Just Happened! NEURALINK Second Human Trials! Elon Musk Reveals NEW Updates
Elon Musk’s Neuralink has made headlines again with the announcement of their second human trial. After some complications with the first patient, the company has successfully implanted the chip into a second patient, this time with notable improvements and modifications. But how safe is this new generation of the Neuralink implant? What are the long-term risks, and what does this mean for the future of neurotechnology? Let's dive into the details of Neuralink's second human trial and the latest updates from Elon Musk himself.
Neuralink's Second Patient: A New Beginning
Following the initial trials with Nolan Arbaugh, who received the first Neuralink implant, the company has moved forward with a second patient. This patient, like Arbaugh, suffered a spinal cord injury that left him paralyzed. However, this second trial has seen some unexpected successes, thanks to several key changes in the implant device.
Elon Musk recently shared the results of this new implant in a detailed 8-hour video. The second patient’s condition is remarkably similar to that of Nolan Arbaugh, providing Neuralink with another opportunity to test and refine their technology. While Musk has been cautious about revealing the patient's identity, he did hint at the success of the procedure, stating, "I don't want to jinx it, but it seems to have gone extremely well with the second implant."
What’s New with the Second Generation Neuralink Implant?
One of the significant changes in the second generation of Neuralink's implant is the redesign of the device itself. The original chip had 64 threads, each thinner than a human hair, with 16 electrodes per thread, totaling 1,024 electrodes. The new chip, however, has been upgraded to include 128 threads, each with eight electrodes, potentially doubling the bandwidth if the thread positions are accurately identified.
Additionally, the threads for this second patient have been implanted at a deeper level compared to the first patient. Instead of the previous depth of 3-5mm, the electrodes have been implanted 8mm deep from the brain surface. This deeper implantation is designed to secure the threads more firmly, addressing issues like the retraction of threads that led to an 85% signal loss in the first patient.
Challenges and Solutions: The Road to Improvement
The Neuralink team also identified that residual air pockets in the brain, introduced during surgery, contributed to the threads retracting. To combat this, Neuralink’s head neurosurgeon, Matthew McDougall, explained that the team has implemented measures to maintain the patient’s carbon dioxide levels within a normal range during surgery, preventing the brain from expanding or retracting.
Furthermore, the implant device has been better sculpted to eliminate gaps under the skull, ensuring closer contact with the brain and reducing tension on the threads.
Results of the Second Implantation: Promising, but Not Perfect
While the second-generation chip has shown promising improvements, it has not yet reached its full potential. According to Musk, only 400 out of 1,024 electrodes are currently active, meaning the chip is operating at about 40% capacity. This is still a significant improvement, and the results are encouraging, but there is room for further optimization.
Despite these limitations, the success of the second patient’s implantation is a significant step forward. Musk revealed that even with a lower percentage of functioning electrodes, the patient has already shown remarkable progress, similar to Nolan Arbaugh’s achievements.
Neuralink's Vision for the Future: Enhancing Human Abilities
Elon Musk has long promoted Neuralink as a means to enhance human capabilities, particularly in the face of advancing AI technology. He envisions a future where Neuralink could help humans integrate with AI, allowing us to compete with and potentially surpass artificial intelligence systems.
In addition to treating paralysis, Musk has hinted at the possibility of using Neuralink to restore vision to the blind, enhance cognitive abilities, and even repair damaged neurons. While these ambitions are still in the early stages, the progress made with the second patient indicates that Neuralink is on the right track.
Neuralink’s Upcoming Plans: Expanding the Trials
With over 1,000 volunteers ready to participate in upcoming trials, Neuralink is set to accelerate its efforts. Musk aims to have eight more patients implanted with the chip by the end of the year, pending regulatory approval. The company is also working on a new product called “Blindsight,” designed to restore vision to blind patients by stimulating the visual cortex.
While restoring vision presents more challenges than treating paralysis, Neuralink’s ongoing research and development efforts suggest that these goals are within reach.
The Procedure: A Closer Look
The implantation process for the second patient has remained largely unchanged, aside from the increased depth and number of threads. According to McDougall, the procedure involves making a small incision in the scalp, removing a portion of the skull, and using a robot to precisely insert the threads into the brain.
This robotic precision is crucial for avoiding blood vessels and ensuring the electrodes are placed at the optimal depth. Once the threads are in place, the implant is secured to the skull, and the skin is stitched back together.
Overcoming Controversies and Challenges
Neuralink has not been without its controversies. The company has faced criticism from animal rights groups and former employees, particularly regarding the treatment of animals used in their research. Despite these challenges, Musk remains focused on the potential benefits of Neuralink’s technology, both for medical treatment and enhancing human abilities.
Conclusion: A Step Toward the Future of Neurotechnology
Neuralink’s second successful chip implantation marks a significant milestone in the field of neurotechnology. By addressing the challenges encountered during the first trial and demonstrating promising early results, Neuralink is paving the way for future breakthroughs that could transform the treatment of neurological conditions.
As the company continues to refine its technology and expand its trials, the potential for Neuralink to enhance human abilities and facilitate a symbiosis between humans and AI becomes increasingly tangible. The road ahead is long, but the progress made so far is a testament to the transformative potential of brain-computer interfaces.
