China has approved the world's first commercial brain chip, which could help paralyzed patients control devices with their thoughts. The brain-computer interface, named NEO, has been cleared for medical use for specific patients with paralysis resulting from spinal cord injuries.
What is the NEO brain chip?
NEO is a brain-computer interface that reads brain activity and translates it into commands for an external device. This implant uses sensors placed near the brain's motor control area. These signals can help a patient operate equipment such as a robotic glove or a computer interface.
What makes the chip particularly notable is its placement method. Brain-computer interfaces can be designed in different ways, with some going deeper than others. NEO adopts a less invasive approach by placing its electrodes on top of the outer membrane that protects the brain.
Medical potential and privacy concerns
The medical benefit of this technology is undeniable. According to the World Health Organization, more than three billion people worldwide live with neurological disorders. For someone who has not been able to move freely or communicate easily for years, regaining even a small amount of control can be profoundly meaningful.
However, if a brain chip can translate your brain signals into digital commands, questions arise about who controls that data and how well it is protected. Brain-computer interfaces take personal data concerns to a new level because the data collected comes directly from the nervous system.
Comparison with Neuralink
Neuralink, co-founded by Elon Musk, has captured significant public attention in the brain chip race in the United States. Neuralink has received approval to begin human trials, and reports indicate implants have been placed in more than 20 people as part of testing. However, the company has not yet received broad FDA approval for general commercial use.
China's approval of NEO applies a different kind of pressure in this field. China aims to bring brain-computer interface technology into its healthcare system and build a major industry around it. The country plans for breakthroughs by 2027 and a globally competitive brain-computer interface industry by 2030.
Cybersecurity and the future
Brain-computer interfaces also raise major questions from a cybersecurity perspective. Since an implant could remain in a person's body for years, long-term support must be part of the agreement. Encryption, strict access controls, medical-grade testing, and clear update policies must be considered from the very beginning.
This technology is currently aimed at patients with serious medical needs. However, these developments show that society needs a broader discussion about the privacy and security of brain data. While the medical potential is incredible, privacy protections must be as strong as the technology itself.
