In a stunning medical breakthrough, Bradford G. Smith, an ALS patient who lost his ability to speak, has regained communication thanks to Neuralink’s brain implant. Smith is the third person globally to receive the implant and the first non-verbal ALS (Amyotrophic Lateral Sclerosis) patient who can now express himself through AI-driven brain-computer interface (BCI) technology.
Before receiving the implant, Smith was completely paralyzed and relied on a ventilator, using an eye-gaze control system to communicate—an inefficient and time-consuming method. With the Neuralink brain implant, he can now control a computer cursor using his brain signals, allowing faster and more flexible interaction.
Smith reported via X that the implant is in his motor cortex. He also made and posted a video on YouTube using the brain-computer interface to control the mouse on his MacBook Pro.
Through this video, he explained how Neuralink impacted his life and offered an overview of how it works.
The implant contains 1,024 tiny electrodes that capture and translate neural activity into commands.
AI processes these signals in real-time, enabling Smith to type and navigate digital interfaces solely through thought. His original voice was also cloned using AI, enabling him to speak through a synthesized version of his past voice.
Wireless Brain Implant Has Enabled Paralyzed Primates To Walk Again
The implant involves replacing a small section of the skull with a chip, with threads delicately inserted a few millimeters into the brain. These threads are designed to avoid blood vessels, making the procedure minimally invasive.
Initially, Smith attempted to control the cursor using imagined hand movements, but after trial and error, he now successfully navigates using tongue movements and selects options by clenching his jaw.
Neuralink developed a chat application that listens to conversations and suggests real-time responses using Smith’s AI-generated voice to enhance communication speed further.
The system is powered by Grok 3 AI and streamlines interactions, helping him actively engage with others despite his physical limitations.
Smith’s case offers new hope for individuals with severe motor disabilities, showcasing the potential of brain-computer interfaces in neurological treatment. Neuralink’s technology could significantly improve the lives of patients suffering from conditions like ALS, spinal cord injuries, and locked-in syndrome.
Despite the challenges of ALS, Smith remains optimistic, sharing, “Even though having ALS sucks, I am happy, and God has answered my prayers—life is good.”
This groundbreaking advancement marks a new chapter in neurotechnology, proving that AI-powered implants may soon revolutionize communication, mobility, and independence for millions worldwide.
