Neuralink, the brain chip implant developed by Elon Musk, has been making waves in the medical and technological fields. Recently, Brad Smith, the third person in the world to receive the Neuralink implant and the first person with ALS to do so, showcased how he uses the technology in his daily life.
ALS, also known as Lou Gehrig’s disease, is a progressive neurodegenerative disorder that affects motor neurons, leading to a loss of voluntary muscle movement over time. This condition can impact a person’s ability to speak, eat, move, and breathe independently.
In a YouTube video posted by Smith, he demonstrated how the brain-computer interface (BCI) of the Neuralink implant allows him to control the mouse on his MacBook Pro using signals from his brain. This innovative technology, placed in his motor cortex, is about the size of five stacked quarters and contains over 1,000 electrodes. Smith explained that the implant interprets his brain signals to determine how and where he wants to move the cursor, enabling him to edit videos and perform tasks with precision.
Initially, Smith attempted to control the cursor by imagining moving his hand, but he found it more effective to think about moving his tongue and clenching his jaw to manipulate the cursor and click the mouse virtually. Additionally, artificial intelligence was used to create a synthetic version of Smith’s voice based on recordings from before he lost the ability to speak, allowing him to narrate the video in his own voice.
During a visit from Neuralink’s team, Elon Musk phoned Smith and expressed his hope that the technology would be a game-changer for Smith and his family. Smith, who had been using eye-gaze technology for communication, shared that the Neuralink implant has expanded his ability to communicate outdoors and in varying lighting conditions, offering him newfound independence and freedom.
Moreover, the Neuralink implant has allowed Smith to engage in activities like playing video games with his kids, showcasing the positive impact of this groundbreaking technology on his quality of life. Smith expressed his excitement about serving others in the future with this technology, highlighting the profound impact it has had on his life.
Neuralink, which was first tested on monkeys before being implanted in humans, has shown promising results in improving the lives of individuals with neurological conditions. Noland Arbaugh, the first human patient to receive the Neuralink implant, shared how it has helped him regain independence and make new social connections.
The advancements in Neuralink technology hold great potential for enhancing the quality of life for individuals with neurological disorders, offering hope for a future where technology can empower individuals to overcome physical limitations. The incredible journey of Brad Smith and others like him demonstrates the transformative power of innovation in the field of neurotechnology.
