Neuralink Advances: Brain Chip Successfully Implanted in Second Human Patient
Elon Musk revealed during a recent appearance on Lex Fridman’s podcast that Neuralink has successfully implanted its brain chip in a second individual as part of its inaugural human trial phase. The specifics regarding the date of the procedure or the identity of the patient remain confidential, as reported by Reuters.
Promising Early Results
Musk shared that out of 1,024 electrodes implanted in the patient’s brain, 400 are functioning effectively. “I hesitate to say too much, but everything appears to be progressing remarkably well,” he noted. “There’s substantial activity from numerous electrodes; it’s operating very efficiently.”
The Potential of Neuralink’s Technology
This groundbreaking device enables individuals with spinal cord injuries to engage with video games, navigate online platforms, and control various electronic devices solely through their thoughts. Following FDA clearance earlier this year, Neuralink issued a call for applications for participants in its second round of clinical trials.
Experiences from Initial Trial Participant
Nolan Arbaugh was the first individual to receive a Neuralink implant and described his experience as “extremely straightforward.” During an impressive demonstration provided by the company, Arbaugh showcased his ability to manipulate a cursor on a laptop screen, pause music applications seamlessly, and even play chess and Civilization VI.
A Shift Towards Independence
During an engaging discussion with Musk and Fridman on their podcast marathon, Arbaugh expressed how this innovative technology empowers him to perform tasks on-screen simply by envisioning them. This capability significantly lessens his dependency on assistance from caregivers.
Tackling Challenges Post-Surgery
Nonetheless, complications arose soon after Arbaugh’s procedure when several electrodes withdrew from their intended positions within his brain. To address this issue retrospectively, Neuralink adapted its algorithm for improved sensitivity in subsequent tests. In response to these challenges identified during Arbaugh’s surgery, they informed the FDA about plans for future operations that will anchor implant threads deeper into patients’ brains—aiming to mitigate movement.
Pioneering Research Beyond Humans
Prior experiments have seen Neuralink test its implants on animals—including primates—which have drawn scrutiny leading to federal investigations regarding those practices.
A Promising Future Ahead?
Despite past hurdles associated with animal testing practices and initial human trials feedbacks prompting adjustments in technique overall patient interest remains high; over 1,000 volunteers are reportedly eager to participate in Phase Two surgical trials according to Musk’s statements. He anticipates that up until late 2024 another eight patients could also receive chips through this pivotal research initiative.
