Neuralink enables paralyzed patients to control devices with brain chip

Neuralink, the brain-computer interface startup founded by Elon Musk, has successfully implanted its device in a second patient, aiming to enable paralyzed individuals to control digital devices through thought alone. Musk announced this development during a lengthy podcast, revealing that the second participant, who has a spinal cord injury similar to the first patient, has 400 functioning electrodes implanted in their brain. He expressed optimism about the procedure, stating, “It seems to have gone extremely well with the second implant.” The first patient, Noland Arbaugh, shared his experience on the podcast, highlighting the significant change in his ability to interact with technology since receiving the implant in January. Previously reliant on a stick to tap a tablet screen, Arbaugh can now control the device simply by thinking about his desired actions. He noted that the implant has granted him greater independence and reduced his need for caregiver assistance. Despite initial challenges with the implant's performance, Neuralink successfully restored its functionality by enhancing the sensitivity of its monitoring algorithms. Arbaugh has even surpassed his previous record for cursor control using only his thoughts, achieving this with a limited number of active electrodes. Musk indicated that Neuralink plans to expand its clinical trials, aiming to provide implants to eight additional patients this year. In addition to discussing Neuralink's advancements, Musk mentioned his conversations with Republican presidential candidate Donald Trump about forming a commission to enhance government efficiency through reduced business regulations.
