In today's ever-changing technology, scenes that once existed only in science fiction movies are gradually becoming a reality. The development of brain-computer articulation has brought new hope to aphasia and paralyzed patients. Recently, two cases published by the research team of Tsinghua University demonstrate the great potential of this technology.
35-year-old Xiaobai, after receiving wireless minimally invasive brain-computer interface implantation surgery in December last year, has been able to control cursor movement through his mind after more than two months of ** training. The doctor explained that by capturing the nerve signals in the motor areas of the brain and decoding them, the patient's motor intention can be accurately recognized, so as to achieve "mind control activities".
Even more excitingly, Mr. Yang, who had been a quadriplegic for 14 years, underwent the same surgery in October last year. Now, he is not only able to control the glove exoskeleton with his mind and partially regain his grip, but he can also pick up a water bottle and drink water autonomously with his robotic hands, which is the first time he has enjoyed the convenience of using his hands since he was paralyzed.
Mr. Yang sighed: "When you want to hold a water bottle, you can hold it with your hand, and that feeling is so happy, which helps a lot to improve the quality of life." His wife was also pleasantly surprised by this technological advancement and looked forward to the future when Mr. Yang would be able to complete more daily activities on his own.
So, how does mind control action work? According to experts, the implanted device in Mr. Yang's head is only the size of a coin, integrating a brain-computer interface processor, wireless communication and power supply interfaces, and electrodes for collecting brain waves. The system also includes an information acquisition and power supply module, a brainwave decoding and translation module, and a pneumatic glove exoskeleton.
There is a coil inside and outside the patient, and the external coil can not only be powered by **, but also transmit the brain signals in the brain to achieve wireless power supply and communication. In this way, the doctor can use the collected signals to direct the pneumatic glove exoskeleton.
Brain-computer interface** is currently mainly used in the medical field, and most of the brain-computer interface clinical trials conducted by scientists around the world are aimed at functional recovery of patients with high paraplegia. Pu Muming, academician of the Chinese Academy of Sciences and academic director of the Center for Excellence in Brain Intelligence of the Chinese Academy of Sciences, introduced that in addition to reading the information of the brain's motor cortex, the joint team also designed a channel for recording the brain's sensory information. This makes action thinking form a complete information circuit, which greatly improves the application of brain-computer interfaces in the field of neuromedicine.
In the future, the team's goal is to create a universal minimally invasive brain-computer interface platform for more brain diseases such as epilepsy and cognitive impairment through iterative development.
The continuous breakthrough of brain-computer articulation not only brings new hope to patients with aphasia and paralysis, but also provides potential ways for patients with other brain diseases. With the further development of technology, we can foresee that brain-computer articulation will play a role in more fields in the future, bringing revolutionary changes to human health and life.
