Neuralink’s brain implant has enabled the first ALS patient to communicate with his mind, representing a breakthrough for individuals with severe motor impairments. Bradford Smith, the third person to receive the implant and the first nonverbal recipient, demonstrated the ability to “type with his brain” despite being largely immobile and requiring ventilator assistance. This advancement signals a potential transformation in how technology can restore basic communication capabilities for those with debilitating neurological conditions.

The breakthrough technology: Neuralink’s device, approximately the size of five stacked U.S. quarters, connects to the brain’s motor cortex through flexible threads that detect neural activity.

  • The implant transmits signals wirelessly to external computing systems where machine learning algorithms interpret them into actionable commands.
  • Smith uses an AI-cloned version of his voice to communicate, demonstrating how the technology enables expression for someone who can move only his eyes.

What it means for patients: The Neuralink implant has significantly improved Smith’s quality of life despite the severe limitations imposed by ALS.

  • “Neuralink has given me freedom, hope and faster communication,” Smith explained in his video statement on X.
  • According to Neuralink, the device has already enabled Smith to watch his son win a robotics competition, chat with neighbors, and give a presentation at his local church.

The scientific approach: Neuralink is developing a comprehensive communication system specifically designed for patients with severe motor impairments.

  • The company is combining language models with novel neural decoding strategies to allow more natural speaking pace.
  • This work represents the practical application of brain-computer interface technology that began human trials in January 2024 after receiving FDA clearance in May 2023.

Looking ahead: Neuralink’s clinical trials are expanding beyond their initial boundaries to reach more potential patients.

  • The company currently has active trials in both the United States and Canada.
  • Neuralink is also connecting with people in the United Kingdom who might participate in future clinical investigations.
