根据美国约翰斯·霍普金斯大学的新冠疫情数据，截至北京时间9月13日5时21分，美国新冠肺炎确诊病例累计达到95303170例，累计死亡1050507例。另据美国疾控中心公布的数据，自2020年1月至今，美国日均新冠肺炎死亡病例数为320例左右，其中85%为65岁以上的老人，今年已有超过20万美国人死于新冠肺炎。按照目前的趋势，新冠肺炎极有可能连续第三年成为美国致死率第三高的疾病，仅次于心脏病和癌症。    (ECNS) -- A medical team in Shanxi Province on Wednesday performed the region's first invasive brain‑computer interface (BCI) implant surgery, opening up new possibilities for restoring mobility in patients with spinal cord injuries.    The surgery was performed by a team led by Guo Geng, director of the BCI Clinical Research Center at the First Hospital of Shanxi Medical University.    The system enables the patient, who has high-level paralysis for three years, to control external devices through brain signals including computers, smart home equipment.    It can also enable the control of a pneumatic glove to perform daily tasks such as drinking and eating, and may eventually help patients regain independent hand movement.    Stable collection, transmission, and decoding of neural signals have been observed since a flexible cortical electrode, measuring just 10 micrometers thick, was placed on the target brain area.    According to Guo, the system is designed for full internal implantation, which reduces infection risk and allows patients to use it more conveniently in everyday life. Its ultra-flexible electrodes capture brain signals while minimizing damage to surrounding tissue. The system also integrates wireless charging and Bluetooth data transmission, with a response delay as low as 50 milliseconds.    The surgery marks a milestone for invasive BCI research in Shanxi and provides new hope for millions of people with spinal cord injuries and paralysis.    (By Intern Liu Shuangjing, Zhang Dongfang)                    。
