‘I Have a Lot to Say’: Brain Implant Helps a Disabled Patient Speak

Key Points:

• Paradromics announced that a 68-year-old woman with primary lateral sclerosis used their wireless brain-computer interface (BCI) implant to have real-time conversations, including speaking via a computer-generated voice by imagining speech without moving her muscles.
• The Connexus BCI system, implanted with over 400 electrodes, decodes brain signals related to speech attempts, imagined speech, and listening, enabling spontaneous communication without tethering the patient to a computer.
• This clinical trial, approved by the FDA, will include 10 patients with speech and limb paralysis from various neurological disorders, aiming to improve communication capabilities and daily life integration.
• Experts highlight the significance of Paradromics' wireless and self-contained system compared to previous wired BCIs, noting it as a major step toward practical clinical use for restoring speech in severely paralyzed individuals.
• Parallel research at UCSF demonstrated decoding of both speech and physical gestures from brain signals, indicating progress toward BCIs that can control multiple body functions simultaneously, enhancing communication and interaction.
