Brain implants with AI enable unprecedented communication for paralyzed individuals
Two groundbreaking studies published in the journal Nature have showcased the potential of brain implants equipped with artificial intelligence (AI) to revolutionize communication for paralyzed individuals. The studies highlight the progress in brain-computer interface (BCI) technology.

Despite their speech impairments, they were able to mentally formulate words.

The implanted devices, utilizing AI algorithms, decoded their intended speech at rates of 62 and 78 words per minute, respectively. These rates significantly surpass previous records and approach the tempo of normal conversation.

BCIs collect and analyze brain signals, translating them into commands for external devices. In the past, BCIs have enabled paralyzed individuals to control robotic arms, play video games, and send emails using their thoughts.

In one of the studies conducted by Stanford University, researchers utilized the Utah array—a sensor with 64 needle-like electrodes—to collect neural activity associated with facial movements involved in speech. They trained an artificial neural network to decode this activity and translate it into words displayed on a screen. The participant, who had ALS, achieved a communication rate of 62 words per minute with a vocabulary of 125,000 words and a 23.8% error rate.
University of California, San Francisco (UCSF) study: Capturing lip movements for communication
The second study, conducted by the University of California, San Francisco (UCSF), employed an array with 253 electrodes placed on the brain's surface to capture neural data related to lip movements. They trained a deep-learning model to decipher this data, enabling the participant, who had experienced a stroke, to communicate at a rate of 78 words per minute. The error rate for a 50-phrase vocabulary was 4.9%, with simulations estimating a 28% word error rate for a vocabulary of over 39,000 words.
While both approaches had trade-offs—implanted electrodes providing detailed information but being less stable, and surface arrays offering stability but recording less detailed brain activity—the achievements of these studies signify significant progress in BCI technology. They offer hope for paralyzed individuals to regain the ability to communicate effectively and intuitively, with researchers emphasizing the potential for further advancements as technology continues to evolve in this field.
