BCI expands to restore speech, feeding and touch

Overview

Researchers at the University of California, Davis have demonstrated that an implanted intracortical brain‑computer interface (BCI) can restore spoken communication for a man with advanced amyotrophic lateral sclerosis (ALS). The system, using four micro‑electrode arrays in the motor cortex, decodes neural activity into text and synthetic speech, enabling about 56 words per minute with 99 % word‑level accuracy. Over roughly two years of home use, the participant logged more than 3,800 hours, generated 183,060 sentences (≈1.96 million words) and controlled a cursor for email, web browsing and remote work. The team is working toward a fully wireless version. In July 2026, neurologists in New York reported a “double neural bypass” that links five brain microelectrodes to forearm muscles of a tetraplegic patient, restoring functional hand movements and a sense of touch. A 3‑D‑printed splint‑based sensor array stimulates the sensory cortex, enabling the patient to pick up fragile objects with roughly 90 % success. A further advance was reported in July 2026 by the Feinstein Institutes. Their neural bypass combines a BCI with peripheral nerve stimulation, translating arm‑movement intent into electrical impulses that activate muscles while pressure sensors convey tactile feedback to the brain. After 35 weeks of training, the tetraplegic participant’s arm strength improved substantially, allowing independent feeding and object manipulation with partial texture sensation. Later that month, the same team detailed a long‑term study of a double neural bypass implanted in Keith Thomas, a New Yorker paralyzed from the chest down after a diving accident. AI‑driven software decoded movement intent and routed signals around a complete spinal cord injury, while flexible electrode patches on the spine and forearm delivered motor commands; fingertip sensors provided sensory feedback via cortical mirroring.
