The human brain can adapt to changing demands even in adulthood, but MIT neuroscientists have now found evidence of it changing with unsuspected speed. Their findings suggest that the brain has a network of silent connections that underlie its plasticity. The brain's tendency to call upon these connections could help explain the curious phenomenon of "referred sensations," in which a person with an amputated arm "feels" sensations in the missing limb when he or she is touched on the face.
