Phantom limb study rewires our understanding of the brain
In a first-of-its-kind study, researchers found that the brain’s control center for a lost appendage can persist long after surgical amputation, which stands in stark contrast to longstanding theories about the brain’s ability to reorganize itself, also known as plasticity. Scientists from the National Institutes of Health (NIH) and their colleagues examined human brain activity before and after arm amputation and found that the loss of a limb does not prompt a large-scale cerebral overhaul.
