U.S. scientists try to give prosthesis 'consciousness'

in a new experiment by American scientists thatamputees can "feel" their lost arms and handsThis gives hope to the prosthesis to provide "perception"scientists at the Center for and Northwestern University in theexperimented with two patients who lost both arms: changing the course of some nervesreconnecting the broken nerves of the amputee to their chests, according to theAftera few months later,the nerves began to function again in the chest musclesafter stress
,heat and cold in the nerve region, and electrical stimulation,patients said they were able to feel the arms and hands they had lostIn experiments, patients were sometimes able to point out which area of their hands they could feelAt one point, a woman felt strongly that her skin was elongating and that the joint area of the ring finger was stretchingIn addition, they were always able to distinguish between chest nerves and amputations Scientists believe that as they successfully restore this specific "perception" associated with amputation, it could lead to the creation of neurological feedback on devices such as prosthetic hands , prosthetic arms , prosthetic feet and prosthetic legs
