*The world's first wireless brain computer interface – a system to convert brain waves to FM radio signals which can be decoded into sounds – has been described by a new paper in Public Library of Science. The implant system has been trialled on 26-year-old Eric Ramsey who was left almost entirely paralysed after a car accident 10 years ago.
