Top brain-computer interface psychiatrist Lin Xian, faced with patients suffering from "fragmentation of consciousness" caused by out-of-control technology, formed a team with rigorous EEG laboratory leader Shen Tinglan and genius programmer Su Mi to develop the revolutionary "Neural Concerto" therapy. They use the "brain spectrum equalizer" of deep learning to tailor a unique sound wave treatment plan for each patient, from the lost ancient song "Guangling San" to modern rhythms, using the resonance of sound to repair the broken consciousness map. When the shadow of improper use of technology loomed, Lin Xian resolutely teamed up with a cutting-edge game company to plan Jiang Tuo, transforming sophisticated treatment procedures into the world-popular brain-building VR game "Heartstrings Echo", which combines therapy with pleasure. This not only saved countless families, but also promoted the establishment of the industry milestone "Brain-Computer Interface Clinical Access Standards". This is a diagnosis and treatment revolution about the warmth of technology, the benevolence of doctors, and the awareness of guardianship. Lin Xian uses her precise grasp of the "heartstrings" to compose a moving movement that restores the harmony of life at the intersection of brain-computer interface, psychiatric medicine, and artificial intelligence.
