Neuralink, the brain-machine interface startup founded by Elon Musk, has successfully implanted its device in a second patient, marking a significant milestone in the company’s quest to revolutionize digital interaction for individuals with spinal cord injuries. The device, designed to enable paralyzed patients to control digital devices through thought alone, has shown promising results in both its first and second recipients.
In a recent podcast interview with Lex Fridman, Musk shared details about the progress of Neuralink’s technology. He revealed that the second patient, who has a spinal cord injury similar to the first patient, is experiencing impressive results. According to Musk, all 400 of the 1,024 electrodes in the implant are functioning well, providing substantial brain signal data.
Musk expressed cautious optimism about the second implant, noting that it “seems to have gone extremely well.” He emphasized that the device has generated a strong signal, suggesting successful integration and functionality. While specific details about the timing of the second surgery were not disclosed, Musk indicated that Neuralink plans to implant its device in eight additional patients within the year as part of its clinical trials.
The first patient, Noland Arbaugh, shared his experiences during the podcast, highlighting the transformative impact of the implant on his daily life. Before receiving the Neuralink device, Arbaugh relied on a mouth stick to interact with a tablet. Now, he can control his computer simply by thinking, allowing him to perform tasks like playing video games, browsing the internet, and posting on social media with greater independence.
Arbaugh faced initial challenges when the tiny wires of his implant retracted, reducing the number of functioning electrodes. However, Neuralink addressed this issue by refining its algorithms and making other adjustments to restore the implant’s performance. Despite the initial setbacks, Arbaugh has managed to surpass his previous record for controlling a cursor with thought alone.
In addition to discussing Neuralink’s advancements, Musk touched on other topics during the podcast, including his discussions with Republican presidential candidate Donald Trump about forming a commission to improve government efficiency and reduce business regulations.
As Neuralink continues to push the boundaries of brain-machine interfaces, the success of its second implant brings hope for greater autonomy and enhanced quality of life for individuals with severe spinal cord injuries.
