Elon Musk’s brain implant company is looking for three more human test subjects for its extensive study. 

According to the company’s posting on a clinical trials database, Neuralink is looking for patients with limited or no mobility in their wrists, hands or arms due to a spinal injury or neurological disorder. Potential patients also must be between the ages of 22 and 75 and have a life expectancy longer than one year. 

The company hopes to find 10 total human subjects for its brain-computer interface technology for its study. The full study is expected to be completed by 2031. 

Neuralink began human trials in January when it implanted its device into Noland Arbaugh, a quadriplegic. The device has enabled him to control a computer with just his mind. The company shared a live stream in April that showed Mr. Arbaugh remotely playing a game of chess using the implant. 

Despite the proposed expansion of its study, Neuralink has come under fire for issues with its testing procedures and its technology. Earlier this month, Neuralink reported that some of the fibers that were inserted into Mr. Arbaugh’s brain retracted, resulting in a reduction in performance. 

Even before the most recent malfunction, Neuralink had been accused of cutting corners during its preliminary testing. Some former employees have accused the company of using inhumane tactics on its animal test subjects, saying that Neuralink has been responsible for numerous unnecessary deaths.
