flag Study finds brain retains hand 'map' years after amputation, challenging previous beliefs.

flag 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. flag 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. flag 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.
