Neuralink enrols its second test patient just two months after the first brain chip recipient suffered potentially life-threatening complications - and Elon Musk claims trial numbers could be in 'high single digits this year'

Neuralink is ploughing ahead with plans to place another implant in a human brain, despite complications for the first recipient. Founder Elon Musk has said that his neurotechnology firm is'moving on' to a second procedure in another patient – although he didn't reveal who it will be. He also wants to ramp up the number of operations to'high single digits' by end of year. Neuralink's chip interprets neural activity in the brain so a person can operate a smartphone or control a computer cursor just by thinking. But the first recipient suffered a potentially life-threatening condition during surgery that later caused his brain chip to malfunction, a report claimed.
