"Máy tạo nhịp não" điều trị trầm cảm như thế nào?
“Can you tell I’m a robot?” Wu Xiaotian asks his taxi driver as he’s heading home to his apartment (căn hộ) one day. “It’s true. I have a chip in my head that lets me control my emotions.”
Wu’s experience will sound to some like science fiction (khoa học viễn tưởng). On the right side of his chest (ngực), just under the skin, is a device (thiết bị) known as a “brain pacemaker,” (máy tạo nhịp não) which sends tiny electrical pulses (xung điện nhỏ) to electrodes (điện cực) implanted (cấy) in his head. With just the press of a button, his mood can switch in a moment from despair (tuyệt vọng) to delight (vui vẻ).
Sun Bomin, head of functional neurosurgery (phẫu thuật thần kinh chức năng) at Shanghai’s Ruijin Hospital, carried out Wu’s procedure (quá trình) as part of his clinical research (nghiên cứu lâm sàng) into a brain-computer interface (giao diện) for treatment-resistant (kháng trị) depression. The smart technology works by looking for patterns (đặc điểm) in brain activity linked to depression and then automatically interrupts them by stimulating (kích thích) target points in the nucleus accumbens (nhân não), an area deep inside the brain known for its role in feelings of pleasure and reward.
Using the technology, researchers believe they can reliably create “mood settings” that patients can apply depending on their state of mind, allowing them to alleviate (xoa dịu) their symptoms (triệu chứng) almost immediately.
Since receiving the implant surgery, Wu has mostly relied on two settings for his device, which he controls with an app on his phone. He activates (khởi động) “work mode” in the morning, which “powers him up,” giving him a renewed interest in the things around him, and he uses “rest mode” before going to bed, when he begins to feel low and loses his desire to communicate.
