Life before Neuralink
Before the advent of the Neuralink implant, Brad G. Smith faced significant barriers in communication due to the progression of his ALS. This condition severely affects the nerves controlling voluntary muscle movements, leading to a gradual loss of his ability to speak and move. For years, he relied on eye-tracking technology that, despite its innovation, presented numerous challenges.
“It is a miracle of technology, but it is frustrating. It works best in dark rooms, so I was basically Batman. I was stuck in a dark room,”
Smith explained in a recent post on social media.
The eye-tracking device functioned well under dim lighting but faltered in brighter environments, leading to slow and often frustrating communication attempts. The limitations of the technology not only hindered his interactions with loved ones but also affected his emotional well-being. After receiving the Neuralink implant, however, Smith expressed newfound joy in being able to communicate freely, stating,
“Neuralink lets me go outside and ignore lighting changes.”
How the Neuralink brain implant works
The Neuralink device that Smith received is a sophisticated Brain-Computer Interface (BCI), making him the first non-verbal person and only the third person worldwide to utilize this technology. The implant, about the thickness of five stacked coins, resides in his skull and connects to the motor cortex—the area responsible for movement. It contains tiny wires, smaller than human hair, that penetrate into Smith’s brain.
These microscopic wires capture neural signals and transmit them wirelessly to a connected device, decoding Smith’s thoughts into actions on a computer. The implant has 1,024 electrodes that capture neuron firings every 15 milliseconds, producing a wealth of information for the system to analyze. Smith described how the implant operates, stating,
“Neuralink does not read my deepest thoughts or words I think about. It just reads how I wanna move and moves the cursor where I want.”
This rapid decoding of brain signals allows Smith to move a cursor across a screen using only his thoughts, dramatically enhancing his ability to communicate and interact online. The technology has immense potential, particularly for individuals with similar conditions affecting their ability to communicate.
Training the brain-computer connection
Adjusting to the Neuralink implant required a period of trial and error. Initially, attempts to map Smith’s hand movements to cursor movements were not effective. However, further research indicated that the signals associated with tongue movements proved to be more reliable for navigating the cursor. Additionally, clenching his jaw became the mechanism for executing clicks on the screen.
Smith elaborated on how this technique evolved, saying,
“I am not actively thinking about my tongue, just like you don’t think about your wrist when you move a mouse. I think my brain has switched over to subconscious control quickly.”
By enabling this connection, Smith has begun to use the technology more naturally, transitioning cursor movement into a subconscious task.
Everyday life: Communication, play, and problem-solving
The benefits of the Neuralink implant extend far beyond mere communication; it has provided Smith with the ability to engage in daily activities that many take for granted. He can now interact with his family through video games like Mario Kart, bringing a sense of normalcy to family life. The system includes a virtual keyboard, along with shortcuts for tasks like copying and pasting, significantly streamlining his online navigation.
Smith collaborated with Neuralink engineers to create features that cater to his unique needs. One such feature he developed is a “parking spot” for the cursor, allowing him to set it aside while he watches videos or takes breaks. He noted,
“When it is in the parking spot, I can watch a show or take a nap without worrying about the cursor.”
The human side: Family, faith, and perspective
While technological advancement has transformed Smith’s ability to communicate, his journey has also been profoundly influenced by personal factors. Smith attributes his resilience to the unwavering support of his wife, Tiffany, calling her the “best caregiver I could ever imagine.” He acknowledges the role of family, friends, and faith in navigating the daily challenges presented by ALS.
Despite the hardships associated with the disease, Smith finds solace in his faith, expressing that he has gained a deeper understanding of his journey. He mentioned,
“I have not always understood why God afflicted me with ALS but with time I am learning to trust his plan for me.”
Smith believes that these experiences have not only strengthened his character but also brought him closer to his family and his faith.
