Tesla CEO Elon Musk's neurotechnology company Neuralink plans to begin human clinical trials of its wireless brain computer chips in an estimated six months.

"We're extremely cautious and want to make sure that it works well before we put a device in a human, but we've filed, I believe, most of our paperwork with the FDA," Musk said during a presentation of the implant on Wednesday.

Musk wants to use the interfaces to heal neurological diseases such as Alzheimer's, dementia and spinal cord injuries.

Based in Austin, Texas, the company has successfully conducted clinical trials on animals over the past several years.

In Neuralink's last public presentation more than a year ago, a monkey with a brain chip controlled a computer game with its mind alone.

However, Neuralink is behind its announced schedule.

Musk predicted in 2019 that he would seek regulatory approval by the end of 2020.

At a conference in late 2021, he said he hoped to start human trials later this year.
