Paralyzed Art Teacher Regains Ability to Paint as Brain-Computer Interface Achieves Breakthrough

An Unexpected Drowning Last Year Left Art Teacher Mr. Deng Paralyzed in Both Lower Limbs and Nearly Unable to Move His Hands Independently. He Was Forced to Leave the Lectern, “It Felt Like I Aged Decades Overnight, As If I Had Been Abandoned.” Before the Accident, He Had Planned to Paint a Family Portrait to Surprise His Wife. Now, As The Second Participant in NeuroXess' "Triple-All" Brain-Computer Interface Clinical Trial, He Has Not Only Regained the Ability to Feed Himself but Also Used His Own Hand to Hold a Pen Again and Drew the Family Portrait, “I Feel a Great Sense of Hope for Life. I Hope That Once My Hand Fully Recovers, I Can Personally Teach My Son How to Paint.” On April 23, Reporters from the Jiefang Daily Learned From NeuroXess That Following the Completion of the First Fully Implantable, Fully Wireless, Fully Functional ("Triple-All") Brain-Computer Interface Clinical Implant Developed In-House at the End of 2025, The Second Clinical Trial Has Achieved a Key Breakthrough.

According to the introduction, this brain-computer interface system uses flexible cortical electrodes placed on the surface of the cerebral cortex beneath the dura mater without invading brain tissue. The flexible material fits well with the contour of the cerebral cortex, reducing foreign body stimulation and lowering the probability of tissue rejection and inflammatory responses. As China’s first brain-computer interface system with a built-in battery, the device has its own independent energy storage module, which can stably support a patient's all-day daily use after only a short wireless charging session, without relying on an external power supply for continuous power. This design frees patients from the constraints of external cables and devices, allowing them to freely complete various life scenarios such as bathing, exercising, and daily travel. The neural response time for humans to perform simple voluntary movements like raising a hand or blinking is about 100-200 milliseconds, while the reaction time for daily fine motor skills is approximately 50-100 milliseconds. NeuroXess has achieved an ultra-low latency of just 50 milliseconds from signal acquisition to terminal execution, twice as fast as the average human blink speed. Not only does this reach the leading international level of implantable brain-computer interfaces, but it also breaks through the key threshold for clinical practicality. This means that the device's response speed is close to the natural physiological reaction speed of humans, making the delay almost imperceptible to the brain, achieving a natural experience of "thought and action in sync." For the first time in clinical practice, this trial used functional electrical stimulation technology driven by a brain-computer interface, constructing a complete closed loop of "intention-decoding-stimulation-action": using cortical electrodes to collect and decode motor intentions in real time, bypassing the damaged spinal cord to stimulate peripheral muscles, enabling natural and coordinated finger movements. Clinical verification showed that one month post-surgery, patients had achieved active grasping of the affected hand through thought control and could independently perform high-precision actions such as writing and drawing. Tao Hu, founder and chief scientist of NeuroXess, stated: "Our first clinical case proved that we can do it; our second clinical case proved that it works well and can be promoted. Our goal is not only to make patients move but also to allow them to return to life with quality and dignity."
