The first patient with Elon Musk’s company’s brain implant Neuralink explained how his life changed after placementdespite any technical problems that fatally arise.

Nolan Arbo, 29, said he uses the chip almost every day. This allows him to post on social media, respond to emails, play video games, read comics, learn Japanese, etc., abilities that seemed impossible after his accident.

The young man stayed in June 2016 paralyzed from the neck down, after a swim in shallow water. Being a very active person, he found it difficult to adapt to the new conditions of his life.

Arbo’s chip connects to the computer via Bluetooth, and there’s still plenty of room for improvement. The battery of the device only lasts a few hours, after which he must lie down on a special pillow and recharge it. In the future, the battery capacity will increase.

The chip is designed to record neural activity via 1,024 electrodes distributed across 64 flexible leads, or “threads,” each of which is finer than human hair and can be placed independently in the brain, according to Neuralink’s website.
