Elon Musk's Neuralink has successfully implanted brain-computer interfaces in three humans, with plans for more this year. The devices have shown promise in helping paralyzed patients regain abilities like playing video games. Other companies are also developing similar technologies, with various trials underway.

The technology holds potential benefits for people with paralysis, but its safety and feasibility remain uncertain. Regulatory processes for testing BCIs involve oversight from the FDA and ethical review boards. Teljes cikk (Euronews.com)
