Elon Musk’s Neuralink cleared for human test of brain implants

Elon Musk’s start-up Neuralink on Thursday said it has approval from US regulators to test its brain implants in people.

Elon Musk’s start-up Neuralink on Thursday said it has approval from US regulators to test its brain implants in people.

Neuralink said clearance from the US Food and Drug Administration (FDA) for its first in-human clinical study was “an important first step” for its technology, which is intended to let brains interface directly with computers.

“We are excited to share that we have received the FDA’s approval to launch our first-in-human clinical study,” Neuralink said in a post on Musk-run Twitter.

Recruitment for a clinical trial is not yet open, according to Neuralink. The aim of Neuralink implants is to enable human brains to communicate directly with computers, Mr Musk said during a presentation by the start-up in December.

“We’ve been working hard to be ready for our first human (implant), and obviously we want to be extremely careful and certain that it will work well before putting a device in a human,” he said at the time.

Neuralink prototypes, which are the size of a coin, have been implanted in the skulls of monkeys, demonstrations by the start-up showed.

In February 2022, the company was sideswiped by a legal battle over its alleged mistreatment of test subjects.

The Physicians Committee for Responsible Medicine (PCRM) has come after the company for causing “extreme suffering” for its test subjects. A statement put to the US Department of Agriculture (USDA) claimed monkeys “had their brains mutilated in shoddy experiments and were left to suffer and die”.

At a presentation, Neuralink showed several monkeys “playing” basic video games or moving a cursor on a screen through their Neuralink implant.

The technology has also been tested in pigs.

With the help of a surgical robot, a piece of the skull is replaced with a Neuralink disk, and its wispy wires are strategically inserted into the brain, an early demonstration showed.

The disk registers nerve activity, relaying the information via common Bluetooth wireless signal to a device such as a smartphone, according to Mr Musk.

“It actually fits quite nicely in your skull,” Mr Musk said during a prior presentation.

“It could be under your hair and you wouldn’t know.”

Mr Musk said the company would try to use the implants to restore vision and mobility in humans who had lost such abilities.

“We would initially enable someone who has almost no ability to operate their muscles … and enable them to operate their phone faster than someone who has working hands,” he said.

“As miraculous as it may sound, we are confident that it is possible to restore full body functionality to someone who has a severed spinal cord,” he said.

Beyond the potential to treat neurological diseases, Mr Musk’s ultimate goal is to ensure that humans are not intellectually overwhelmed by artificial intelligence (AI), he said.

Other companies working on similar systems include Synchron, which announced in July that it had implanted the first human brain-machine interface in the United States.

The aim of Neuralink implants is to enable human brains to communicate directly with computers, Musk said during a presentation by the start-up in December.

Members of the Neuralink team have shared a “wish list” that ranged from technology returning mobility to the paralysed and sight to the blind, to enabling telepathy and the uploading of memories for later reference — or perhaps to be downloaded into replacement bodies.

Meanwhile, Mr Musk recently established a business devoted to developing sophisticated AI. The boss of Tesla has also predicted that autonomous driving technology at the electric car maker is heading for a breakthrough.

Mr Musk has contended that synching minds with machines is vital if people are going to avoid being so outpaced by AI that, under the best of circumstances, humans would be akin to “house cats.” Experts and academics remain cautious about his vision of symbiotically merging minds with super-powered computing.
