flag Children with missing hands rewire their brains to use other body parts, study finds.

flag 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. flag Using fMRI and sensory stimulation, researchers observed widespread, stable brain map changes from toes to forehead, driven by homeostatic plasticity. flag This adaptation supports unique movement strategies and highlights the brain’s remarkable resilience in early development. flag The findings, supported by the charity Reach, may inform future rehabilitation approaches.
