China’s advancements in Brain-Computer Interface (BCI) technology are opening new horizons for patients suffering from paralysis. A team of scientists from Tsinghua University, in collaboration with neurosurgeons from two prominent hospitals in Beijing, have successfully implanted a minimally invasive BCI device in two patients, offering them renewed opportunities for mobility and communication.
A New Dawn in BCI Technology
In October last year, a tetraplegic patient known as Laoyang underwent pioneering surgery at the Xuanwu Hospital of Capital Medical University. Paralyzed from the neck down due to a car accident 14 years prior, Laoyang received an implant called Neural Electronic Opportunity (NEO). Developed by Professor Hong Bo and his team at Tsinghua University’s School of Medicine, NEO is a minimally invasive device designed to bridge neural signals between the brain and external devices.
“The standardization of the surgical procedure is unprecedented,” said Dr. Zhao Guoguang, the leading neurosurgeon for the operation. “Our goal was to install the device safely and effectively, ensuring the patient’s well-being throughout the process.”
The NEO Advantage
The NEO device stands out for its minimally invasive approach. “Our system’s main advantage lies in embedding electrodes between the skull and the dura mater,” explained Professor Hong. “This method protects brain structures, prevents damage to brain cells, and eliminates inflammatory reactions.”
Compared to full-invasive designs like Neuralink’s “Telepathy,” which penetrate deeper into brain tissue, NEO offers a safer alternative with a shorter recovery time. “While more invasive systems may access richer brain signals, they come with greater risks,” Hong noted. “Our approach balances efficacy with patient safety.”
Restoring Hope and Mobility
The second patient, operated on in December at Beijing Tiantan Hospital by Dr. Shan Yongzhi’s team, showcased remarkable progress. Within a month, the patient regained partial hand movement using an air-filled glove and was able to control a computer cursor through brain waves.
“Our system can help patients regain hope and strength in life,” Professor Hong stated. “By translating neural signals into actionable commands, we empower individuals to reconnect with the world around them.”
Future Applications of BCI
The potential of BCI technology extends beyond mobility restoration. “Devices like NEO can be combined with other treatments to address cognitive impairments and complex mental health issues,” Hong envisioned. “Collaboration between researchers and clinicians is key to expanding the clinical applications of this system.”
Echoing the sentiment of renowned neuroscientist Miguel Nicolelis, Dr. Zhao reflected on the impact of BCI: “If someone was once the soloist but lost their voice, through a brain-computer interface, we hope they can join the chorus again, continuing the music and completing their performance.”
As China’s researchers continue to innovate, the advancements in BCI technology herald a promising future for patients worldwide, offering new avenues for treatment and a renewed sense of possibility.
