Neurologist explains how Neuralink's brain chip actually works

The first clinical trials for the Neuralink brain implant are about to take place.

The chip will allow people to control smartphones and computers using their thoughts alone.

While this certainly sounds cool, what does the medical world think?

Dr Leah Croll, a neurologist, gave her insights on what Elon Musk’s brain chip will mean for the world.

Neuralink is preparing to implant its first round of brain chips.

Elon Musk has stated that the chips will provide a way for paralyzed people to control phones and computers with their brains.

If successful, this will revolutionize the medical field.

While some worry that this technology is the stuff of dystopian nightmares, a doctor recently weighed in on the topic.

Dr Leah Croll told ABC News that the medical world is generally feeling positive about Neuralink’s project.

“My reaction is one of hope and excitement, as we’re talking about having a medical miracle potentially within our grasp in the next few years,” she said.

She also explained exactly how a chip like this would work.

The device has been designed to work like a specialized sensor, able to read the electrical signals that our brain sends out.

It then translates those signals into action, in the case of Neuralink, to control a smartphone or a computer.

Dr Croll shared the potential risks and dangers of a device like this too.

Firstly, brain surgery is always risky no matter what the procedure is, so the implantation process poses an early danger.

Next, she says there is the worry that the implant could put the patient in jeopardy.

This could involve the signals being misinterpreted and the wrong actions being performed.

Or, worse, the signals being intercepted by hackers.

Dr Croll would need more information before stating whether the benefits outweigh the potential risks.

If successful, however, she says that devices like this would have incredible implications.

“The idea that we would be able to give neurological function back is so groundbreaking and so meaningful,” she says.

“It’s hard to imagine anything more beneficial for those patients.”

Neuralink is focusing on people who have lost mobility while some other companies are working with people who have lost language capabilities.

The trial will still take a few years but Dr Croll feels certain we will see Neuralink’s device working in her lifetime.
