Nuevas aproximaciones al problema del miembro fantasma

The present work analyzes the recent hypothesis related with phantomlimb (PL) genesis. This alteration is characterized by the sensationpresented by people who suffer limb amputation or nerve avulsion, andconsists in the perception, with a high grade of reality, that the limb is still present. The f...
