There's been a notable first for brain-computer interfacesA commercially-sold BCI has been implanted for the first timeIt comes from Chinese company Neuracle Medical TechnologyThere's been a notable advancement in the field of brain-computer interfaces (BCI) this week: surgeons in China have successfully implanted a commercially sold BCI in the brain of a patient for the first time.As reported by South China Morning Post, the device is called the Neural Electronic Opportunity (NEO), and is manufactured and sold by Neuracle Medical Technology. It's the size of a coin, and is fitted with eight electrodes.While we've seen these kinds of brain implants used in controlled tests and clinical trials, this is the first time a BCI has been bought and implanted — thanks to the China National Medical Products Association approving the NEO for sale in March.It's a field of research and innovation that the Chinese government is keen to do very well in: authorities have put together a blueprint setting out key targets in BCI tech to hit by 2027, with goals around both devices and the framework needed to support them.Just the startNeuralink is working on its own chip (Image credit: Getty Images/NurPhoto)As we know from previous trials of the NEO, the device looks for neural signals from the sensory and motor control regions of the brain. These are then translated into actions that then get transmitted to a metal glove worn by the patient.The system could also be used to control computers, phones, and other devices, as well as robotic limbs, its developers say. These devices will inevitably get smarter and smaller over time, so we can expect many more developments like this in the future.According to reports, the individual involved was in a car crash a decade earlier, leaving them with a damaged spinal cord and impaired hand mobility. After the procedure, the patient was said to be recovering well, with normal brain signaling observed.The obvious comparison point is Neuralink, headed up by Elon Musk. While Neuralink devices have successfully been implanted in several cases, these BCIs don't yet have regulatory approval in the US and aren't available commercially.
