Noland Arbaugh was paralysed from the shoulders down after a diving accident eight years ago. But now, thanks to a brain computer interface chip, he's able to play video games like Mario Kart or virtual chess simply by concentrating his mind on the screen.

The chip, which is the size of a coin, was surgically implanted back in January by Elon Musk's company, Neuralink. While the company have said there are still a few problems to work through, it is incredible technology that promises to give people with severe disabilities a much better quality of life.

So how does this technology work, and is it as incredible as it appears? 

On this episode of The Briefing, Bension Siebert is joined by neural engineering expert, Associate Professor Sam John to explain how this works, the ethical dilemmas and how common it could be in the future.
