Paralysed people inhabit distant robot bodies with thought alone

They meet people, go to work, even fall in love, all without leaving the comfort of their own home. Now, for the first time, three people with severe spinal injuries have taken the first steps towards that vision by controlling a robot thousands of kilometres away, using thought alone. The idea is that people with spinal injuries will be able to use robot bodies to interact with the world. It is part of the European Union-backed VERE project, which aims to dissolve the boundary between the human body and a surrogate, giving people the illusion that their surrogate is in fact their own body. In 2012, an international team went some way to achieving this by taking fMRI scans of the brains of volunteers while they thought about moving their hands or legs. The scanner measured changes in blood flow to the brain area responsible for such thoughts.
