Elon Musk announces third patient receives Neuralink brain implant

Elon Musk announced that a third person has received a Neuralink brain implant, with all three patients reportedly doing well. The company has improved its devices, adding more electrodes and enhancing battery life since the first implant a year ago. Musk aims to implant devices in 20 to 30 more people this year. The second patient, who has a spinal cord injury, is already using the device to play video games and learn design software. The first patient has also shared positive experiences with gaming. Neuralink is one of many groups developing brain-computer interfaces (BCIs). Over 45 trials are currently underway, with other companies using less invasive methods. The FDA oversees the testing and regulation of these high-risk devices to ensure safety.
