Elon Musk’s Neuralink Hits 21 Patients as Brain Implant Trials Scale Up
Elon Musk’s brain-computer interface company, Neuralink, says it has expanded its human clinical trials to 21 participants worldwide, marking two years since it began testing its brain implant technology on humans.
The company said the increase reflects growing confidence in the safety and performance of the implant, which allows users with spinal cord injuries to control digital tools using their thoughts. Earlier participants have demonstrated the ability to play video games, browse the internet and operate computer cursors hands-free.
Neuralink began human trials in 2024 after addressing safety concerns that initially delayed regulatory approval. According to the company, no serious device-related adverse events have been recorded so far.
The firm said expanding trials will help researchers better understand differences in how patients respond to the implant, while refining both the hardware and surgical procedures.
