一 |     (ECNS) -- A 55-year-old woman with high-level quadriplegia has become the first patient at Tongji Medical College in Wuhan, Hubei Province, to undergo fully invasive brain-computer interface (BCI) surgery, the hospital said Thursday.    The patient, identified by the pseudonym Hu Damin, has been bedridden for two years following a spinal cord injury. Doctors implanted eight ultraflexible electrodes into her motor cortex. Each electrode, dozens of times thinner than a human hair, can capture neural signals linked to her intention to move.        The BCI system is designed to bypass the damaged spinal cord and translate brain signals into commands for devices such as computer cursors, smartphones and wheelchairs. Through rehabilitation training, doctors hope to help her regain fine motor functions in her upper limbs.    The implanted device is reportedly China's first high-throughput BCI product capable of recording single-neuron-level signals and has been recognized as an innovative medical device by the National Medical Products Administration.    The surgery marks Tongji Medical College as one of the Chinese medical institutions capable of conducting clinical translation of fully invasive, minimally invasive and non-invasive BCI technologies.    (By Gong Weiwei)                    。    本人于2023年7月4日在淘宝平台后浪教育企业店花费6980元购买品牌视觉设计课程（助学班），总课时182节，并在微信签署电子合同，合同和发票并未提供给我。仅学习了4节课，感觉课程效果不理想，与预期差距很大，于是没有再继续学习。2026年4月22日找机构沟通退费，但班主任已经多次微信迁移联系不上，后与淘宝后浪企业店联...。
