Elon Musk announces third patient receives Neuralink brain implant

Elon Musk announced that a third patient has received a Neuralink brain implant, part of ongoing efforts to connect the nervous system to machines. The company has upgraded its devices, aiming to implant 20 to 30 more this year. The second patient, who has a spinal cord injury, is using the device to play video games and learn design software. The first patient has also reported benefits, including playing games and chess. Neuralink's approach involves robotic surgery to implant flexible electrodes, potentially recording from more neurons than other methods. However, other companies are advancing in brain-computer interface technology with less invasive techniques.
