Elon Musk expects Neuralink’s wireless brain chip to begin human clinical trials in six months.
Musk’s Neuralink is developing brain chip interfaces that could enable disabled patients to move and communicate again.
The brain chips are also being made to restore vision, Musk added on Wednesday.
Neuralink has in recent years been conducting tests on animals as it seeks approval from the U.S. Food and Drug Administration (FDA) to begin clinical trials in people.
Musk told a crowd of select invitees in a presentation at Neuralink headquarters that though "progress should be exponential", progress " as it applies to humans, will seem perhaps agonizingly slow".
The first two human applications targeted by the Neuralink device will be in restoring vision and enabling movement of muscles in people who cannot do so, Musk said.
Neuralink’s last public presentation, more than a year ago, involved a monkey with a brain chip that played a computer game by thinking alone.
Musk wants to develop a chip that would allow the brain to control complex electronic devices and eventually allow people with paralysis to regain motor function and treat brain diseases such as Parkinson’s, dementia, and Alzheimer’s. He also talks of melding the brain with artificial intelligence.
