Neuroscientists have made a brain implant that restored decision-making ability in laboratory monkeys whose faculties had been experimentally addled by cocaine. Eventually, researchers hope, such prostheses could boost cognitive abilities of brain-damaged patients.
The prosthetics sported by military veterans and others today are high-tech masterpieces, but they are the evolution of a simple, and age-old, idea. To illustrate that point, the BBC News Health site has gone through the London Science Museum’s wonderful archive of historical medical devices and put together a slideshow of prosthetics dating from seven centuries BCE to the mid-twentieth century. Our favorites: The factory work’s arm with four attachable hammers, the Egyptian toe prosthesis, and the gas-powered arms for a twelve-year-old boy.
