OBJECTIVE To demonstrate that amputees performing "virtual" movements of their amputated limb activate cortical areas previously devoted to their missing limb, we studied amputees with functional magnetic resonance imaging (fMRI) and positron emission tomographic (PET) scans and compared the results with those of normal volunteers performing imaginary movements during fMRI acquisitions. METHODS Ten amputees (age range, 33-92 yr; average age, 49 yr; six men and four women; eight upper-limb and… CONTINUE READING
