失去手的儿童 重新连接他们的大脑 使用其他身体部位, 研究发现。 Children with missing hands rewire their brains to use other body parts, study finds.

剑桥大学和达勒姆大学的一项新研究发现,具有上肢差异而出生的儿童在生命初期就重组了大脑的细胞皮层,重新规划通常与缺失的手相连的地区,以便处理来自其他身体部分的信号,如手臂、躯体和腿。 A new study by the University of Cambridge and Durham University finds that children born with upper limb differences reorganize their brain’s somatosensory cortex early in life, repurposing areas normally linked to the missing hand to process signals from other body parts like the arm, torso, and leg. 研究人员利用FMRI和感官刺激,观察到由脚趾到前额的大脑图变化广泛而稳定,其驱动力是自动性可塑性。 Using fMRI and sensory stimulation, researchers observed widespread, stable brain map changes from toes to forehead, driven by homeostatic plasticity. 这种适应性支持独特的运动战略,并突出显示大脑在早期发展中的非凡弹性。 This adaptation supports unique movement strategies and highlights the brain’s remarkable resilience in early development. 这些调查结果在 " 慈善联系组织 " 的支持下,可为今后的康复办法提供参考。 The findings, supported by the charity Reach, may inform future rehabilitation approaches.
