研究发现,截肢多年后, 大脑还保留手的"地图", Study finds brain retains hand 'map' years after amputation, challenging previous beliefs.

匹兹堡大学的一项新研究与数十年之久的研究相矛盾, 表明大脑在截肢后, A new study from the University of Pittsburgh contradicts decades-old research by showing that the brain does not significantly rewire its body map after an amputation. 在3名手臂截肢者中,脑部扫描显示,丢失手的表示与手术前、甚至五年后的情况相似。 In three individuals with arm amputations, brain scans revealed that the representation of the missing hand remained similar to before the surgery, even five years later. 这一发现表明,大脑保持电路,用于多年移动四肢,这对控制假肢的脑计算机接口功能至关重要。 This finding suggests that the brain maintains circuits used to move a limb for years, which is crucial for the functionality of brain-computer interfaces that control prosthetic limbs.
