its goal is to return a relative sense of normalcy to those with full-body paralysis, like Arbaugh. In media releases, Neuralink showed previously that Arbaugh had regained the ability to do some tasks thanks to the chip—like playing video games using only his mind.
